•Set it to ALKALINE before you con- nect an external power source (vehi- cle battery power or AC adapter) to the POWER jack or while you are us- ing internal batteries (alkaline or re- chargeable).

•Set it to NI-CDonly when you con- nect a battery charger to the POWER jack to charge the installed recharge- able batteries.

Warning: To avoid injuring yourself or damaging the TRC-237, connect a bat- tery charger to the POWER jack only when nickel-cadmium batteries are in- stalled (see “Recharging Nickel-Cadmium Batteries” on Page 10). Never try to re- charge non-rechargeable batteries. They could get very hot and explode.

Note: You can connect an external pow- er source for power regardless of the type of batteries you installed.

USING BATTERIES

You can power the TRC-237 from eight

AAalkaline batteries (such as Ra- dioShack Cat. No. 23-552) with the two supplied dummy batteries, or 10 re- chargeable AA nickel-cadmium batteries (such as Cat. No. 23-125).
