14-1119.fm Page 2 Friday, July 2, 1999 3:28 PM 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.

14-1119.fm Page 5 Friday, July 2, 1999 3:28 PM 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.
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.

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.
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.

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.

14-1119.fm Page 13 Friday, July 2, 1999 3:28 PM 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.
