FEATURES
Your Optimus CTR–113 Voice-Activated Cassette Tape
Recorder gives you convenient recording technology.
You can have recording begin and end according to the
sound level in a room, which gives you hands-free operation while recording.
Because the CTR-113 does not record long periods of silence, you not only save tape space and battery power,
you also save time when you try to find a certain section
on the tape. Your recorder is small enough to fit in a briefcase or purse, so you can take it almost anywhere.
The cassette recorder includes these special features:
Semi Auto Stop — during playback and recording, stops
the recorder and releases the tape mechanism when the
tape reaches the end, to save battery power and protect
your cassette tape.
Digital Tape Counter — helps you quickly return to a
specific section on the tape.
One-Touch Recording — lets you press one button to
start recording.

PREPARATION
POWERING THE RECORDER
For portable use, you can power the recorder from internal batteries. Using adapters, you can also power it from
a standard AC outlet or your vehicle’s cigarette-lighter
socket.
Using Internal Battery Power
The recorder uses two AA batteries (not supplied). For
the best results, we recommend alkaline batteries, such
as RadioShack Cat. No. 23-552. Or, you can use rechargeable nickel-cadmium batteries, such as Cat. No.
23-125, with a battery charger (Cat. No. 23-133).
Cautions:
• Use only fresh batteries of the recommended size
and type.
• Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different capacities.
5
14-1119.fm Page 6 Friday, July 2, 1999 3:28 PM
Follow these steps to install batteries.
(illus — show the removal
of batt. compartment cover
and installation of batteries.)
1. Slide the battery compartment cover in the direction
shown by the arrow on the cover.
Caution: The battery compartment cover is hinged.
Do not try to remove it.
2. Install two AA batteries as indicated by the polarity
symbols (+ and –) marked on the back of the
recorder.
3. Replace the cover.
When the recorder stops operating properly or the battery
light is low, replace the batteries.
Cautions:
• If you do not plan to use the recorder for a week or
more, or you plan to use only another power source,
remove the batteries.
• Always dispose of old batteries promptly and properly.
6
14-1119.fm Page 7 Friday, July 2, 1999 3:28 PM
Important: Your recorder is capable of using rechargeable nickel-cadmium batteries. At the end of the batteries’
lives, they must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or
disposal programs in your area. Some options that might
be available are: municipal curbside collection, drop-off
boxes at retailers such as your local RadioShack store,
recycling collection centers, and mail-back programs.
Using AC Power
To power the recorder from an AC outlet, you need an
AC adapter (not supplied), such as Cat. No. 273-1654.
Cautions:
• You must use an adapter that supplies at least 3 volts
and delivers at least 300 mA. Its center tip must be
set to negative, and its barrel plug must fit the CTR113’s DC 3V jack. The recommended adapter meets
these specifications. Using an adapter that does not
meet these specifications could damage the CTR113 or the adapter.
• Connecting an AC adapter automatically disconnects
internal batteries.
7
14-1119.fm Page 8 Friday, July 2, 1999 3:28 PM
• Always plug the adapter into the recorder before you
plug it into the AC outlet. Always unplug the adapter
from the AC outlet before you unplug it from the
recorder.
Illust.
1. Set the adapter’s voltage switch to 3V.
2. Attach the 3.4 mm outer diameter/1.3 mm inner
diameter barrel plug to the AC adapter’s cord with the
tip set to negative (–).
3. Insert the barrel plug into the recorder’s DC 3V jack.
4. Plug the adapter into a standard AC outlet.
Using DC Power
To power the recorder from your vehicle’s cigarette-lighter
socket, you need a DC adapter (not supplied), such as
Cat. No. 273-1810 or Cat. No. 270-1560.
8
14-1119.fm Page 9 Friday, July 2, 1999 3:28 PM
Cautions:
• You must use an adapter that supplies 3 volts and
delivers at least 300 milliamps. Its center tip must be
set to negative, and its barrel plug must fit the CTR113’s DC 3V jack. The recommended adapter meets
these specifications. Using an adapter that does not
meet these specifications could damage the CTR113 or the adapter.
• Connecting a DC adapter automatically disconnects
internal batteries.
• Always plug the adapter into the recorder before you
plug it into the cigarette-lighter socket. Always unplug
the adapter from the cigarette-lighter socket before
you unplug it from the recorder.
Follow these steps to power the recorder from your vehicle’s cigarette-lighter socket.
Illust.
1. Set the adapter’s voltage switch to 3V.
9
14-1119.fm Page 10 Friday, July 2, 1999 3:28 PM
2. Attach the 3.4 mm outer diameter/1.3 mm inner
diameter barrel plug to the DC adapter’s cord with
the tip set to negative (–).
3. Insert the barrel plug into the recorder’s DC 3V jack.
4. Plug the other end of the adapter into the vehicle’s
cigarette-lighter socket.
Note: If the recorder does not operate properly when
powered from your vehicle’s battery, unplug the adapter
from the cigarette-lighter socket and clean the socket to
remove any ashes or other debris.
USING THE EARPHONE
You can use the supplied earphone for private listening.
Insert the earphone’s 1/8-inch (3.5-mm) plug into the EAR
jack.
Illust.
Note: Connecting the earphone disconnects the recorder’s built-in speaker.
10
14-1119.fm Page 11 Friday, July 2, 1999 3:28 PM
Listening Safely
To protect your hearing, follow these guidelines when
you use an earphone.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to permanent hearing loss.
• Set the volume to its lowest level before you begin
listening. After you put on the earphone, adjust the
volume to a comfortable listening level.
• Do not increase the volume once you have established a comfortable listening level. 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 riding a bicycle. This can cause a traffic hazard and
could be illegal in some areas.
Even though some earphones let you hear outside
sounds when listening at normal volume levels, they still
can present a traffic hazard.

OPERATION
LOADING A CASSETTE TAPE
1. Take up any slack in the cassette tape by turning the
hub with a pencil to prevent the tape from becoming
tangled in the tape mechanism. Do not touch the
tape.
Illust.
2. Open the cassette compartment door by lifting it at
the notch. Insert a cassette tape into the door guides
so the cassette’s open edge faces out, the side you

RECORDING
Notes:
• We recommend you use normal bias (Type I) cassette tapes, such as RadioShack LN and XR tape.
• We recommend regular length (60- or 90-minute)
cassette tapes. We do not recommend long-play cassette tapes, such as C-120s, because they are thin
and can easily tangle.
• The ALC (automatic level control) circuit automatically sets the recording level. VOLUME has no effect.
• For the best quality recordings, place the recorder 1
to 5 feet from the sound source.
RECORD after you
Caution: Never try to force down

Illust.
TAPE TIPS
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 deteriorate.
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 reels by gently tapping each
side of the cassette’s outer shell on a flat surface.
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.
17
14-1119.fm Page 18 Friday, July 2, 1999 3:28 PM
Erasing a Cassette Tape
To record over a cassette tape, simply record as usual.
The cassette deck records over the previous recording.
You can quickly erase both sides of a cassette tape using
a bulk tape eraser, such as Cat. No. 44-232.
Preventing Accidental Erasure
Cassette tapes have two eraseprotection tabs — one for each
side. When a tab is in place, you
can record on that side. 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.
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
18
14-1119.fm Page 19 Friday, July 2, 1999 3:28 PM
sure you cover only the hole originally covered by the
erase-protection tab.
Illust.
Caution: Removing the erase-protection tabs does not
prevent a bulk eraser from erasing a cassette tape.

MAINTENANCE
Your CTR-113 Voice-Activated Cassette Tape Recorder
is an example of superior design and craftsmanship. The
following suggestions will help you care for your recorder
so you can enjoy it for years.
Keep the recorder dry. If it gets wet, wipe it
dry immediately. Liquids might contain
minerals that can corrode the electronic circuits.
Use and store the recorder only in normal
temperature environments. Temperature
extremes can shorten the life of electronic
devices, damage batteries, and distort or
melt plastic parts.
Keep the recorder away from dust and dirt,
which can cause premature wear of parts.
Handle the recorder gently and carefully.
Dropping it can damage circuit boards and
cases and can cause the recorder to work
improperly.
20
14-1119.fm Page 21 Friday, July 2, 1999 3:28 PM
Use only fresh batteries of the required
size and type. Batteries can leak chemicals
that damage your recorder’s electronic
parts.
Wipe the recorder with a damp cloth occasionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or
strong detergents to clean the recorder.
Modifying or tampering with the recorder’s internal parts
can cause a malfunction and might invalidate its warranty. If your recorder is not operating 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 performance of the
cassette recorder. To prevent noise and poor high-frequency response, clean the cassette recorder’s tapehandling parts after about 20 hours of use. Use a cassette deck cleaning kit (Cat. No. 44-1202) or follow these
steps to clean the tape-handling parts.
21
14-1119.fm Page 22 Friday, July 2, 1999 3:28 PM
1. Remove the batteries and disconnect any other
power source.
2. Open the cassette compartment door.
3. Hold down the erase protection tab sensor, then
press RECORD to expose the tape-handling parts.
4. Use a cotton swab dipped in denatured alcohol or
tape head-cleaning solution to clean the record/play
head, pinch roller, capstan, erase head, and tape
guides.
Illust.
5. When you finish cleaning, press STOP and close the
compartment. Then reconnect power.
