Battery Back-Up System - Sanyo DMP-P690 Instruction Manual

This system includes a battery back-up circuit that will maintain the time and alarm
settings, and the preset tuner memories, in the event of a temporary power
interruption. The battery back-up system requires two "AAA"(UM-4) batteries(not
included). If the back-up battery is not installed, or the battery is exhausted, and the
AC power supply is interrupted, the time, alarm, and preset memory stations will be
lost. It will be necessary to reset the unit when the power is restored.
The battery back-up compartment is located on the bottom cabinet.

and best performance. Be sure to follow the polarity (+/-) markings inside the
battery compartment. If the batteries are inserted incorrectly the battery back-up
system will not work.
