Back-up Battery
Before replacing the back-up battery, note the following precautions:

• Be sure to replace the back-up battery at least once every five years. Otherwise, you run the risk of
losing data stored in memory.
1. Press OFF to switch power OFF.
2. Remove the screws that hold the back-up battery compartment cover in place, and remove the cover.
3. Insert a thin, pointed object into (A) and remove the old battery.
RESET OPERATION
1. Press ON to switch power ON.

the data before you continue!
3. Remove both old batteries and replace them with two new ones.
• Make sure that the positive (+) and negative (-) ends are facing correctly.
4. Replace the holder.
5. Turn on power.
• The Home Time screen always appears whenever you turn power on for the first time after replacing
batteries.
