THANK YOU FOR CHOOSING NAD  
We encourage you to take a few minutes now to read right through this  
manual. Investing a little time here at the outset might save you a good  
deal of time later, and is by far the best way to ensure that you make the  
most of your investment in the L 54, and get the most from this powerful  
and flexible home-theatre component.  
The L 54 DVD Receiver is a technologically advanced and highly capable  
product-yet we have invested great effort in making it simple and easy  
to use. The L 54 delivers a range of genuinely useful options for stereo  
listening using powerful digital signal processing and superbly accurate  
digital-audio circuitry. However, we have also been careful to ensure that  
the L 54 is as musically transparent and spatially accurate as possible,  
incorporating much of what we’ve learned from a quarter-century’s  
experience designing audio and home-theatre components. As with all our  
products, NAD’sMusic Firstdesign philosophy guided the L 54’s design,  
such that it can confidently promise you both state-of-the-art surround  
home-theatre and audiophile-quality music listening for years to come.  
One more thing: We urge you to register your L 54 ownership on the NAD  
Worldwide Web site:  
For warranty information contact your local distributor.

UNPACKING AND SETUP  
what’S in the box  
Packed with your L 54 you will find:  
An AM loop antenna  
An FM ribbon-wire antenna with balun  
The HTR 4 remote control with 4 (four) AAA batteries  
This owner’s manual  
Save the packaging  
Please save the box and all of the packaging in which your L 54 arrived. Should you move or otherwise  
need to transport your L 54, this is by far the safest container in which to do so. We’ve seen too  
many otherwise perfect components damaged in transit for lack of a proper shipping carton, so  
please: Save that box!  
chooSing a location  
Choose a location that is well ventilated (with at least several inches to both sides and behind), and that  
will provide a clear line of sight, within 25 feet/8 meters, between the L 54’s front panel and your primary  
listening/viewing position. This will ensure reliable infrared remote control communications. The L 54  
generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly  
possible to stack the L 54 atop other components, but the reverse usually should be avoided.  
Nonetheless, it is generally preferable that the L 54 stands alone. It is especially important that  
sufficient ventilation be provided. If you are contemplating on locating the L 54 within a cabinet or other  
furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.  
QUICK START  
In case you simply cannot wait to experience the performance of your new NAD L 54 DVD Receiver,  
we provide the followingQuick Startinstructions to get you underway. Before the steps below,  
connect your L 54 to a TV/monitor.  
Please make all the connections to your L 54 with the unit unplugged. It is also advisable to power-  
down or unplug all associated components while making or breaking any signal or AC power  
connections.  
plaY a cd or dvd movie  
Connect the L 54’s composite Video or S-VideoMONITOR OUTjack to your TV/monitor’s  
corresponding input.  
Connect your left and right front speakers to the L 54’sLandRoutputs. Make sure to connect  
red to red (“+”) and black to black (“-”) with care to avoid stray wires or strands crossing between  
terminals. If your system includes a powered subwoofer, connect the L 54’sSUBWOOFER PRE-OUT”  
jack to its line input.  
Plug the AC mains plug into the AC outlet; the LED on the front panel will be illuminated blue  
indicating the L 54 is in standby mode ready to accept commands from either the front panel  
power switch or the HTR 4 remote.  
To start playback of the DVD player; pressDVDat the HTR 4 remote’s Device Selector section and  
thenOPEN/CLOSEbutton.  
Insert the media and press [PLAY] button to start playback. You should hear stereo sound, and  
see an image on the TV/monitor. (If one or the other fails to appear, you may need to use either  
the L 54’s on-screen menu system to check assignment of audio and video inputs (See section on  
“Video Outunder the headingOperation.”)  
Enjoy the movie or music, but be sure to set aside time to read this manual thoroughly, and to set up,  
calibrate, and configure your L 54 carefully and completely.

INTRODUCTION  
getting the moSt from the l 54  
ABOUT THE L 54  
Though the L 54 is among the most technically sophisticated integrated Stereo DVD receivers, we  
worked hard to make it one of the most musically transparent home-theatre components available as  
well - this is what we mean by NAD’sMusic Firstdesign philosophy. Here are just a few examples:  
High-performance components used throughout the receiver’s analog audio circuits maximize  
quality from all sources.  
The L 54 incorporates a high quality DVD player with exceptional playability. The player has  
support for DVD video, VCD, SVCD with playback control (PBC), DivX, CD audio such as CD-RW  
as well as recorded MP3, copyright-protected WMA and JPEG files.  
Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.  
EASE OF USE  
Despite the effort NAD has invested in the L 54’s sonic performance, we expended no less in making  
it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and the HTR  
4 universal remote control is equally understandable, as are the L 54’s own front panel and on-screen  
displays (OSD).  
ABOUT THE HTR 4 SYSTEM REMOTE CONTROL  
Packed with your L 54 is the NAD HTR 4 remote control, a full-system remote especially designed  
for easy use and understanding. Be sure to read the sectionUsing the HTR 4 Remote Controlto  
familiarize yourself with the remote’s layout and operations before proceeding to setup your L 54.  
Chances are you will want to use your HTR 4 as your primary way to command your entire A/V system.  
The HTR 4 can be employed to operate additional NAD or other-brand components such as a second  
DVD/CD player, television, satellite/HDTV tuner, VCR, or virtually anything else that operates via  
standard infrared remote control.

power : When the L 54 is first plugged into the AC power, the L 54’s

changing the standby indicator from bright blue to dark and illuminating

ATTENTION!  
Please make all the connections to your L 54 with the unit unplugged. It is also advisable to power down or unplug all associated components while making  
or breaking any signal or AC power connections.  
1
SpeakerS : Connect the left and right terminals to the corresponding  
loudspeakers. Each output’s+(red) terminal and-(black) terminal  
must be connected to the corresponding+and-terminals of the  
loudspeaker. Use extra care to ensure that no stray wires or strands cross  
between posts or terminals at either end.  
3
am antenna : The AM loop antenna supplied with the L 54 (or  
a suitable replacement) is required for AM reception. Open the clip  
terminal lever; insert the wire making sure to match the color-coded  
(white and black) ends of the wire to that of the terminal and close the  
lever ensuring that the lever locks the wire in place. Testing different  
positions for the antenna may improve reception; vertical orientation  
will usually produce the best results. Antenna proximity to large metal  
objects (appliances, radiators) may impair reception, as will attempts to  
lengthen the wire to the loop.  
NOTES  
Use stranded wire of at least 16-gauge (AWG); specialized speaker cable  
may be valuable (consult your NAD audio specialist). Connections to the  
L 54 can be made with banana-type plugs, or using bare wire, or pins, by  
loosening the terminal’s plastic nut, making a clean, neat connection, and  
re-tightening carefully (use the transverse hole through the post for bare-  
wire or pin connections). To minimize the danger of short-circuits, ensure  
that only 1/2-inch of exposed wire or pin is employed in connecting.  
This unit is designed to produce optimum sound quality when  
connected to speakers with impedances within the receiver’s operating  
range. Please check that speakers are rated to be 8 ohms minimum per  
speaker.  
NOTE  
An external AM antenna can improve long distance reception  
substantially; consult your NAD audio specialist or a professional  
antenna installer. Do not connect anything other than a loop antenna  
to the AM ANTENNA terminal.

fm antenna : The supplied wiredipoleFM antenna will connect to  
the FM connector using the suppliedbalunadaptor. It will usually work  
best when mounted on a vertical surface such as a wall, with arms fully  
outstretched forming a horizontal“T”perpendicular to the origin point  
of the signal. Experiment with placement and orientation to yield the  
clearest sound and lowest background noise.

6
pre-out Subwoofer : Connect this output to a powered (“active”)  
subwoofer (or to a power amplifier channel driving a passive system).  
In areas of difficult FM reception, an external FM antenna can yield  
dramatic gains in quality; consult your NAD audio specialist or a  
professional antenna installer.  
ir in : This input is connected to the output of an IR (infrared) repeater  
(Xantech or similar) or the IR output of another component to allow  
control of the L 54 from a remote location. Ask your dealer or custom

SETUP  
Setting up the l 54  
getting Started  
Before you make the first connection to your L 54, you should have the arrangement of your  
listening room/home theater components and furniture mapped out, at least initially. Unfortunately,  
a discussion of the vital questions of loudspeaker placement and listening/viewing positions is  
beyond our scope here. Suffice it to say that these two questions will influence your system’s ultimate  
performance every bit as powerfully as your selection of electronics and speakers. Your NAD audio  
specialist dealer will be happy to advise you and to recommend reference materials.  
DEALING WITH HUM AND NOISE  
Hum and noise sometimes may prove a challenge in audio systems. Note these considerations to help  
prevent hum and noise problems:  
Power all your system’s audio component from AC outlets originating from the same circuit of your  
house wiring. As far as possible, power all audio components from the same outlet, or adjacent  
outlets on the same circuit. It may be useful to power video displays (and computers!) from outlets  
on another circuit, especially if that circuit is supplied from the otherlegof the house wiring.  
Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. It is  
best if they cross at right angles if they must be in close proximity.  
Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are  
secure.  
A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low-  
resistance contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging  
and re-plugging since the gold (or copper) contact plating of typical cable connectors, even very  
high-quality ones, is very thin and easily worn.  
Track down hum/noise problems one component at a time, working backwards from the L 54. That is  
a
Connect the speakers to the L 54 only, and check for hum.  
b
Then connect one component only (a CD player, for example) alone, with no other components  
connected and check for hum.  
c
Connect additional components, one at a time, to the L 54 and check for hum.  
At each stage, if hum/noise appears, examine the audio cabling and AC-power routing of the new  
component. In some cases, moving the new component’s AC cord to a different outlet, or installing a  
ground-lift (3-to-2-prong adapter) on its power cord, will eliminate the hum.  
FACTORY DEFAULT SETTINGS  
Sometimes power spikes and drop-outs may from time to time cause some inadvertent functionality.  
The procedure below will set the L 54 to factory default settings

SrS truSurround  
SRS Labs developed TruSurround®, a patented technology that accepts any multichannel source such  
as Dolby Digital, Dolby Surround or DTS, including MPEG 1 and 2 and transforms it into a compelling  
surround sound experience over just two speakers or headphones.  
TruSurround is suited for any environment where multichannel content is experienced without the  
benefit of having surround sound speakers installed. With TruSurround, incoming multichannel audio  
is processed into two channels and delivered over stereo speakers, giving the listener a completely  
immersive experience and the sensory perception that additionalphantomspeakers surround them.  
To activate SRS TruSurround, pressAUDIO MODEat the front panel or HTR 4 remote. Select SRS mode.  
Toggle the SRS to ON or OFF using the L 54’s volume knob or the HTR 4 volume  
keys.  
NOTE  
SRS TruSurround is designed to be used with surround encoded soundtracks, such as those found on  
movies and music video DVDs. Results with stereo music soundtracks typically found on CDs can be  
variable and we generally do not recommend SRS for enhancing these programs. Furthermore, SRS  
decoding is only available on digital sources and cannot be selected for analog sources such as FM  
radio and VCR inputs.

left and right (balance adjuSt) Setup  
Adjusting the relative balance of your system’s loudspeakers ensures that surround-sound  
recordings, whether music or film, will present the balance of effects, music, and dialog that the  
artists intended. Additionally, if your system incorporates a subwoofer it establishes a correct  
relationship between the volume of the subwoofer and the other speakers, and thus of low-  
frequencies (bass) to other sonic elements.  
After selectingAUDIO MODE, toggle fromLEFTandRIGHTlevel adjustment and fine tune the level  
of each channel with the volume knob or remote’s volume  
keys.  
adjuSting the tone controlS  
The L 54 is fitted with BASS and TREBLE tone controls to adjust the tonal balance of your system.  
Maximum and minimum values for both tone controls are -/+ 10 dB. Bass/treble settings affect only  
the front left/right channels, not the subwoofer.

dYnamic range control (drc)  
You can select the effective dynamic range (subjective range from soft to loud) for playback of  
Dolby 2.0 soundtracks. Settings of 25%, 50% and 75% progressively reduce dynamic range, making soft  
sounds comparatively louder while limiting the peak loudness of loud ones.  
The 100% setting is best for late-night sessions or other times when you wish to retain maximum dialog  
intelligibility while minimizing overall volume levels. To maintain full dynamic range, set DRC to OFF.  
NOTE  
To access DRC feature, always set SRS first to OFF.  
INPUT SELECT  
Aside from the L 54’s internal DVD and tuner section, the L 54 is also equipped with 3 inputs - Audio/  
Video inputs labeledCAB/SAT, VCRandVIDEO 4 (VIDEO 4 on the front panel). The input becomes  
active whenever it is selected.  
From the front panel, press theINPUT SELECTbutton to toggle from DVD, CABLE/SAT, VCR,  
VIDEO 4, AM, FM and then back to DVD. If the L 54 is in standby mode, theSTOP/OPENbutton will  
automatically select DVD mode.  
Incoming digital and audio signals present at either digital or analog audio are assigned to their fixed  
inputs - CAB/SAT and VCR. Assign either coaxial or analog audio to CABLE/SAT input by toggling the  
L 54’sDISPLAYbutton on the front panel. The selected audio input will be displayed on the VFD after  
releasing theDISPLAYbutton. The same procedure is applicable when assigning optical or analog  
audio to the VCR input.  
The assigned audio input will always be recalled whenever that input is selected via the front panel  
INPUT SELECT or the HTR 4 remote’s input-select buttons.  
It is not necessary to connect at the same time both analog audio and digital audio input for every  
video input you employ. It is preferable to make only digital audio link to the L 54 for audio playback.  
This avoids possible confusion and ensures that the L 54’s high performance digital audio circuitry will  
always be employed.  
ADJUSTING THE VOLUME  
In addition to the Volume knob, use the HTR 4’s VOL  
or lowering the channels altogether. With HTR 4’s VOL  
the volume by 1 dB increments. If you hold down VOL  
keys to adjust the volume of the L 54 raising  
keys, a momentary keypress will change  
keys, the volume level change willrun-  
onuntil the key is released. Since recordings vary considerably in overall average level, there is no  
imperative to listen at any particular volume setting. A setting of -20 may soundas loudfrom one CD  
or DVD as -10 does from another.  
The L 54 will power-up from Standby mode at whatever master volume setting was last used; however,  
if the prior setting is greater than –10 dB, the L 54 will power up at -10 dB. This prevents inadvertently  
beginning a session at excessive volume.  
muting the Sound  
Use the HTR 4’sMutekey to silence all channels completely. Muting is always available regardless of  
the source or listening mode selections. Note that adjusting the volume upward via the HTR 4 or the  
front panel knob automatically releases the mute function.  
ADJUSTING THE SUBWOOFER LEVEL TRIM “ON THE FLY”  
You can make changes to the relative level of subwoofer output. This may prove useful in a number of  
circumstances; for example to reduce excessive deep bass (or enhance deep bass) by lowering (raising)  
the subwoofer level.  
Use the HTR 4’sSUBkeys for direct-access level adjustment of these channels over a range of 12 dB.

OPERATION  
uSing the l 54’S am/fm radio  
The L 54’s internal AM/FM tuner offers very high quality sound from radio broadcasts. The reception  
and sound quality will always be dependent to a degree however on the type of antenna(s) used as  
well as proximity to the broadcast origin, geography and weather conditions.  
ABOUT ANTENNAS  
The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using  
the includedbalunadapter and should be fully extended to form a“T. This folded-dipole antenna  
will usually work best when oriented vertically, with the arms of its“T”fully outstretched and arranged  
perpendicular to the origin of the desired broadcast. There are norules,however, and experimenting  
freely with antenna placement and orientation may yield the clearest sound and lowest background  
noise.  
In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If radio  
listening is important to you, consider consulting an antenna installation professional to optimize your  
system.  
The supplied AMloopantenna will usually provide adequate reception. However, an exterior AM  
antenna can be used to improve reception. Consult an antenna professional for more information.

CHOOSING FM MUTE/MODE  
The front-panelFM MUTE/MODEkey is a dual-purpose control. In the normal position, “STand  
“MUTEicons on the VFD are lit; only the stations with a strong signal can be listened to, and the noise  
between stations is muted.  
Pressing theFM MUTE/MODEbutton again (“STandMUTEicons on the VFD are extinguished)  
allows distant and potentially noisy stations to be received. Noise is reduced if the FM station signal  
level is less than the FM Stereo threshold (since mono FM is inherently less noise-prone) though at the  
sacrifice of the stereo effect.  
ABOUT RDS  
The Radio Data System (RDS) permits compatible tuners to display text determined by the broadcaster.  
The L 54 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). However, not  
every FM station incorporates RDS in its broadcast signal. In most areas you will find from one to  
several RDS-enabled stations, but it is by no means impossible that your favorite stations will not be  
broadcasting RDS data.  
VIEWING RDS TEXT  
When an RDS-enabled FM broadcast is tuned, after a brief delay theRDSsymbol will light in the  
L 54’s front panel readout and the readout’s character section will show its station-name (PS) text:  
“ROCK101,”for example.  
Press the front panel DISPLAY key to toggle the readout between this and the station’s radio-text (RT)  
readout, if any, which might scroll song- or artist-name or any other text of the station’s choosing.

OPERATION  
uSing the htr 4 remote control  
SPECIFICATIONS  
Controls up to 8 devices.  
44 function keys.  
Learns up to 352 commands.  
Records up to 44 macros with a maximum of 64 commands each.  
Configurable punch-through.  
Key illumination with programmable timeout.  
Upgradable.  
Contains pre-programmed library of NAD remote codes.  
The NAD HTR 4 is ready to operate the L 54 right out of the box, but it is really eight remotes in one.  
Each of the 8 Device Selector keys at the top of the handset can call up a newpageof remote control  
codes to be transmitted by the remaining 44 keys. You mayteachcodes from any infrared-remote  
controlled component, regardless of brand, to any or all of these.  
Obviously, the most logical system is that you teach the codes from your DVD player to the [DVD]  
Device Selectorpage,your television’s codes to the [TV]page,and so on, but there is no required  
scheme: You may load any commands to any key on any page (seeLearning Codes From Other  
Remotes,below).  
The HTR 4 is already preprogrammed with a full complement of commands for the L 54 on its [AMP]  
Device Selector page, and as well as with library commands to operate most NAD-brand DVD  
or CD components on the corresponding Device Selectorpages.”These default commands are  
permanent: Even if you teach the HTR 4 new commands to take their place, the underlying library  
commands remain in place and can easily be recalled should you add an NAD component to your  
system later (seeDelete Mode, below).  
Note: For use with the L 54, it should not be necessary to re-program any keys on the HTR 4 [AMP]  
page. However, in order for the HTR 4 to control your specific NAD-brand components you may need  
to load one or more different code-libraries (seeLoading Code Libraries,below).  
CONTROLLING THE L 54  
The HTR 4 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [DVD,]  
[TV,] and so on—set the handset’s remaining keys to apageof commands to control a particular  
component. A Device Select key determines only what component the HTR 4 will command; it does  
not perform any function on the L 54. All of the remaining keys are function keys that canlearn”  
control codes from virtually any infrared remote controller, allowing you to teach the codes of your  
equipment, regardless of brand, to the HTR 4.  
However, the HTR 4 is already preprogrammed to operate the L 54. All of the function keys on the  
[AMP] Device Selectorpageperform L 54 functions. (The HTR 4 can also command many other NAD  
components, from its [DVD,] [CD,] [TUNER,] and [CUSTOM] pages.)  
It is important to note that certain HTR 4 keys perform different functions depending on the selected  
Device Selectorpage.”The color of the Device Selector key-labeling corresponds to the labeling of  
the function keys. Most centrally, the orange [AMP] Device Selectorpagecorresponds to the orange  
input-select labeling above the numeric keys: When the HTR 4’s [AMP] Device Selector page is active,  
these keys select the Receiver inputs. Similarly, the purple [DVD] Device Selectorpagecorresponds to  
several purple labels, the green [TV] page to green labels, and so on.

LEARNING CODES FROM OTHER REMOTES  
Begin by positioning the HTR 4nose-to-nosewith the source remote so the two devicesinfrared  
windows are about 2 inches apart.  
Enter Learning Mode: On the HTR 4, simultaneously press-and-hold for 3 seconds both a Device  
Selector key and the key until the Learn LED at the center of the HTR 4 turns steady green.  
Press the HTR 4’s function key you wish to teach a command; the Learn LED will turn amber.  
Press-and-hold the function key on the source remote: The HTR 4’s Learn LED will flicker amber for  
a second or two, then turn solid green. The command is learned.  
Press the HTR 4’s Device Selector key again to exit the learning mode.  
If the Learn LED does not flicker amber you may need to vary the distance between the remotes. If  
the Learn LED turns red rather than green, that particular command of that source remote command  
could not be learned.  
cancel operation  
You can cancel configuring a key, by pressing the active Device Selector key before the learn process is  
complete; the Learn LED will turn red.  
example: LearningDVD Pause”  
Position the HTR 4 and your DVD player’s remote as described above.  
On the HTR 4, simultaneously press-and-hold [DVD] and ; the Learn LED turns steady green.  
Press the HTR 4’s key; the Learn LED turns amber.  
Press-and-hold the DVD player’s remote’s pause key; the HTR 4’s Learn LED flickers amber and then  
turns solid green. The command is learned.  
Press [DVD] again to exit the learning mode.  
PUNCH-THROUGH  
The HTR 4’spunch-throughfunction allows you to retain a function key from one Device Selectpage”  
to another, so that, for example, the AMP [AUDIO MODE] function might still control the L 54 when the  
DVD Device Selector page is active.  
NOTE  
The HTR 4’s [VOL] keys are pre-programmed as “punched-through” for all Device Select pages: [VOL]  
will operate the L 54’s volume regardless of the currently selected device. The [SUB] level control is  
similarly pre-programmed as punched-through.  
To set a punch through, after entering the Learning Mode, and pressing the desired key to be punched  
through, simply press the device key twice of the device to punch through to. The status LED will turn  
green; press the Device Selector key again to exit Learning Mode.  
example: Punch-through AMP [AUDIO MODE] key to the DVDpage”  
On the HTR 4, simultaneously press-and-hold [DVD] and ; the Learn LED turns steady green.  
Press [AUDIO MODE]; the Learn LED turns amber.  
Press [AMP] twice; the Learn LED turns green.  
Press [DVD] again to exit the learning mode.  
COPY COMMAND FROM ANOTHER BUTTON  
You may copy a command from any HTR 4 key to any other key. To copy a key function, after entering  
the Learning Mode, and pressing the desired key to be copied to, simply press the device key from  
which you wish to copy, having first pressed its Device Selector key if it resides on anotherpage.”The  
status LED will turn green; press the Device Selector key again to exit Learning Mode.  
example: Copy the Pause command from the CD page to the AMP key:  
On the HTR 4, simultaneously press-and-hold [AMP] and ; the Learn LED turns steady green.  
Press (pause); the Learn LED turns amber.  
Press [CD]; press (pause); the Learn LED turns green.  
Press [AMP] again to exit the learning mode.  
NOTE  
The copy and punch-through functions are similar. However, if you copy a command and then  
subsequently delete, or over-write the original (source-key) command , the copied-to key’s  
command remains unchanged. If you punch-through to a command and then delete or over-write  
the original key, the punched-through functions also change accordingly.

MACRO COMMANDS  
Amacrocommand is a series of two or more remote codes issued automatically from a single  
keypress. You might use a macro to automate a simple command sequence, such as, “Turn on the DVD  
player and then pressplay.Or you might compose an elaborate macro to power up an entire system,  
select a source, choose a Listening Mode, and begin playback—again, all from a single keypress. The  
HTR 4 can store one macro on each of its function keys (these exclude the Device Selector keys).  
NOTE  
Macros are independent of the currently selected device.  
RECORDING MACROS  
To record a macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR  
4 function key to which you wish to assign the macro, until the status LED turns green. The macro  
button will also light up.  
Press the sequence of function keys to be recorded into the macro, being sure to first press the  
requisite Device Selector key for each function (you may switch devices while recording the macro as  
many times as necessary), allowing you to create macro containing commands from more than one  
Device Selectorpage.”  
When you have finished entering the desired command sequence, press [MACRO] again  
to store the macro; the Learn LED and [MACRO] key illumination will turn off.  
NOTE  
Each macro can store a maximum of 64 command steps. If you exceed this number, the macro will  
be stored automatically after the 64th command is added.  
Example: Record a Macro to the [0] key to Turn on the L 54, Select the DVD Input, and Commence  
Playback:  
On the HTR 4, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns  
steady green.  
Press [AMP]; press [ON]; press [1] (redDVD”); press [DVD]; press [ ] (Play) - the Learn LED blinks as  
each step is added.  
Press [MACRO] again to exit the macro-record mode.  
To clear a macro, perform the above steps without entering any functions.  
executing macroS  
To execute a macro, press and release [MACRO]; its key illumination lights for 5 seconds. While it  
remains lit, press an HTR 4 key to which a macro has previously been stored.  
The corresponding macro will run; as each step executes, itsparentDevice Selector’s key flashes lights  
briefly; when execution is finished, the [MACRO] key illumination goes out. Pressing any other HTR 4  
key while a macro is executing will abort the macro. Remember that you must hold the HTR 4 so that  
its infrared emitter can activate the target components.  
NOTE  
When a macro executes, a 1 second delay is automatically inserted between its commands. If  
you need more than a 1 second delay between particular commands — for example, to permit a  
component to power up completely — you can record “empty” steps into the macro by changing  
Device Selector “pages” without entering actual command functions.

BUTTON ILLUMINATION TIMEOUT  
The HTR 4’s key-illumination can be set to remain lit for 0-9 seconds. The default value is 2 seconds. To  
set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 4’s [DISP] and  
the [0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash  
twice to confirm the new setting. When set to zero, the illumination will not turn on at all.  
NOTE  
Key illumination is the biggest drain on the HTR 4’s batteries. A short key-illumination timeout will  
extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still  
further.  
FACTORY RESET  
The HTR 4 can be reset to its factory state, deleting all learned commands, copied and punched-  
through keys, macros, and other setup information, reverting all keys to their pre-programmed library  
commands.  
To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 4’s [ON] and  
[RTN] keys; the Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is  
complete; the Learn LED will turn red, indicating the remote has been reset.  
NOTE  
You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not reset;  
should this occur, repeat the full procedure.  
DELETE MODE  
The HTR 4 can store learned, copied, anddefault librarycommands on any single key (The default  
library commands are the pre-programmed NAD codes, such as the native L 54 commands on the  
[AMP]page.”).  
You can delete commands by layers backdownto the default library command on any key, removing  
learned commands, punched-through functions, and copied keys.  
NOTE  
The default library commands cannot be deleted, so you need not worry that using Delete Mode  
might cause irreparable changes.  
To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired key’s Device  
Selector key and the [RTN] key, until the Learn LED turns green. Press the function key whose  
command you wish to delete; the Learn LED flashes; the number of times indicates which type of

SEARCH MODE  
If none of the codes from the table, when entered, turns on the component, and if you are quite sure  
you have followed the above procedure completely and carefully, you may want to try thesearch”  
method as follows:  
Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired Device  
Selector key and the [PROGRAM] button until the Learn LED turns green. Now press-and-hold the  
HTR 4’s [ ] or [ ]) key; the remote will step through all the available codes at a rate of approximately 1  
per second.  
When the component turns off, immediately release the cursor key; press [ENTER] to accept that code-  
library and exit the Library Mode. Try a few commands; should you prove to have stepped past the  
needed code-library, re-enter the Library Mode and use the cursor key to step back to it.  
NOTE  
It is possible that search mode will find code-libraries that operate, at least partially, some other  
brand (non-NAD) components. You may certainly exploit such capabilities as you find them.  
However, since we can only ensure the completeness or accuracy of NAD code-libraries, we cannot  
support the HTR 4’s operation with other-brand components.

CHECKING CODE-LIBRARY NUMBER  
You can check the current code-library on any Device Selector key as follows. Enter Library Mode by  
simultaneously pressing-and-holding for 3 seconds both the desired component’s Device Selector key  
and the [PROGRAM] key until the Learn LED turns green. Press the [DISP] key; the HTR 4 indicates the  
current code-library by flashing its [CUSTOM], [VCR], and [MACRO] keys.  
For example, to indicate code-library #501, the HTR 4 will flash [CUSTOM] 5 times, pause, and then flash  
[MACRO] once. You might wish to make a note of your componentscode-library numbers.
