VIII.2 Change the battery
This operation requires good knowledge about the DES (electrostatic discharges and wearing a bracelet or any other
earthing accessory
When the Low battery alarm appears and the red indicator lights up, this means that the emergency battery for memory
and real-time clock back-up is too weak. The procedure for changing the battery is described below. A condenser is
used to back-up the memory and to operate the clock for about 10 minutes after the current has been dut. If the battery
change operation takes less than 10 minutes, there is no need to reload the schedule and the clock continues to func-
tion nromally.
The spare battery is of CR2032 type.
Press on the clips on each side of the box with a small screwdriver to detach the base cover. Hold the base and remove
the cover
Placing the battery
Take the battery and slowly pull upwards until the battery has left its housing.
Take a new battery and slide it in the housing. Take care to house the battery in the correct
direction to match with the polarity.
