PREPARATION

INSTALLING BATTERIES

Your system uses four AAA batteries for power. For the long-
est operation and best performance, we recommend you use
alkaline batteries (Radio Shack Cat. No. 23-555).
The batteries protect the system's memory during power fail-
ures. If you do not connect an AC adapter, the batteries also
power all system functions except message waiting (see
"Connecting an Optional AC Adapter").
Cautions:
• Use only fresh batteries of the recommended size and
type.
• When you replace the batteries, have fresh batteries on
hand before you begin. You must install fresh batteries
within 2 minutes after removing the old batteries. Other-
wise, you might lose the information stored in the sys-
tem.
• When you replace the batteries, do not press any but-
tons on the system after you remove the old batteries.
Doing so might erase all stored information from the sys-
tem.
• Never leave dead or weak batteries in the system.
• Dispose of old batteries promptly; do not bury or burn
them.
