Radio Shack 1250 User Manual

6

You can install an optional 9V backup
battery so if the AC power fails or you
unplug the phone (

 appears), the Sys-

tem 1250 will save the memory numbers
and Caller ID records. We recommend
you use 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 battery.

1. Use a Phillips screwdriver to remove

the battery compartment cover’s
screw on the bottom of the system,
then remove the cover.

2. Place a fresh battery into the com-

partment as indicated by the polarity
symbols (+ and –) marked inside.

3. Replace the cover and secure it with

the screw.

The System 1250 automatically tests
the battery each time it receives a call. If

 appears or the display dims, re-

place the battery.

Important:  You must install the fresh
battery within 2 minutes after removing
the old battery. Otherwise, you might
lose the information stored in the
phone’s memory.

• Always remove old or weak batter-

ies. Batteries can leak chemicals
that can destroy electronic parts.

• Dispose of old batteries promptly

and properly. Do not burn or bury
them.
