CONTROLS & INDICATORS

 

 

Power LED: 

This red LED indicates that power is applied to the unit through the rear connector. 

 

Transmit LED: 

This red LED indicates that the unit is applying push to talk to the base station or repeater. 

 

COR/MON LED:

 This red LED indicates when a monitor output is turning off the CTCSS/DCS and monitoring the 

standard carrier squelch or that carrier is detected on the base station radio. 
 

Tone LED:

 This red LED indicates presence of low-level guard tone. 

 

F1-F2 LEDs: 

The red F1 and F2 LED’s indicate which channel select output is active.
