recommend that you ask a friend to help with range-
checking.

Install the receiver in the model as required, preferab-

1. 

ly after completing the binding process with the trans-
mitter.
Switch the radio control system on and wait until the 

2. 

green LED on the receiver glows. Now you can obser-
ve the servo movements.
Place the model on a fl at surface (paving, close-mown 

3. 

grass or earth), with the receiver aerials at least 
15 cm above the ground. This means that you may 
have to place the model on a raised object for the pe-
riod of the check.
Hold the transmitter at hip-height, and away from your 

4. 

body. However, do not point the aerial straight at the 
model; instead rotate and / or angle the tip of the aeri-
al so that it is vertical while you carry out the check.
Make sure that the transmitter in the „normal“ mode 

5. 

- mode switch to the rear. Now press the BIND-but-
ton for about 5 s, until the transmitter starts to beep 
permanently. Disengage the BIND-button again. Note 
when using multiple receivers for each model: the 
range test only works with the receiver which trans-
mits the telemetry signal - that is the last bound re-
ceiver.
When you start the range-check, the transmitter’s 

6. 

output power is signifi cantly reduced, at the same 
time a permament beep sounds. When the 99 se-
conds of the range-check period have elapsed, the 
transmitter switches back to full power, and the beep 
sound stops. Note: you can stop the range test at 
any time by pressing again the BIND button.
Within this period walk away from the model, moving 

7. 

the sticks all the while. If at any point within a distance 

of about fi fty metres you notice a break in the connec-
tion, attempt to reproduce it.
If the model is fi tted with a motor, switch it on in order 

8. 

to check the system’s interference rejection.
Walk further away from the model until you no longer 

9. 

have full control over it.
At this point wait until the test period has elapsed, with 

10. 

the model still switched on and ready for use. When 
the range-check period is over, the model should re-
spond again to control commands. It this is not 100% 
the case, do not use the system. Contact your nearest 
Service Centre of Graupner GmbH & Co. KG.
Carry out the range-check before every fl ight, and si-

11. 

mulate all the servo movements which are likely to oc-
cur in a typical fl ight. To ensure safe operation of the 
model, the range must always be at least fi fty metres 
on the ground.
