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
1 Turn the radio on and select
the desired zone and
channel.
2 Listen for a transmission.
3 Adjust the Volume Control
knob if necessary.
4 Press and hold the PTT
button to transmit. The LED
lights RED while
transmitting.
5 Release the PTT button to
receive (listen).
