NOTE
Before the initial start-up of the device, please insert the backup battery fi rst (as
described in the following), as otherwise any data stored would be lost in the
event of power failure.
CAUTION
Caution: danger of explosion if battery is replaced incorrectly.
Inserting or replacing the backup battery (see image):
1. Disconnect the device from the power supply.
2. Remove the upper housing cover (frame) using a suitable tool (e.g. a small
screwdriver).
3. Remove the front cover.
4. To replace it, remove the empty battery from the clamp pressing slightly
against the contact spring using pliers.
Caution! To avoid a short circuit, the tips of the pliers have to be insulated.
5. Press the new battery lightly against the contact spring and into the clamp-
ing bracket until it clicks into place. Ensure correct polarity!
6. Put the front cover back into place.
7. Put the device frame back into place and push until it clicks into place.
8. Reconnect the device to the power supply.
NOTE
As there is no power supply if the battery is empty or removed, not only the
stored data are lost but also the time is no longer correct. In this case, the time
has to be reset in visual energy with the corresponding command (see section
"Setting time and date" in the user manual).
