Squelch LEDs.
•Blue (On) = Transmitter signal detected
•Off = no signal or signal squelched because of poor reception or no tonekey
NOTE: The receiver will not output audio unless at least one blue LED is illuminated.
RF LEDs. Indicate RF signal strength from the transmitter at each antenna and diversity condition.
•Amber = normal
•Red = overload (greater than
Audio LEDs. Indicate audio signal strength from transmitter.
•Green = signal present
•Yellow = normal peak
•Red = overload
To correct this level, adjust the transmitter gain.
Indicates the name and range of receiver frequency band.
LCD Interface. Provides a convenient way to program the receiver from the front panel (see detail on next page).

Diversity antenna inputs A and B.
Note: Antenna inputs are DC biased. Use only antenna combiners and accessories listed in page 19. Some types of antenna splitters or other products may short the DC power and damage the receiver.
Mic/Line switch. Changes output level
Electrically balanced XLR output jack
Lift/GND switch. Lifts ground from Pin 1 of the XLR connec- tor (default = GND).
Impedance balanced 1/4” output jack (200:)
