1
the supplied hexagon SEMS screws (4) and flat  
washers (4).  
To install the transceiver, select a safe, convenient  
location inside your vehicle that minimizes danger to  
your passengers and yourself while the vehicle is in  
motion. Consider installing the unit at an appropriate  
position so that knees or legs will not strike it during  
sudden braking of your vehicle. Try to pick a well  
ventilated location that is shielded from direct sunlight.  
Double check that all hardware is tightened to prevent  
vehicle vibration from loosening the bracket or  
transceiver.  
1 Install the mounting bracket in the vehicle using the  
supplied self-tapping screws (4), flat washers (4), and  
spring washers (4).

4 Confirm the correct polarity of the connections, then  
attach the power cable to the battery terminals; red  
connects to the positive (+) terminal and black  
connects to the negative (–) terminal.  
DC POWER CABLE CONNECTION  
1
Locate the power input connector as close to the transceiver as  
possible.  
Use the full length of the cable without cutting off excess  
even if the cable is longer than required. In particular,  
never remove the fuse holders from the cable.  
MOBILE OPERATION  
Red  
The vehicle battery must have a nominal rating of 12 V.  
Never connect the transceiver to a 24 V battery. Be sure  
to use a 12 V vehicle battery that has sufficient current  
capacity. If the current to the transceiver is insufficient,  
the display may darken during transmission, or transmit  
output power may drop excessively.  
Black  
Fuse holder  
Fuse holder  
5 Reconnect any wiring removed from the negative  
terminal.  
1 Route the DC power cable supplied with the  
transceiver directly to the vehicle’s battery terminals  
using the shortest path from the transceiver.  
6 Connect the DC power cable to the transceiver’s  
power supply connector.  
If using a noise filter, it should be installed with an  
insulator to prevent it from touching metal on the vehicle.  
Press the connectors firmly together until the locking tab  
clicks.  
We recommend you do not use the cigarette lighter  
socket as some cigarette lighter sockets introduce an  
unacceptable voltage drop.  
The entire length of the cable must be dressed so it is  
isolated from heat, moisture, and the engine secondary  
(high voltage) ignition system/ cables.  
Fuse holder  
2 After the cable is in place, wrap heat-resistant tape  
around the fuse holder to protect it from moisture and  
tie down the full run of cable.  
3 To prevent the risk of short circuits, disconnect other  
wiring from the negative (–) battery terminal before  
connecting the transceiver.

2 Connect the transceiver’s DC power connector to the  
FIXED STATION OPERATION  
connector on the DC power cable.  
In order to use this transceiver for fixed station operation,  
you will need a separate 13.8 V DC power supply (not  
included). The recommended current capacity of your  
power supply is 12 A.  
Press the connectors firmly together until the locking tab  
clicks.

REPLACING FUSES  
ANTENNA CONNECTION  
If the fuse blows, determine the cause, then correct the  
problem. After the problem is resolved, replace the fuse.  
If newly installed fuses continue to blow, disconnect the  
power cable and contact your authorized KENWOOD  
dealer or an authorized KENWOOD service center for  
assistance.  
Before operating, install an efficient, well-tuned antenna.  
The success of your installation will depend largely on  
the type of antenna and its correct installation. The  
transceiver can give excellent results if the antenna  
system and its installation are given careful attention.  
1
Use a 50 impedance antenna and low-loss coaxial  
feed line that has a characteristic impedance of 50 , to  
match the transceiver input impedance. Coupling the  
antenna to the transceiver via feed lines having an  
impedance other than 50 reduces the efficiency of the  
antenna system and can cause interference to nearby  
broadcast television receivers, radio receivers, and other  
electronic equipment.  
Note: E market models use an N-type antenna connector while other  
models use an M-type (SO-239) connector.  
Fuse Location  
Fuse Current Rating  
Transmitting without first connecting an antenna or other matched  
load may damage the transceiver. Always connect the antenna to  
the transceiver before transmitting.

OPERATING BASICS  
SWITCHING THE POWER ON/OFF  
ADJUSTING THE SQUELCH  
1 Press [ ] (Power) to switch the transceiver power ON.  
The purpose of Squelch is to mute the speaker when no  
signals are present. With the squelch level correctly set,  
you will hear sound only while actually receiving signals.  
The higher the selected squelch level, the stronger the  
signals must be to receive.  
A high pitched double beep sounds and a Power-on  
message {page 60} appears briefly, followed by the  
frequency and other indicators.  
The appropriate squelch level depends on the ambient  
RF noise conditions.  
4
1 Press [F], [REV].  
The current squelch level appears.  
2 To switch the transceiver OFF, press [ ] (Power) (1s).  
When you turn the transceiver OFF, a low pitched  
double beep sounds.  
The transceiver stores the current frequency and  
parameters when it is turned OFF and recalls these  
parameters the next time you turn the transceiver ON.  
2 Turn the Tuning control to adjust the level.  
Select the level at which the background noise is just  
eliminated when no signal is present.  
ADJUSTING THE VOLUME  
The higher the level, the stronger the signals must be to  
receive.  
Turn the Volume control clockwise to increase the audio  
output level and counterclockwise to decrease the output  
level.  
10 different levels can be set.  
(0: Minimum ~ 9: Maximum; 1 is the default value)  
If you are not receiving a signal, press the Mic PF key  
assigned the MONI function {page 59}, then adjust the  
Volume control to a comfortable audio output level. Press  
the MONI key again to cancel the Monitor function.  
3 Press any key other than [ ] (Power) to store the  
new setting and exit the squelch adjustment.

OPERATING THROUGH REPEATERS  
Repeaters, which are often installed and maintained by  
OFFSET PROGRAMMING FLOW  
radio clubs, are usually located on mountain tops or  
other elevated locations. They generally operate at  
higher ERP (Effective Radiated Power) than a typical  
station. This combination of elevation and high ERP  
allows communications over much greater distances  
than communicating without using repeaters.  
q
Select a receive frequency.  
w Select an offset direction.  
Most repeaters use a receive and transmit frequency  
pair with a standard or non-standard offset (odd-split).  
In addition, some repeaters must receive a tone from the  
transceiver to be accessed. For details, consult your  
local repeater reference.  
e
Select an offset frequency  
(only when programming odd-split  
repeater frequencies).

Note:  
REVERSE FUNCTION  
You can turn the Reverse function ON when you are operating in  
Simplex Mode. However, it does not change the Transmission/  
Reception frequencies.  
The reverse function exchanges a separate receive and  
transmission frequency. So, while using a repeater, you  
can manually check the strength of a signal that you  
receive directly from the other station. If the station’s  
signal is strong, both stations should move to a simplex  
frequency and free up the repeater.  
If pressing [REV] places the reception frequency outside the  
allowable range, an error tone sounds and the function does not  
operate.  
If pressing [REV] places the transmission frequency outside the  
allowable range, pressing Mic [PTT] causes an error tone to  
sound and transmission is inhibited.  
You cannot switch Reverse ON or OFF while transmitting.  
AUTOMATIC SIMPLEX CHECK (ASC)

NORMAL SCAN  
PROGRAM SCAN  
When you are operating the transceiver in VFO Mode,  
3 types of scanning are available: Band Scan, Program  
Scan, and MHz Scan.  
You can limit the scanning frequency range. There are  
3 memory channel pairs (L0/U0 ~ L2/U2) available for  
specifying the start and end frequencies. Program Scan  
monitors the range between the start and end  
frequencies that you have stored in these Memory  
Channels. Before performing Program Scan, store the  
Program Scan frequency range to one of the Memory  
Channel pairs (L0/U0 ~ L2/U2).  
BAND SCAN  
The transceiver scans the entire band of the frequency  
you selected. For example, if you are operating and  
receiving at 144.525 MHz, it scans all the frequencies  
available for the VHF band. (Refer to receiver VFO  
frequency range in the specifications {page 72}.) When  
the current VFO receive frequency is outside the Program  
Scan frequency range {below}, the transceiver scans the  
entire frequency range available for the current VFO.

SELECTIVE CALL  
Note: CTCSS and DCS do not cause your conversation to be private  
CTCSS AND DCS  
or scrambled. It only relieves you from listening to unwanted  
conversations.  
You may sometimes want to hear calls from only specific  
persons or groups. In this case, use Selective Call. This  
transceiver is equipped with CTCSS (Continuous Tone  
Coded Squelch System) and DCS (Digital Coded Squelch).  
These Selective Calls allow you to ignore (not hear)  
unwanted calls from other persons who are using the same  
frequency. The transceiver unmutes only when it receives  
a signal having the same CTCSS tone or DCS code.  
CTCSS  
A CTCSS tone is a sub-audible tone and is selectable  
from among the 42 tone frequencies listed in the table  
on page 47. The list includes 37 EIA standard tones and  
5 non-standard tones.  
To activate CTCSS, press [F], [CALL].  
TM-271  
As you press [F], [CALL], the selection cycles as follows:  
“OFF” “TONE” “CTCSS” “DCS” “OFF”.  
“CT” appears on the upper part of display, indicating that  
the CTCSS function is activated.  
CTCSS freq.:  
82.5 Hz  
When CTCSS is ON, you will hear calls only when the  
selected CTCSS tone is received. To answer the call, press  
and hold Mic [PTT], then speak into the microphone.

DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS  
When DTMF TX Hold is activated {page 51}, you do not  
need to continuously press Mic [PTT] to remain in  
transmission mode. However, transmission mode is  
retained for only 2 seconds after pressing a key, so if the  
next key is not pressed within this time limit, the  
transceiver stops transmitting.  
This transceiver provides you with 10 dedicated DTMF  
Memory Channels. You can store a DTMF number (16  
digits max.) in each of these channels to recall later for  
speed dialing.  
Many repeaters in the U.S.A. and Canada offer a service  
called Autopatch. You can access the public telephone  
network via such a repeater by sending DTMF tones. For  
further information, consult your local repeater reference.
