INTRODUCTION

Your RadioShack Personal FM Radio is a light- weight, 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 ra- dio.

Your radio has auto-squelch, which means you won’t hear anything on the channel unless someone is transmitting nearby on the same channel. But, you can turn off auto-squelch to hear weaker, distant transmissions (see Page 11).

Also, if you do not transmit for over 30 seconds, the radio automatically switches to a power save mode and returns to full power when it receives a transmis- sion or you press any key.

We recommend you record your radio’s serial number here. The number is on the radio’s back panel.
