Inserting/replacing the Ex battery pack

pack.

Opening the battery compartment
Risk of explosion:
Local and operational factors may lead to an
explosive atmosphere in an Ex zone. Therefore
never open the handset battery compartment in
an Ex zone, rather only outside an Ex zone and
only in a dust-free environment.
1. Loosen and remove the screw from the battery cover
with the Allen key.
2. Insert a suitable screwdriver into the recess between
the housing and battery cover, turn it and then raise
the battery cover.
