Inserting the Backup Batteries
To avoid having to adjust the device settings again after a power failure or
the device being disconnecting from the mains, you can use backup
batteries (not supplied). Proceed as follows:
 Disconnect the device from the mains.
 Open the battery compartment [14] on the bottom of the device.
 Insert two AAA batteries into the battery compartment, making sure
the polarity is correct. Note the + and – icons on the batteries and
inside the battery compartment (see diagram).
 Close the battery compartment.
 Reconnect the device to the mains.
Remove the batteries when the device is not to be used
for an extended period.
