17 Operating Notes
Adjusting stick length
Both sticks are infinitely variable in length over a broad
range, enabling you to set them to suit your personal
preference.
Hold the bottom half of the knurled grip firmly, and
unscrew the top section:
Now screw the stick top in or out (shorter or longer) to
the length you prefer before tightening the top and bot-
tom sections against each other to fix the stick top.
Opening the transmitter case
Please read the following notes carefully before you
open the transmitter. If you have no experience in such
matters, we recommend that you ask your nearest
Graupner Service Centre to carry out the work for you.
The transmitter should only be opened in the following
cases:
When a self-neutralising stick needs to be converted •
to non-neutralising action, or a non-neutralising stick
to a self-neutralising action.
If you wish to adjust the stick centring spring tension.
•
Before opening the transmitter check that it is switched
off (move Power switch to “
OFF
”).
Open the battery compartment and remove the transmit-
ter battery as described on the previous double page,
together with any micro-SD card already installed.
After this, use a PH1-size cross-point screwdriver to
undo the six screws recessed into the back panel of the
transmitter, as shown in the illustration:
Arrangement of the case back screws
Hold the two case sections together with your hand, and
turn the unit over to allow these six screws to fall out
onto the table. Now carefully raise the case back and
fold it open to the right, as if you were opening a book.
C A U T I O N
Two multi-core cables connect the lower shell to the
transmitter electronics located in the top section.
Please take great care not to damage this cable!
Important:
Do not modify the transmitter circuit in any way, •
as this invalidates your guarantee and official ap-
proval for the system.
Do not touch any part of the circuit boards with
•
any metal object. Avoid touching the contacts
with your fingers.
Never switch the transmitter on while the case is
•
open.
Please note the following points when closing the
transmitter:
Make sure that no cables are jammed between the •
transmitter case sections when you close the back.
Check that the two case sections fit together flush all
•
round before fitting the retaining screws. Never force
the two case components together.
Fit the case screws in the existing threads, and tight-
•
en them gently. Over-tightening them will strip the
threads in the plastic.
Remember to re-connect the battery.
