Страница: 6 / 31

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.
Installing The Back-Up Battery
1. Turn the unit upside down on a soft surface such as a cloth or towel to avoid
scratching the front cabinet surface.
2. Open the battery compartment cover as shown in the illustration.
3. Insert two fresh “AAA”(UM-4) batteries into the battery compartment. We
recommend that you use a well-known brand of alkaline batteries for longest life
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.
4. Replace the battery compartment cover and turn the unit right side up.
Replacing The Back-Up Battery
When it’s time to replace the battery the Low Battery lcon( ) will be shown in the
lower right corner of the display. Insert two fresh “AAA”(UM-4) batteries following the
same procedure described above, however leave the unit connected to the AC
adaptor while replacing the battery to avoid losing all of your settings.
