Flexible Antenna with BNC Connector

provides excellent reception and trans- mission, and is designed to help prevent antenna breakage.

Automatic Display Dimmer — the chan- nel display automatically brightens when you press most buttons. Then, after a few seconds, it dims to save battery power.

Power/Charging Jack — lets you power your TRC-237 from an AC or DC power source, so you can use the TRC-237 with- out draining the batteries. And, lets you charge nickel-cadmium batteries without removing them from the TRC-237.

Note: You need eight AA alkaline batter- ies or ten nickel-cadmium rechargeable batteries (not supplied) to power your TRC-237.

We recommend you record the TRC- 237’s serial number here. The serial number is located on the radio’s back panel:
