range test
The integral range-check reduces the transmitter’s out-
put power in such a way that you can test the system’s
operation at a distance of up to about fi fty metres.
Carry out the range-check of the Graupner HoTT
system in accordance with the following instructions. We
recommend that you ask a friend to help with range-
checking.
Install the receiver in the model as required, prefer-1.
ably after completing the binding process with the
transmitter.
Switch the radio control system on and wait until the 2.
green LED on the receiver glows. Now you can ob-
serve 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.
If you have not already done so, use the arrow but-5.

When you start the range-check, the transmitter’s
output power is signifi cantly reduced, and the blue
LED on the aerial base starts to fl ash. At the same
time the time display on the transmitter screen starts
counting down, and a double beep sounds every fi ve
seconds.
From fi ve seconds before the end of the range-check
you will hear a triple beep every second. When the
99 seconds of the range-check period have elapsed,
the transmitter switches back to full power, and the
blue LED glows constantly once more.
Within this period walk away from the model, moving 6.
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 7.
to check the system’s interference rejection.
Walk further away from the model until you no longer 8.
have full control over it.
At this point wait until the test period has elapsed, with 9.
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 10.
simulate all the servo movements which are likely to
occur in a typical fl ight. To ensure safe operation of
the model, the range must always be at least fi fty me-
tres on the ground.
Caution:
Never initiate a range-check when you are actually
operating a model!
RF transmit
In this menu line you can manually switch the transmit-
ter’s RF transmission on and off again for a specifi c
model for the current period that the transmitter is
switched on. For example, you might wish to do this to
save power when demonstrating the programming of a
model. If you switch the transmitter off with the RF
module switched off, next time you switch the trans-
mitter on it will be switched back on again.
Use the arrow buttons cd of the left or right-hand four-
way button to move to the “RF module” line, and press
the central SET button of the right-hand four-way button
to activate the v
