General Radio Operation

Receive / Transmit

Radio users who switch from analog to digital radios often assume that the lack of static on a digital channel is an indication that the radio is not working properly. This is not the case. Digital technology quiets the transmission by removing the “noise” from the signal and allowing only the clear voice or data information to be heard.

This section emphasizes the importance of knowing how to monitor a channel for traffic before keying-up to send a transmission.

Without Using the Volume Set and Monitor Buttons

1Turn the radio on and select the desired zone and channel.

2Listen for a transmission.

3Adjust the Volume Control knob if necessary.

4Press and hold the PTT button to transmit. The LED lights RED while transmitting.

5Release the PTT button to receive (listen).
