Should there be a power failure, you can still use your telephone. However,
the flashing light will not work.
If you would like to use the telephone during a power failure, you can put
4 batteries (Alkaline 1.5V AA) into the telephone.

even if you have put in batteries.

will appear in the display if the batteries
are dead.
