The Tlkr-t42 has 16 channels. To communicate with another radio, both radios must be set to the same channel.

• To Receive: Release the PTT button. The radio is now in receive mode.

Important: Only one person can talk at a time on a channel. Wait for the other party to finish speaking before pressing PTT.

4.4. Call Tone

To send an audible alert to other radios on the same channel, briefly press the Call Tone button (music note icon). This is useful for getting someone's attention before speaking.
