the battery cover. Grasp the top edge of the battery and push to the left to remove
the battery from the holder. Lift the battery out and replace with a new battery.
Replace the battery cover, and re-apply power. Using Crimson or the unit’s
keypad, enter the correct time and date.
* Please note that the old battery must be disposed of in a manner that
complies with your local waste regulations. The battery must not be disposed of
in fire, or in a manner whereby it may be damaged and its contents could come
