Operating notices
 Joystick length adjustment 
The length of both joysticks can be continuously 
adjusted to adapt these transmitter controls to the pilot's 
preference.
Hold the lower half of the knurled grip in place then turn 
the upper section to release its counter-locked threads. 
 
Now pull up or push down on the joystick's end to the 
desired length. When the length is suitable, tighten the 
counter-locked threads of the upper and lower sections 
again.
  Opening the transmitter housing
Carefully read the notices below before opening the 
transmitter housing. It may be better if unexperienced 
users ask a Graupner Service location to take care of 
the procedures described below.
The transmitter should only be opened in the following 
situations:
to convert a neutralized joystick to a non-neutralized 
• 
joystick or a non-neutralized joystick to a neutralized 
joystick.
to adjust joystick return tension.
• 
Switch off the transmitter before opening its cover 
(power switch to "OFF"). 
Open the battery compartment as described on the 
previous double-page, remove the battery and if a micro 
SD card is inserted be sure to remove it too.
Once the battery and any micro SD card have been 
removed, loosen the six countersunk screws on the rear 
of the transmitter with a Phillips, size PH1, screwdriver, 
see illustration.
Housing screw locations
 
Hold the two housing sections together by hand then 
turn the transmitter upright over a suitable surface so 
these 6 screws can fall out without getting lost. Now lift 
up on the backplate carefully and turn it open to the right 
like you would open a book.
A T T E N T I O N:
Two multi-conductor cables connect the backplate 
with the transmitter electronics in the upper section. 
These connections must not be damaged.
Important notices:
Make no modifi cations of any kind to the circuitry 
• 
as this will void the guarantee as well as the 
unit's offi cial permit.

• 
metallic objects. Do not touch contacts with your 
fi ngers.

that …

another before screwing them together. Never force 
the housing sections together.
Turn the screws down into the existing housing

threads without stripping them out.
