Every time the radio is turned on, it performs a functional self-check and if necessary, will sound a 5 second warning tone unlike the chirp tone nor- mally heard at power-up. This is an indication that the radio is no longer operating at the exact parameters set in the factory or by a Motorola Radius dealer and should be serviced immediately.

Service

Because this unit contains a radio transmitter, most local governments prohibit anyone from making any internal adjustments to the transmitter unless specifically licensed to do so by government regulations. If your radio fails to operate or any operational difficulties should arise, contact your local Motorola Radius dealer.

Proper repair and maintenance procedures will assure efficient operation and long life for this radio.
