Changing the Battery
The batteries should be changed when the screen
contrast is too light even after adjustment. Before you
replace the batteries, you should have new batteries on
hand.
Warning! If the batteries completely lose power, all the
information stored in the phone list will be permanently
lost. Furthermore, any time that you change the batteries,
you risk losing all user-entered data, so always keep
written copies of your databank information.
