Your Optimus CTR-116 Voice-Activated Cassette Tape Recorder uses the latest in recording technology to make recording easy and convenient. Recording begins when the CTR-116
detects sound and ends when sound subsides, for hands-free
operation. The CTR-116’s microphone is sensitive enough for
the boardroom, a seminar, or a lecture hall.
The CTR-116’s features include:
Voice-Activated (VOX) Recording
— records only when there
is sound so that you c an sa ve pow er and preven t blank sect ion s
of tape.
Upright Style
— lets you view the ca ss ett e deck as it plays and
— you can power the recorder from internal batteries, or from a vehicle’s cigarette-lighter socket or
standard AC power (using the appropriate optional adapter).
We recommend you record the CTR-116’s serial number here.
The number is in the recorder’s battery compartment.
You can operate your CTR-116 from any of these power sources:
• four AA batteries (not supplied)
• standard AC power (using an optional AC adapter)
• vehicle battery power (using an optional DC adapter)
Note:
Using an adapter automatically disconnects the internal
batteries.
Installing Batteries
You can power the CTR-116 with four AA batteries. For the
longest life, we recommend alkaline batteries. Or, you can use
rechargeable nickel-cadmium batteries (RadioShack Cat. No.
23-325) and charge them with a battery charger, such as Cat.
No. 23-242.
Cautions:
• Use only fresh batteries of the required size and recom-

batteries of different capacities.

Cautions:
• Always remove old or weak batteries. Batteries can leak
chemicals that can destroy electronic parts.

• Dispose of old batteries promptly and properly. Do not burn
or bury them.
Note:
At the end of a Ni-Cd rechargeable battery’s useful life, it
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 curb-side
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 CTR-116 from an AC outlet, you need an AC
adapter, such as Cat. No. 273-1454.
Cautions:
• The recommended adapter supplies 6 volts DC power and
delivers at least 150 milliamps. The adapter’s center tip
must be set to negative, and its plug must properly fit the

Listening Safely
To protect your hearing, follow these guidelines when you use
the earpho ne.
• Do not listen at extremely high volume levels. Extended
high-volume listening can lead to permanent hearing loss.
10
14-1122.fm Page 11 Wednesday, May 17, 2000 9:55 AM
• Set the volume to its lowest level before you begin listening. After you put on the earphone, adjust the volume to a
comfortable listeni ng lev el .
• 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 the earphone while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and could be illegal in some areas.
Even though some earphones let you hear some outside
sounds when listening at normal volume levels, they still can
present a traffic hazard.

RECORDING
Note:
For the best performance, use only regular length (60- or
90-minute) cassette tapes. We do not recommend long-playing
cassette tapes, such as C-120s, because they are extremely
thin and can tangle easily.
VOX RECORDING
When you select
VOX
recording, the CTR-116 automatically begins recording when it senses a voice or other sound, and automatically stops when the sound stops.
For the best recording quality, place the recorder about 1 foot
from the sound source. Because the microphone is so sensitive, it will also pick up a voice or group of voices (such as an
audience) from several feet away.

Or, you can quickly erase both sides of a cassette tape using a
bulk tape eraser, available at your local RadioShack store.
PREVENTING ACCIDENTAL ERASURE
Cassettes have two erase-protection tabs — one for each side.
When a side’s tab is in place, you can record on that side.
21
14-1122.fm Page 22 Wednesday, May 17, 2000 9:55 AM
To prevent accidental erasure of a tape recording, use a screwdriver to remove one or both of the cassette tape’s eraseprotection tabs. This prevents
RECORD
from being pressed.
If you later decid e to record on a tape side afte r you have removed its 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.

Caution:
Removing the erase-protection tabs does not prevent
a bulk tape eraser from erasing a cassette tape.

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:

CARE AND MAINTENANCE
To enjoy your CTR-116 for a long time:
• Keep the CTR-116 dry. If it gets wet, wipe it dry immediately.
• Use and store the CTR-116 only in normal temperature
environments.
• Handle the CTR-116 gently and carefully. Don’t drop it.
• Keep the CTR-116 away from dust and dirt.
• Wipe the CTR-116 with a damp clot h occas ionall y t o keep it

Modifying or tampering with th e CTR-11 6’s in ternal c ompon ents
can cause a malfunction and invalidate its warranty. If your
CTR-116 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 the tape touches. This can
greatly redu ce the perform ance of the casset te recorder. A fter
every 20 hours of tape player operation, use a cassette deck
cleaning kit (Cat. No. 44-1202) or follow these steps to clean
the tape-handling parts.
1. Remove the batteries and disconnect any other power
source.
