FEATURES
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

PREPARATION
POWERING THE CTR-116
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:
• Always remove old or weak batteries. Batteries can leak
chemicals that can destroy electronic parts.

14-1122.fm Page 7 Wednesday, May 17, 2000 9:55 AM
• 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
