CHANGING THE BATTERIES
In case the screen clock shows the wrong time after a blackout, change the backup
batteries.
1. Lift the control panel off the mounting screws to remove it from the wall.
2. Remove screws on the back and remove the back cover.
3. Remove the circuit board (CPU card) by gently pulling it up.
4. Remove battery (model CR2032) and place a new battery inside.
5. Place the CPU card in its place in a way that the white arrow points up towards
the top part of the box.
The arrows on both circuit boards must point in the
same direction to avoid circuit board damage.
6. Put the back cover back in.
