PREPARATION

POWERING THE CTR-116

You can operate your CTR-116from 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-116with four AA batteries. For the longest life, we recommend alkaline batteries. Or, you can use rechargeablenickel-cadmiumbatteries (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 recommended type.

Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

Dispose of old batteries promptly and properly. Do not burn or bury them.

Note: At the end of aNi-Cdrechargeable 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: municipalcurb-sidecollection,drop-offboxes at retailers such as your local RadioShack store, recycling collection centers, andmail-backprograms.

Using AC Power

To power the CTR-116from 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 CTR-116’sDC 6V jack. Using an adapter that does not meet these specifications could damage theCTR-116or the adapter.

Be sure you connect the adapter to the CTR-116before you plug it into the AC outlet, and unplug the adapter from the AC outlet before you unplug it from theCTR-116.
