6.2 Configuration and Reconfiguration of the System
After changing the setting on the SIP switches the radio requires reprogramming. This is
done automatically through the microprocessor; however it is vital that the microprocessor
completes its work prior to connecting inputs and outputs or modifications to the system.
This can be visually observed when MC LED changes from solid on to normal status (blink
faster and weakly). Any interference during this operation could cause the radio to be
programmed incorrectly which will result in the permanent failure of the radio.
Any incorrect setting of Channel, Address or VID will be reported by the MC LED. It’ll be
appeared by the pulsed on.
