8.1 Batteries
MEDUMAT Standard a is fitted with two batteries
which should always be replaced simultaneously.
Caution!
Batteries and rechargeable
batteries do not belong in
domestic waste! Every
consumer is obliged by law
to hand in all batteries and
rechargeable batteries, re-
gardless of whether they
contain harmful substances
or not, at a community/lo-
cal collection point or at a
store so that they can be
disposed of in an environ-
mentally-friendly way.
A CR2430 button cell supplies auxiliary power to the
electronics if the main batteries fail. This makes it
possible to set off an alarm if the main batteries fail.
At the same time, the MEDUMAT Standard a
switches to expiration.
The battery capacity is calculated to be sufficient for
power requirements under normal operating condi-
tions for the full period between servicing every two
years. All the batteries are replaced at every two
years during servicing.
We recommend having the batteries changed only
by Weinmann the manufacturer or by qualified per-
sons expressly authorized by that company. Special
precautions need to be taken during the change in
order to prevent disruption of the electronics.
The following action should be taken in emergen-
cies:
18: Button cell for auxiliary power
19: Fuse protecting against internal
short circuit
20: 3.6 V lithium battery for main
power supply to
