Before you remove the battery from the holder, make sure that the replacement battery is within reach,
as the
Control Board must not be without battery power for more than 30 seconds
.
Otherwise, all firmware and the setup data will be erased. *
Remove the battery from the holder using a small insulated screwdriver to push out the battery,
direction indicated by the red arrows and insert the new battery in the direction of the green arrow.
Mount the control board on the interface board again by gently pressing the PCB to its rest on the
Interface Board. Make sure that all 4 corners are fully pressed towards the Interface Board.
Switch on the unit via the input switch Q1 and close the door. The unit now passes through the
initialization test and goes into standby mode.
Enter the setup menu and select menu item “Battery Replaced” to confirm new battery installation.

Important Note!
If the blue LED on the Control Board (location can be found on the Fig. 8.1.1) flashes with
approximate 2 flashes per second and the display reports “Communication Error”, the firmware
on the Control Board has been erased. The Control Board must be sent to ITW GSE to be
reloaded.
