5.2. Channel Selection
- The Retevis RT27 has 22 available channels.
- To change the channel, rotate the Channel selection knob (second knob from the top) to your desired channel number. The radio will announce the selected channel.
- Ensure all radios in your group are set to the same channel for communication.
5.3. Push-to-Talk (PTT) Button
- To transmit, press and hold the PTT (Push-to-Talk) button located on the side of the radio.
- Speak clearly into the microphone, which is located near the PTT button.
- Release the PTT button to stop transmitting and listen for a response.
5.4. VOX Hands-Free Operation
The VOX (Voice Operated Exchange) function allows you to transmit without pressing the PTT button, by simply speaking into the microphone.
- To activate or deactivate VOX, refer to the specific programming instructions or use the side keys if configured for this function.
- The VOX sensitivity can be adjusted from level 0 (off) to 9 (most sensitive). Higher sensitivity means the radio will transmit with softer voice input.
- When VOX is active, the radio will automatically transmit when it detects your voice and stop transmitting when you stop speaking.
