field replaceable and can be easily removed with no tools. The battery life is rated up to three years, but
should be replaced if the panel does not maintain date and time during power interruption. It is also

To replace the lithium battery:
1. Depress the two front panel latches towards the center of the panel.
2. Tilt the front panel forward and down.
3. Pull battery out carefully.
4. Ensure that the new battery is the same as the one being replaced.
5. Slide the new battery into place. Be careful to insert the new battery in the correct polarity (not
upside-down; there is a plus (+) sign marked on the battery holder).
AFTER COMPLETING THIS TASK:

powered on, reset the time.
