ASTRO XTS 5000 Model II 27
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).
