7. Use and Application / Operating Instructions

Before use, please read these operating instructions very carefully in
order to familiarise yourself with the functions of the Ex-Time
40 / 50. For you own safety and information, please read the
following instructions.

7.1 Commissioning

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 bat­tery of the correct type (LR14) (refer to the table under section 6 –
technical data ) into the battery compartment. Please refer to the dia­gram on the housing 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 mechanism 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 com­partment 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 bat­tery 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 dispo­sed of in an environmentally friendly manner.
