Charging a spare battery
An optional spare battery (AT&T model 103, sold separately) can be kept charged in the base for quick replacement when a handset battery becomes depleted and for power failure operation.
A spare battery requires at least 24 hours to reach full charge.
Caution: Only the rechargeable handset battery (AT&T model 102) or optional replacement battery (AT&T model 103) can be charged in the base.
Press latch on side of phone to open drawer, insert battery, then close drawer.
Insert battery with contacts facing up and to the right, as shown.
Power failure operation
In the event of a power failure, a fully charged spare battery in the base will allow you to make and receive calls on the base as well as the system’s cordless handset(s) for 30 to 60 minutes, depending on usage.
In power failure mode, the SPARE BATTERY indicator on the base will flash. You will see CHECK AC POWER in the display and a P will appear in the upper left corner of the display.
NOTE: In power failure mode, the base speakerphone volume will be at the lowest level and cannot be adjusted. Also, the base display does not light.
