Batteries And Fuses; Adjusting The Pressure Gauge - Weinmann MEDUMAT Basic Servicing And Repair Instructions

4.2 Batteries and fuses

MEDUMAT Basic / Basic p is fitted with two bat-
teries which must always be changed together:
A button cell CR2430
17
with auxiliary power if the capacity of the main
battery is exhausted. This means that an alarm
19
can still be activated in the event of sudden failure
of the main battery. The device switches to expira-
tion.
As a general rule, the capacities of the batteries
are designed in such a way that under normal us-
age conditions, they do not need to be changed
during the 2-year servicing intervals. Within the
context of the prescribed 2-year servicing, the bat-
teries are replaced completely.
We recommend that the batteries be changed
only by the manufacturer Weinmann or by authori-
sed specialists explicity authorised by them, since
special precautions must be taken to protect the
electronics (see "6.6 Changing the batteries" on
page 23)).
For information on replacing the fuse, see Section
„6.7 Replacing the fuse" on page 24.

1. Carefully lever out the plastic cover of the ad-
justing screw.
