UR4D AND UR4S FRONT AND REAR PANELS Receiver Controls and Connectors 1. SYNC Infrared (IR) port. Transmits group, channel, and other settings to a transmitter. 2. 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. 3. RF LEDs. Indicate RF signal strength from the transmitter at each antenna and diversity condition. · Amber = normal · Red = overload (greater than ­25 dBm) 4. Audio LEDs. Indicate audio signal strength from transmitter. · Green = signal present · Yellow = normal peak · Red = overload To correct this level, adjust the transmitter gain. 5. Indicates the name and range of receiver frequency band. 6. LCD Interface. Pr
