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.
