1-1840.fm Page 2 Thursday, August 5, 1999 3:15 PM INTRODUCTION Your RadioShack Personal FM Radio is a lightweight, palm-sized radio that you can clip to your belt and carry almost anywhere. You can use it to talk with another person who has an FRS radio set to the same frequency (14-channel selectable) as your radio. Your radio has auto-squelch, which means you won’t hear anything on the channel unless someone is transmitting nearby on the same channel.
21-1840.fm Page 3 Thursday, August 5, 1999 3:15 PM PREPARATION INSTALLING BATTERIES Your radio uses three AA batteries for power. For the longest life, we recommend alkaline batteries (available from your local RadioShack store). You can also use rechargeable nickel-cadmium batteries (such as Cat. No. 23-325) and recharge them in the radio using an optional AC adapter (such as Cat. No. 2731663). Follow these steps to install batteries. ALKALINE/ Ni-Cd 1.
