PREPARATION
CONNECTING POWER
You can power the CTR-109 from an y
of three power sources:
• Internal batteries
• Standard AC power (with the supplied power cord)
• Your vehicle’s cigarette-lighter
socket (with an optional DC
adapter)
Note
: Connecting the powe r cord or a
DC adapter disconnects the internal
batteries.
Using Internal Batteries
You can power the CTR-109 from four
C batteries (not supplied). For the best
performance, we recomme nd alkaline
batteries, such as RadioShack Cat.
No. 23-551/651.
2. Install the batteries as indicated
by the polarity symbols (+ and –)
marked inside the compartment.
Cautions:
• Use only fresh batteries of the
required size and recommended type.
• Do not mix old and new batter-
ies, different types of batteries
(standard, alkaline, or rechargeable), or rechargeable
batteries of different capacities.
3. Replace the cover.
When the record indicator becomes
dim, replace the batteries.
Cautions:
• Always dispose of old batteries
promptly and properly.
• Never leave dead, old, or weak
batteries in the CTR-109. They
can leak chemicals and corrode or
damage electronic circuits.

1. Press down on the battery compartment cover and slide it off in
the direction of the arrow on the
cover.
• If you do not plan to use the CTR109 for a week or more, or if you
plan to use an adapter only,
remove the batteries to protect the
CTR-109 from possible battery
leakage.

Using AC Power
To power the CTR-109 from standard
AC power, plug the supplied power
cord into the
the CTR-109. Then plug th e othe r end
into a standard AC outlet.
Cautions:
• Always plug the power cord into
the

unplug the power cord from the
AC outlet before you unplug it
from the
• The power cord has a polarized
plug that is designed to fit into the
recorder’s jack only one way. If the
plug does not easily fit into the
jack, do not force it. Simply turn it
over and try again.

Cautions:
• You must use a DC adapter that
supplies 6 volts and delivers at
least 300 milliamps. Its c enter tip
must be set to negative, and its
plug ,ust correctly fit the CTR109’s
DC IN 6V jack. The recom-
mended adapter meets these
specifications. Using an adapter
that does not could damage the
CTR-109 or the adapter.
• Always plug the adapter into the
CTR-109 before you plug it into
the cigarette-lighter socket, and
always unplug the adapter from
the cigarette-lighter socket before
you unplug it from the CTR-109.

TONE VOLUME
EAR
• 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.
Traffic Safety
Do not wear an earphone while operating a motor vehicle or ridi ng a bicycle.
This can create a traffic hazard and
can be illegal in some areas.
Even though some earphones let yo u
hear some outside sounds when listening at normal volume levels, they
still can present a traffic hazard.
To protect your hearing, follow these
guidelines when you use the earphone.
• Set the volume to the lowest setting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended high volume
listening can lead to permanent
hearing loss.

TAPE TIPS
Recommended Tapes
Tape quality greatly affec ts the qual ity
of the recording. We recommend extended-range or low noise Type 1 regular length (60- or 90 -minute) normalbias cassette tapes. We do not recommend long-play cassette tapes such as
C-120s because they ar e thin and can
easily tangle.
Erasing a Cassette Tape
You can use the tape counter to help
you find specific locations on the tape.
To record over a cassette tape, simply
record as usual. The cassette deck
records over the previous recording.

If you need to erase an entire cassette,
you might prefer using a bulk tape

RadioShack store.
Preventing Accidental
Erasure
Cassette tapes have two erase-protection tabs — one for each side. When a
tab is in place, you ca n reco rd on t hat
side.
To protect a recording from being accidentally recorded over or eras ed, use
a screwdriver to remove one or both of
the cassette tape’s erase-protection
tabs. This prevents
ing pressed.

If you later decide to record on a tape
side after you have removed its eraseprotection tab, plac e a piece of stron g
plastic tape over that side’s erase-protection hole. Be sure you cover only
the hole originally covered by the
erase-protection tab.
A
Caution:
Removing the eras e-protection tabs does not prevent a bulk eraser from erasing a cassette tape.
Restoring Tape Tension and
Sound Quality
After you play a cassette t ape several
times, the tape might become tightly
wound on the reels. This can cause
playback sound quality to deteriorate.
To restore the sound quality, fastforward the tape from the beginning to
the end of one side, then completely
rewind it. Then l oosen the tape reels
by gently tapping each side of the cassette’s outer shell on a flat surface.
Caution
cassette when tapping it. Do not touch
the exposed tape or allow any sharp
objects near the cassette.

MAINTENANCE
Your RadioShack CTR-10 9 AC•DC Portable Cassette Recorde r is an example of
superior design and craftsmanship. The following suggestions will help you care for
your CTR-109 so you can enjoy it for years.
Keep the CTR-109 dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Handle the CTR-109 g ently and carefully. Droppi ng it can damage
circuit boards and cases and can cause the CTR-109 to work improperly.
Use and store the CTR-109 only in normal temperature environments. Temperature extreme s can shorten the life of electron ic devices and distort or melt plastic parts.
Keep the CTR-109 away from dust and dirt, which can cause premature wear of parts.
Wipe the CTR-109 with a d amp c loth oc casion ally to k eep i t lookin g
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the CTR-109.
Modifying or tampering with the CTR-109’s in ternal compo nents can cause a ma lfunction and might inv al idate y ou r C TR -1 09’s warra nty . If yo ur CTR- 109 is no t performing as it should, take it to your local RadioShack store for assistance.

CLEANING THE TAPEHANDLING 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 cause noise and
poor high-frequency response which
can greatly reduce t he cassette player’s performance.
To help keep the cassette player working at its best, clean the cassette player’s tape-handling par ts after ev ery 20
hours of use using a t ape cl eaning kit,
such as Cat. No. 44-1115.
1. Remove the batteries and disconnect any other power source.
2. Open the cassette compartment
cover.
3. Press the erase-protection tab
sensor, then
