POWER SOURCES
You can operate the CTR-98 using
internal battery power or the supplied
AC power cord.
Cautions:
• Always dispose of the old batter-
ies promptly and properly.
• Never leave dead, old, or weak
batteries in the CTR-98. They
can leak chemicals and corrode
or damage electronic circuits.
INSTALLING BATTERIES
You can power the CTR-98 from four
D batteries (not supplied). For the
best performance, we recommend
alkaline batteries, such as Radio
Shack Cat. No. 23-550.
• If you do not plan to use batter-
ies in the CTR-98 for a month or
more, remove the batteries to
protect the CTR-98 from possi-
ble battery leakage.
1. Press the battery compartment
cover’s tabs and pull out the
cover to remove it.
USING AC POWER
You can power the CTR-98 from
standard AC power using the sup-
plied AC power cord.
Use a flatblade screwdriver to set
VOLTAGE SELECTOR 120V/OFF/
230V to the correct setting (120V in
North America).
2. Install the batteries as indicated
by the polarity symbols (+ and –)
marked above the compartment.
Cautions:
• Use only fresh batteries of the
required size and type.
• Never mix fresh with old bat-
teries.
3. Replace the cover.
If the CTR-98 does not operate prop-
erly or if the sound weakens or dis-
torts, replace the batteries.

Insert the AC power cord’s recepta-
cle into the AC IN jack on the back
of the CTR-98, then plug the AC
power cord into a standard AC outlet.
Note: The internal batteries automat-
ically disconnect when you connect
the AC power cord to the CTR-98.

USING AN EARPHONE
For private listening, you can con-
nect a monaural earphone (not sup-
plied) with a /8-inch plug to the
CTR-98. Your local Radio Shack
store carries a wide selection of ear-
phones.
LISTENING SAFELY
To protect your hearing, follow these
guidelines when you use an ear-
phone.
1
• Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.
1
Insert the earphone’s /8-inch plug
into the EAR jack on top of the CTR-
98.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not
cause discomfort might still
damage your hearing.
Note: Connecting an earphone auto-
matically disconnects the built-in
speaker.
TRAFFIC SAFETY
Do not wear an earphone while oper-
ating a motor vehicle or riding a bicy-
cle. This can create a traffic hazard
and is illegal in some areas.
Even though some earphones are
designed to let you hear some out-
side sounds when listening at normal
volume levels, they still present a
traffic hazard.

CARE AND MAINTENANCE
Your Radio Shack CTR-98 4-Band
Wipe the CTR-98 with
a damp cloth occa-
sionally to keep it
looking new. Do not
use harsh chemicals,
cleaning solvents, or
strong detergents to
clean the CTR-98.
CLEANER
Portable Radio Cassette Recorder
with Multi-Voltage Selection is an ex-
ample of superior design and crafts-
manship. The following suggestions
will help you care for your CTR-98 so
you can enjoy it for years.
Keep the CTR-98 dry.
If it gets wet, wipe it
dry immediately. Liq-
uids might contain
minerals that can cor-
rode the electronic cir-
cuits.
Modifying or tampering with the
CTR-98’s internal components can
cause a malfunction and might inval-
idate its warranty and void your FCC
authorization to operate it. If your
CTR-98 is not performing as it
should, take it to your local Radio
Shack store for assistance.
Handle the CTR-98
gently and carefully.
Dropping it can dam-
age circuit boards and
cases and can cause
the CTR-98 to work
improperly.
Use and store the
CTR-98 only in nor-
mal temperature envi-
ronments.
Temperature
ex-
tremes can shorten
the life of electronic
devices and distort or
melt plastic parts.
Keep the CTR-98
away from dust and
dirt, which can cause
premature wear of
parts.

TAPE TIPS
Preventing Accidental Erasure
Cassette tapes have two erase-pro-
tection tabs — one for each side.
When a tab is in place, you can
record on that side. To prevent
RECORD from being pressed and
protect a recording from being acci-
dentally recorded over or erased, re-
move one or both of the cassette
tape’s erase-protection tabs.
Recommended Tapes
Tape quality greatly affects the quali-
ty of the recording. We recommend
extended-range or low noise type 1
regular length (60- or 90-minute) nor-
mal-bias cassette tapes. We do not
recommend long-play cassette tapes
such as C-120s because they are
thin and easily tangle.
Erasing a Cassette Tape
To record over a cassette tape, sim-
ply record as usual. The cassette
deck records over the previous re-
cording.
If you later decide to record on a tape
side after you have removed the
erase-protection tab, place a piece of
strong plastic tape over that side’s
erase-protection hole. Be sure you
cover only the hole originally covered
by the erase-protection tab.
Notes:
• You must set FUNCTION to
RADIO OFF/TAPE and the unit
must be placed in a very quiet
room.
• You can quickly erase both sides
of a cassette tape using a bulk
tape eraser such as Cat. No. 44-
232, available at your local
Radio Shack store.
Caution: Removing the erase-protec-
tion tabs does not prevent a bulk
eraser from erasing a cassette tape.

Restoring Tape Tension and Sound
Quality
3. Open the cassette compartment
cover.
4. Press and hold down the erase-
protection tab sensor, then press
RECORD to expose the record/
playback and erase heads.
After you play a cassette tape sever-
al times, the tape might become
tightly wound on the reels. This can
cause playback sound quality to de-
teriorate.
To restore the sound quality, fast-for-
ward the tape from the beginning to
the end of one side, then completely
rewind it. Then loosen the tape reels
by gently tapping each side of the
cassette’s outer shell on a flat sur-
face.
Caution: Be careful not to damage
the cassette when tapping it. Do not
touch the exposed tape or allow any
sharp objects near the cassette.
5. Use a cotton swab dipped in
tape head cleaning solution or
denatured alcohol to gently
clean the capstan, pinch roller,
and tape head.
Cleaning the Tape-Handling Parts
Dirt, dust, or particles of the tape’s
coating can accumulate on the tape
heads and other parts that the tape
touches. This can greatly reduce the
cassette player’s performance.
Note: Your local Radio Shack store
sells a complete line of cassette
cleaning kits.
To prevent noise and poor high-fre-
quency response, follow these steps
to clean the cassette player’s tape
handling parts after 20 hours of use.
1. Set FUNCTION to RADIO OFF/
TAPE.
2. Remove the batteries and dis-
connect the AC power cord.

THE FCC WANTS YOU TO KNOW
This equipment complies with the limits for a Class B digital device as specified
in Part 15 of FCC Rules. These limits provide reasonable protection against radio
and TV interference in a residential area. However, your equipment might cause
radio or TV interference even when it is operating properly. To eliminate interfer-
ence, you can try one or more of the following corrective measures:
• Reorient or relocate the radio or TV’s receiving antenna.
• Increase the distance between the CTR-98 and the radio or TV.
• Connect your CTR-98 to an AC outlet that is on a different electrical circuit
from either the radio or TV’s receiver.
Consult your local Radio Shack store if the problem still exists.
