Memory Backup Battery

A 3V lithium battery has already been installed in your phone to act as a backup when the AA-size batteries lose their power. The 3V lithium battery ensures that the numbers you’ve stored in memory will be retained when the AA-size batteries are removed or aren’t working properly. You’ll know you need to replace the 3V lithium backup battery if memory backup fails when you remove the AA-size batteries. To replace the 3V lithium battery:

1.Disconnect the telephone line cord from the LINE jack on the back of the phone.

2.Remove the plastic cover with a screwdriver to expose the black battery holder.

3.Use the screwdriver again to pop up either end of the black battery holder out of the cabinet.

4.Slide the battery holder out of the compartment and remove the battery from the black holder.

5.Insert new battery and snap into the black holder making sure you’ve matched the + and

– polarities on the battery and the holder.

6.Replace the battery holder and make sure that the keyhole on the holder lines up with the tab on the cabinet.

7.Replace the plastic cover and plug the telephone line cord back into the phone.
