INSTALLING THE SYSTEM

INSTALLING A BACKUP
BATTERY IN THE
CONSOLE
If AC power fails or you unplug the con-
sole, a 9V backup battery (not supplied)
saves all of the information stored in the
console's memory. To provide at least
12 hours of backup time, we recom-
mend an alkaline battery such as Ra-
dioShack Cat. No. 23-553.
Caution: Use only a fresh battery of the
required size and recommended type.
Follow these steps to install a backup
battery.
1. Slide the battery compartment cover
in the direction of the arrow to
remove it.

2. Snap the battery's contacts firmly to
the battery connector and place the
battery into the compartment.
3. Replace the cover.
Replace the battery at least once each
year or when the BATTERY LOW indi-
cator on the console lights.
Note: To avoid losing stored informa-
tion, do not unplug the console from AC
power while you replace the battery.
Cautions:
• Always remove an old or weak bat-
tery. Batteries can leak chemicals
that can destroy electronic parts.
• Dispose of old batteries promptly
and properly. Do not burn or bury
them.
