Changing the battery
The Multiroom module contains a
lithium battery (see graphic: MP5),
which ensures that the time isn’t lost
during a power-failure or while the
unit is being transported. The lithium
battery is not used in standby or
normal operation. The battery only
provides power for the Timer IC when
the M51 is separated from the power
or when it is switched off at the power
switch. All batteries discharge
somewhat on their own, without any
load being connected to the battery.
If after some years of operation, you
notice that the correct time is not
displayed after a power outage, this
indicates that is time to change the
lithium battery.
You need a CR2032 3 V lithium battery
as the replacement.
You can purchase one of these
batteries direct from Revox, with the
part number 98.01.2203 or from a
specialist electrical shop.
The Multiroom module is removed
from the M51 to change the battery.
The steps you have to carry out and
the precautions you have to take are
explained in the previous Chapter
Installation , on Page 3.
