Backup batteries installation and use
In the event of a power failure, your telephone can still operate with limited
functions if there are backup batteries (purchased separately) installed in the
telephone base. If a power failure happens during a call on the corded handset,
the call continues (at the lowest volume) until you hang up; while a call on the
cordless handset or speakerphone disconnects immediately.
During a power failure, you can still make and answer calls using the corded
handset. However, you cannot make or answer calls on the cordless handset or
speakerphone.
If power resumes while you are on a call, the call continues and the telephone
resets once you hang up.
Follow the steps below to install backup batteries.
2. Press the tab on the base battery
cover (on the bottom of the
telephone base) toward the cover
and swing open the battery door.
3. Insert three new AAA alkaline
batteries, matching the + and
- signs engraved on the telephone
base.
4. Replace the backup battery cover
onto the telephone base; the
cover clicks into place when it is
attached properly.
During a power failure, if the backup batteries are installed, the telephone
base displays CHECK AC POWER.
1. Make sure the telephone line cord
and power adapter cord are not
connected to the telephone base.
NOTES:
1. With backup batteries, the base ringer and the handset listening volume will be at the lowest setting.
2. We recommend changing the batteries every nine months.
