UMG 96RM-E
Replacing the battery
If the battery capacity is shown as < 75 %, we
recommend that the battery be replaced.
Procedure
1. Disconnect system and device from power supply
before beginning work.
2. Discharge any electrostatic charge in your body,
e. g. by touching an earthed cabinet or metal part
(radiator) connected to the earth of the building.
3. Remove the battery from the battery compartment,
—e.g. using long-nose pliers—. The device does
not need to be opened to do this as the battery
compartment can be accessed from the outside
(see figure on the right).
4. Make sure that the polarity is as shown
on the insertion opening of the battery compartment
and slide the replacement battery into the battery
compartment. For this, use a battery compliant with
the description in the technical data. The battery must
fulfil the safety requirements of UL1642. Otherwise,
there is a risk of combustion or explosion.
5. Dispose of the old battery according to the legal
regulations.
6. Start up the system and the device again and check
the functionality of the UMG 96-RM. Set the date
and time.
c
Dangerous voltage!
Danger to life or risk of serious injury.
Disconnect system and device from power
supply before beginning work.
m
Grease or dirt on the contact surfaces
form a transfer resistance that will
shorten the life of the battery. Only touch
the battery at the edges.
