TR-7730 back up power :

With power supplied from battery, the microprocessor keeps operating even when the power switch is OFF. In this case, current drain is low, approximater 2 mA. For vehicle installation: The car can be parked overnight with little battery power consumed. However, when the car is to be parked for a long period of time (more than 1 month), it is advisable to disconnect the power plug. In this case, the back up function is disabled. If power is diconnected, the back-up function is retained for only 1-1.5 seconds. If instantaneous voltage drop at engine-starting continues for more than 2 seconds, the microprocessor will be reset and the memory cleared.
