touch-key within this period of about three seconds:
this initiate the binding process between a receiver and
the current model memory. At the same time the word
“BINDING” starts flashing in the frame of the “rx bind”
line on the screen, instead of the three “---”:
phase 2
phase 3
hover
speed
5
4
autorotat. 2
receiv out
rx bind BINDING
The receiver LED is now flashing red again, and if it
goes out within about ten seconds, and instead glows
a constant green, then the binding process has been
completed successfully. Your model / receiver combina-
tion is now ready for use. In parallel with this the screen
displays the code number for the receiver now “bound”
to this model memory. For example:
phase 2
phase 3
hover
speed
5
4
autorotat. 2
receiv out
rx bind R08
If, in contrast, the red LED on the receiver flashes
for longer than about ten seconds, then the binding
process has failed. In parallel with this the screen will
display three “---” once more. If this should occur, alter
the relative position of the aerials and repeat the whole
procedure.
Range test
The integral range-check reduces the transmitter’s output
power in such a way that you can test the system’s
operation at a distance of up to about fifty metres.
Carry out the range-check of the
Graupner|SJ 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 flat 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 period of
the check.
Hold the transmitter at hip-height, and away from your
4.
body. Do not point the aerial straight at the model; in-
stead rotate and / or angle the aerial tip so that it is
vertical while you carry out the check.
If you have not already done so, use the arrow but-
5.
tons  of the left or right-hand touch-key to move
to the “Test range” line, and initiate range-check
mode by briefly pressing the central
SET
button of
the right-hand touch-key:
phase 3 speed 4
autorotat. 2

rx bind R08
range test 99sec
When you start the range-check, the transmitter’s
output power is significantly reduced, and the blue
LED on the aerial base starts to flash. At this point
the time display on the transmitter screen starts
counting down, and a double beep sounds every five
seconds.
From five 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 fifty metres you notice a break in the connec-
tion, attempt to reproduce it.
If the model is fitted 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,
9.
with the model still switched on and ready for use.
When the range-check period is over, the model
should respond again to control commands. It this is
not 100% the case, do not use the system. Contact
your nearest
Graupner Service Centre.
Carry out a range-check before every flight, and sim- 10.
ulate all the servo movements which are likely to oc-
