Resetting the Tuner
Each time the tuner is powered off, the microprocessor saves all memories and configurations to non-
volatile memory ready to be used the next time the unit is turned on and transmit power is applied. If the
tuner is not working properly, even on initial power on, try resetting to the factory defaults.
