PREPARATION
CONNECTING POWER
You can power the CTR-107 from any of three power
sources:
• Internal batteries
• Standard AC power (with an optional AC
adapter)
• Your vehicle’s cigarette-lighter socket (with an
optional DC adapter)
Note:
Connecting an adapter disconnects internal
batteries.
Using Internal Batteries
You can power the CTR-107 from four AA batteries
(not supplied). For the best performance, we recommend alkaline batteries, such as RadioShack Cat.
No. 23-557.
You can also use rechargeable nickel-cadmium batteries (Cat. No. 23-125) with a battery charger (Cat.
No. 23-133).
5
14-111 2.fm Page 6 Thursday, July 1, 1999 1:05 PM
Follow these steps to install batteries:
1. Press down on the battery compartment cover
and slide it off in the direction of the arr ows.
2. Install the batteries as indicated by the polarity
symbols (+ and –) marked outside the compartment.
Cautions:
• Use only fresh batteries of the required size
and type.
• Do not mix old and new batteries, different
types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities .
• Always dispose of old batteries promptly and
properly.
6
14-111 2.fm Page 7 Thursday, July 1, 1999 1:05 PM
• Never leave dead, ol d or weak batteries in the
CTR-107. Batteries can leak chemicals and
corrode or damage electronic circuits.
3. Replace the cover.
Notes:
• If you plan not to use the CTR-107 for a week or
more, or you plan to use an AC or DC adapter,
remove the batteries to protect the CTR-107
from possible battery leakage.
• When the RECORD/BATT indicator becomes
dim during operation or does not light when you
turn on the recorder, replace the batteries.
7
14-111 2.fm Page 8 Thursday, July 1, 1999 1:05 PM
Important: Your recorder is capable of using rechargeable nickel-cadmium batteries. At the end of
the batteries’ life, they must be recycled or disposed
of properly. Contact your local, county, or state hazardous waste manageme nt aut horities for infor ma ti on
on recycling or disposal programs i n your area. Some
options that might be available are: municipal curbside collection, drop-off boxes at retailers such as
your local RadioS hack store, recycling collection centers, and mail-back programs.
Using AC Power
To power the CTR-107 from an AC outlet, you need
an AC adapter (not supplied), such as Cat. No. 2731663 or 273-1664.
Cautions:
• The recommended AC adapter supplies 6 volts
and delivers at least 300 millliamps. Its center tip
is set to negative, and its plug correctly fits the
jack on the CTR-107. Using an adaper
DC 6V
that does not meet these specifications could
seriously damage the CTR-107 or the adapter.
8
14-111 2.fm Page 9 Thursday, July 1, 1999 1:05 PM
• Always plug the AC adapter into the CTR-107
before you plug it into the AC outlet, and unplug
the AC adapter from the AC outlet before you
unplug its barrel plug from the CTR-107.
Follow these steps to connect the CTR-107 to AC
power.
1. Set the adapter’s volt age switch to 6V.
2. Insert the adapter’s 5.5 mm outer diameter/2.1
mm inner diameter barrel plug into the adapter’s
cord so it reads –TIP.
3. Insert th e AC adapter’s barrel plug into the
DC 6V
jack on the CTR-107.
4. Plug the AC adapter into a sta ndard AC outlet.

Using Vehicle Battery Power
You can power the CTR-107 from your vehicle’s cigarette-lighter socket using a DC adapter (not supplied),
such as Cat. No. 273-180 2.
Cautions:
• The recommended DC adapter supplies 6 volts
and delivers at least 300 milliamps. Its center tip
is set to negative, and its plug correctly fits the
CTR-107’s

Listening Safely
To protect your hear ing, 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 comfort able level.
• Do not listen at extremely high volume levels.
Extended high volume listening can lead to permanent hearing los s.

14-111 2.fm Page 13 Thursday, Jul y 1, 1999 1:05 P M
• Once you set the volume, do not increase it.
Over time, your ears adapt to the volume l evel,
so a volume le vel that does not cause discomfort
might still damage your hearing.
Traffic Safety
Do not wear the earphone while operating a motor
vehicle or riding a bicycle. This can create a traffic
hazard and is illegal in some areas.
Even though some earphones are designed t o let you
hear some outside sounds when listening at normal
volume levels, they still present a traffic hazard.

TAPE TIPS
Recommended Ta pes
Tape quality greatly affects the quality of the recording. We recommend extended-range or low noise
Type 1 regular length (60- or 90-minute) normal-bias
cassette tapes. We do not recommend long-play cassette tapes such as C-120s because they are thin
and can easily tangle.
Erasing a Cassette Tape
To record over a cassette tape, simply record as usual. The cassette deck records over the previous recording.
To erase the entire cassette tape, insert the supplied
erasing plug into the
MIC
jack and press
RECORD
.
24
14-111 2.fm Page 25 Thursday, Jul y 1, 1999 1:05 P M
If you need to erase an entire cassette, you might
prefer using a bulk tape erase r, availabl e at your loca l
RadioShack store.
Preventing Accidental Erasure
Cassette tapes have two erase-protection tabs —
one for each side. When a tab is in place, you can
record on that si de.
To protect a recording from being accidentally recorded over or erased, use a screwdriver to remove one
or both of the cassette tape’s erase-protection tabs.
This prevents
RECORD
from being pressed.
25
14-111 2.fm Page 26 Thursday, Jul y 1, 1999 1:05 P M
If you later decide to record on a tape side after you
have removed its erase-protection tab, place a piece
of strong plastic tape over the side’s erase-protection
hole. Be sure you cover only the hole originally covered by the erase-protection tab.
Caution: Removing the erase-protection tabs does
not prevent a bulk tape eraser from erasing a cassette tape.
26
14-111 2.fm Page 27 Thursday, Jul y 1, 1999 1:05 P M
Restoring Tape Tension and Sound
Quality
After you play a cassette tape several times, the tape
might become tightly wound on the reels. This can
cause playback sound quality to deter iorate.
To restore the sound quality, fast-forward the tape
from the beginning to the end of one side, then completely rewind it. Then loosen the tape reel s by gently
tapping each side of the cassette’s outer shell on a
flat surface.
Caution:
when tapping it. Do not touch the exposed tape or allow any sharp object s near the cassette.
Be careful not to damage the cassette

MAINTENANCE
Your Optimus CTR-107 Portable Cassette Tape Recorder is an example of superior design and craftsmanship. The following s uggestions will help you care
for your CTR-107 so you can enjoy it for years.
• Keep the CTR-107 dry. If it gets wet, wipe it dry
immediately. Liquids can contain minerals that
corrode electronic circuits.
• Use and store the CTR-107 only in normal temperature environments. Temperature extremes
can shorten the life of electronic devices, damage batteries , and di stort or melt plastic parts.
• Handle the CTR-107 gently and carefully. Dropping it can damage circuit boards and cases and
can cause the CTR-107 to work improperly.
• Keep the CTR-107 away from dust and dirt,
which can cause premature wear of parts.
• Use only fresh batteries of the recommended
size and type. Old batteries can leak chemicals
that can damage your CTR-107’s electronic circuits.
• Wipe the CTR-107 with a damp cloth occasionally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong detergents to clean your CTR-107.
28
14-111 2.fm Page 29 Thursday, Jul y 1, 1999 1:05 P M
Modifying or tampering with the CTR-107’s internal
components can cause a malfunction and might invalidate your CTR-107’s warranty. If your CTR-107 is
not performing as it should, take it to your local RadioShack store for assistance.

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.
To help keep the cassette player working at its best,
clean the cassette player’s tape-handling parts after
every 20 hours of use.
1. Remove the batteries and disconnect any other
power source.
2. Open the cassette compartment cover.
