Appendix B
Optional spare battery (purchased separately)
Install a 9V alkaline battery (purchased separately) 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, and to dial calls using the dial pad and the one touch or
redial features. No other features will work until AC power is restored.
After your set has an extension number, you can unplug the telephone line
and install a spare battery.
NOTES:
• Use disposable alkaline batteries only. Do not use rechargeable batteries.
• When there is AC power and there is no spare battery or the spare battery
is low, the screen will show LOW BATT.
1. Unplug all telephone line cords from this set.
2. Press on the tabs in the direction of the arrows and pull the bracket away
from the telephone base.
3. Remove the battery compartment screw with a Phillips screwdriver.
4. Press as shown in the picture and then pull out the battery door.
