Use an appropriate screwdriver to undo the two screws on the
battery compartment cover (on the opposite side from the quartz
mechanism). Remove the battery compartment cover and insert a bat-
tery of the correct type (LR14) (refer to the table under section 6 –
technical data ) into the battery compartment. Please refer to the dia-
gram on the housing to make sure that battery is inserted with the cor-
rect 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 mechanism in order to set the correct time.
