nstalling User-Supplied Radio Receivers
Improper installation of radio control equipment may cause the speakers to
malfunction or operate intermittently. Installation must only be performed by
experienced radio technicians who have thoroughly read this manual.
1. TUNING—Tune the radio receiver to the manufacturer’s specifications.
2. POWER—Determine the radio power requirements. The UV control panel provides
+12 Vdc on the RADIO connector on the front panel.

Do not use this voltage source for radios, which draw more than 1.5 A of current in
transmit. Use both grounds and both +12 Vdc connections for current handling. If
a higher current output is required, purchase a 24 to 12 Vdc voltage converter. This
converter is provided with the UVIC series models. Do not use one of the 12 Vdc
batteries to run the radio equipment.
1. AUDIO—Connect the UV controller Receive Audio Input to the de-emphasized
Audio Output of the radio. Use shielded audio grade cable and keep wire runs
as short as possible. The Receive Audio level can vary from 300 mV to 3 V

2. Connect the Transmit Audio Output to the flat (not microphone) input of the radio.
The Transmit Audio Output is adjustable from 100 mV to 3 V

.
3. C.D.—The carrier detect signal from the radio must pull to ground when active. The
radio carrier detect signal is useful for controlling live P.A. When the C.D. signal is
removed from the controller for over 5 seconds, the controller automatically cancels
the P.A. function which eliminates the need to broadcast the cancel tones over the
speakers.
4. PTT—The PTT output pulls to ground when active to key the radio.
5. RX and TX Audio—Adjust the RX and TX Audio levels. See Pre-operational System
Configuration and Testing.
