• Remove the installation button that may be located in front of the flush-mounted battery
transmitter.
If voltage-carrying cables/terminal strips/junction box terminals are
present in the installation box, then first switch off the respective electri-
cal circuit by turning and removing the relevant fuse or switching off the
circuit breaker.
Make sure that nobody accidentally switches on the electrical circuit (safety
warning on the in-house distributor, mechanical block, etc.).
Then use a suitable measuring device to check whether the affected electric
circuit is fully voltage-free.
Only then should you continue.
• Carefully remove the ‘FS20 S4UB’ flush-mounted battery transmitter from the installation
box.
• Carefully cut open the transparent shrink film.
Never short circuit contacts on the battery or circuit board. Do not
damage any components or the circuit board itself.
CAUTION!
A short-circuit of the lithium battery (even if it is almost empty) can cause
an explosion!
• Remove the battery from its holder.
Make sure you use a non-conductive tool to do this!
A short-circuit of the battery can cause an explosion!
• To dispose of the battery, wrap it up separately using non-conductive packaging such as
an untreated plastic bag.
Never throw the battery into a container with other batteries (these could cause a short-
circuit).
Afterwards, take the individually wrapped battery to a disposal station (see section 13).
• Now insert a new battery of the same type (BR 3032) into the battery holder, observing the
correct polarity. Use a non-conductive tool here as well.
