“Binding” multiple receivers to one model
If necessary, it is possible to bind more than one re-
ceiver to a single model. This is accomplished by initially 
binding the receivers individually, as described in the 
next section. 

that only the receiver which was bound last will 
establish a telemetry link to the transmitter. For this 
reason all telemetry sensors installed in the model must 
be connected to this receiver, since only the last bound 
receiver is able to transmit their data via the down-link 
channel. The second, and all other receivers, run in 
parallel to the receiver last bound to the transmitter, but 
completely independently of it; they operate in Slave 
mode with the down-link channel switched off.

Use the arrow buttons  of the left or right-hand 
touch-key to move to the “rx bind” line:

phase  2

phase  3

phase  4

takeoff

landing

speed

–––

7

6

receiv  out

rx  bind

–––

If you have not already done so, switch on the power 
supply to your receiver now: the red LED on the receiver 
flashes. 
Press and hold the 

 button on the receiver until, 

after about three seconds, the red-flashing LED starts to 
flash red / green; this will last for a further three seconds. 
You can now release the 

 button on the receiver. 

The receiver is in Bind mode as long as the LED flashes 
red / green.

Within this period of about three seconds briefly touch 
the central 

 button of the right-hand touch-key to 

initiate the so-called binding process between a receiver 
and the current model memory. At the same time the 
word “BINDING” starts flashing on the screen in the 
frame of the “Bound receiver” line, instead of the three 
“---”:

phase  2

phase  3

phase  4

takeoff

landing

speed

–––

receiv  out

rx  bind

BINDING

The receiver LED is now flashing red again, and if it 
goes out without 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

phase  4

takeoff

landing

speed

–––

7

6

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 out-
put power in such a way that you can test the system’s 
operation at a distance of less than hundred 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 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. 

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 

 button of the right-

hand touch-key:
