CONNECTING AN OPTIONAL
AC ADAPTER
If you subscribe to a message waiting service, you need an
AC adapter (such as Cat. No. 273-1455, not supplied) to pow-
er the system.
Note: You must also keep fresh batteries in the system to pro-
tect the information stored in memory during power failures.
Cautions:
• You must use an AC adapter that supplies 9 volts DC
and at least 50 milliamps. Its center tip must be set to
negative, and its plug must correctly fit the system's
jack. The recommended adapter meets these specifi-
9V
cations. Using an adapter that does not meet these
specifications could damage the system or the adapter.
• Always connect the AC adapter to the system before you
plug it into the AC outlet, and unplug the adapter from
the AC outlet before you unplug it from the system.
