INSTALLATION

NOTE: If you are installing multiple phones in your 955 system,
you must install and program one set at a time. If more than one
extension is assigned the same extension number, a repeating short ring
(error ring) will sound at all extensions. Reassign extension numbers,
being sure that each extension has a different number from 11 to 22
(see “Assign an Extension Number to Your Phone” in SET UP SYSTEM
FEATURES).

Table/Desk Installation

Install one 9V battery.
•

Press in on the tabs and remove the telephone base.

•

Use a small Phillips head screwdriver to remove the screw
and open the battery door.

•

Insert the 9V battery (included), and replace the screw to
close the battery door.

•

Replace the telephone base.

NOTE: The battery retains telephone memory in the event of a power
failure. If power fails and a working battery is installed, this phone will
work only to dial and answer calls with the handset or headset. No other
features will work until power is restored.

Connect the telephone line cords to the telephone.
