Battery Installation | AT&T 945 specs

INSTALLATION

If you are installing multiple phones in your telephone 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 26 (see “Assign an Extension Number to Your Phone” on page 21).

Battery Installation

Install a 9V alkaline battery (purchased separately) in order to use some features of this telephone in the event of a power failure. If power fails and a working battery is installed, all four lines of this phone will work only to answer calls with the handset or headset, and to dial calls using the key pad and the One Touch or Redial features. No other features will work until power is restored.

1Remove the wedge from the underside of the base unit. Press on the tabs in the direction of the arrows and pull the wedge away from the phone.

2Remove the battery compartment screw with a small Phillips head screwdriver.
