The power supply for the ECU controller circuit board is back-up by a 9V battery.  During

an ac power failure, the battery will maintain the transmitter operating configuration

stored in the controller logic circuitry.  Once power is returned to the transmitter, the

transmitter will automatically resume operation in the configuration appearing prior to

the ac failure.  If an extended ac power failure occurs, the transmitter will be operated to

off by an ac loss/auto shutdown circuit on the controller circuit board.
