sing to make sure that battery is inserted with the correct polarity. Refit
the battery compartment cover (the spring faces towards the battery),
refit the battery compartment cover screws and tighten securely. Then
use the white adjusting wheel on the housing of the clockwork mecha-
nism in order to set the correct time.
7.2 Changing the battery
To change the battery, use an appropriate screwdriver to undo the two
screws on the battery compartment cover. Remove the battery com-
partment cover and dispose of the old battery.
Insert a new battery (only use type-approved batteries ' refer to the
table under section 6 – technical data; check for correct polarity '
check the diagram on the battery housing ). Refit the cover to the bat-
tery compartment (the spring faces towards the battery) and secure it
with the two screws. The clock will now start to run again. Then use
the white adjusting wheel on the housing of the quartz mechanism in
order to set the correct time.
Please ensure that all used and defective batteries are properly dispo-
sed of in an environmentally friendly manner.
7.3 Wall Mounting
An integral metal bracket located on the rear of the clock enables the
Ex-Time 40 / 50 to be suitably mounted on an appropriate wall. The
fixing of the unit must be secure at all times and precautionary measu-
res must be taken to prevent the Ex-Time 40 / 50 from
falling into an area classified as zone 0.
7.4 Time Setting
The white adjusting wheel on the quartz mechanism is used to make
any necessary time adjustments.
