Note:
The maximum number of lines (outputs) available
reflects the maximum number of servos which can be
connected to the receiver in question.
RF transmit
This menu line provides an option for manually
switching the transmitter’s RF transmission on and off
to specific models while the transmitter is in opera-
tion. For example, to save power while a model is be-
ing programmed. If this line option was set to OFF,
it will be canceled (i. e. set to ON) the next time
the transmitter is switched on.
If necessary, use the  selection keys of the left or
right four-way button to move into the “RF transmit“
line then activate the option with a brief tap on the
center SET button of the right four-way button:

The right selection keys can now be used to choose

SET key of the right four-way button will conclude the
entry.
Range test
Note:
This menu line is suppressed if you select “EXT.” or
“SP.” in the “Module” line.
The built-in range test reduces transmission power
to an extent that a functional test can be carried out
even within a distance of less than 100 m.
Perform a range test on the Graupner/SJ HoTT sys-
tem according to the following instructions. If neces-
sary, have someone assist you in carrying out the
range test.
1. Preferably, the receiver already bound to the trans-
mitter should be installed into the model in its in-
tended position.
2. Switch remote control on and wait for the green
LED to light up on the receiver/s. Now servo move-
ments can be observed.
3. Place the model on a level surface (pavement,
low-cut grass or bare ground) such that receiv-
er antennas are at least 15 cm above ground lev-
el. It may be necessary to put something under the
model to raise it up enough for this.
4. Hold the transmitter at hip level and at some dis-
tance from one’s body.
5. If necessary, use the  selection keys of the
left or right four-way button to reach the “RF range
test” line in the menu then start range test mode
with a tap on the center SET key of the right four-
way button:

RF Range Test 99sec
When the range test has been initiated, the trans-
mitter’s transmission power will be significantly re-
duced and the green LED just to the right of the
main switch on the transmitter, marked RF, will
begin to blink; this will also be accompanied by
acoustic tones. At the same time, the timer in the
transmitter’s display will start counting down and
every 5 seconds a two-frequency tone will sound.

TEST 76s
Five seconds prior to the end of the range test a
three-frequency tone will sound once every sec-
ond. After expiration of the range test’s 99th sec-
ond the transmitter will again be switched to full
output power and the green LED just to the right of
the main switch on the transmitter will again illumi-
nate constantly.
6. Move away from the model while manipulating
the sticks during this timespan. If you notice an in-
terruption anytime while still within a distance of
about 50 m, try to reproduce this malfunction.
7. If there is a motor in the model, it may be neces-
sary to switch it on to further check noise immuni-
ty.
8. Continue moving away from the model until perfect
control is no longer possible.
9. Wait at this distance for the remainder of the test
period with the still-operationally-ready model
to expire. After the range test is ended it should
again respond correctly to all RC controls. If this is
not 100 % the case, do not use the system. Con-
tact your area’s Graupner GmbH & Co. KG service
partner.
10. Perform the range test before each flight and, in
doing so, simulate all servo movements which also
take place during flight. The range must always be
at 50 m on the ground in order to assure safe mod-
el operation.
Caution:
Never start the range test on the transmitter dur-
ing normal operation of the model.
