Operating notices
Opening the transmitter housing to change the mode
Carefully read the notices below before opening the
transmitter housing. We recommend that unexperienced
users request a Graupner Service location to take care of
the procedures described below.
Attention:
Switch off the transmitter before opening the
housing (press power key at least 2 seconds).
Open the battery compartment and remove the
battery holder as described above.
Then loosen the six countersunk screws on the rear of
the transmitter with a PH1 Phillips screwdriver (refer to
figure above).
Hold the two housing sections together by hand then turn
the transmitter upright over a suitable surface to allow the
six screws to drop out. Now carefully lift the backplate and
fold it open to the right as you would open a book.
WARNING:
• Make no modifications of any kind to the
circuitry as this will void the guarantee as well as
the type approval.
• Be sure not to touch the circuit boards with
any metallic objects. Do not touch contacts with
your fingers.
• Never switch the transmitter on when its
housing is open.
