Symbols explication
!
Always observe the information indicated by this warning sign.
Particularly those which are additionally marked with the CAU-
TION or WARNING. The signal word WARNING indicates the poten-
tial for serious injury, the signal word CAUTION indicates possibil-
ity of lighter injuries.
The signal word Note indicates potential malfunctions.
Attention indicates potential damages to objects.
Safety notes
!
These safety instructions are intended not only to protect the
product, but also for your own and other people’s safety. There-
fore please read this section very carefully before using the prod-
uct!
Do not carelessly leave the packaging material lying around,
since it might become a dangerous toy for children.
Persons, including children, with reduced physical, sensory
or mental capabilities, or lack of experience or knowledge,
or not capable to use safely the receiver must not use the
receiver without supervision or instruction by a responsible
person.
Operation and use of radio-controlled models needs to be
learned! If you have never operated a model of this type
before, start carefully and make yourself familiar with the
model's reactions to the remote control commands. Pro-
ceed responsibly.
First, always perform a range and function test on the ground
(to do so, hold your model tight), before you use your model.
Repeat the test with running motor and with short throttle
bursts.
Before you start using the remote control model, you have
to check the further relevant laws and regulations. These
laws you must obey in every case. Pay attention to the pos-
sibly different laws of the countries.

The insurance is mandatory for all kinds of model operation.
If you already have one, please inform yourself if the opera-
tion of the respective model is covered by your insurance. If
this is not the case, conclude a special liability insurance pol-
icy for models. We recommend to provide your model with
a label, where your personal data are indicated. So that the
model can be clearly assigned in the event of a crash.
Due to safety and licensing reasons (CE), any reconstruction
and/or modification of the product is prohibited.
Only use the components and spare parts that we recom-
mend. Always use matching, original Graupner plug-in con-
nections of the same design and material.
Make sure that all of the plug-in connections are tight. When
disconnecting the plug-in connections, do not pull the
cables.
Protect the receiver from dust, dirt, moisture and foreign
parts. It must be protected from vibration as well as exces-
sive heat or cold. The models may only be operated remotely
in normal outside temperatures such as from -10°C to
+55°C.
Only operate all your components using the current software
version.
If you have questions which cannot be answered by the
operating manual, please contact us or another expert in the
field.
WARNING
Also while programming, make sure that a connected elec-
tric motor cannot accidentally start. Risk of injury by rotating
propellers!
Avoid shock and pressure. Check the receiver regularly for
damages to the housings and cables, specially after model
crashes. Damaged or wet receiver, even if re-dried, should
no longer be used!

Installation
The receiver must be aligned at right angles to the model on the
receiver platform.
The lower surface of the receiver must always be parallel to one
of the model sides.
Prior to installation, remove the sticker on the back of the receiver.
We recommend using double-sided tape No.: S8376 for Gr-18
to fix the receiver in place.
Binding
Binding is only possible if the receiver has not been linked with
a bound transmitter since being switched on (red LED lights).
Press the SET button to set the receiver to BIND mode.
If you wish to bind the receiver to a new model memory, this is
the procedure:
Switch the transmitter’s RF section off in the “Basic model
settings” menu (see transmitter manual)
Switch on the receiver and put it in binding mode, by press-
ing and holding the binding button (green and red LED on
the receiver are flashing)
Initiate binding in the transmitter’s “Basic model settings”
menu.
If the red LED of the receiver goes out within about 10 sec-
onds, the binding process has been completed successfully.
Your transmitter/receiver combination is now ready for oper-
ation.
If the red LED is still lit, the "binding“ failed. In this case,
repeat the whole procedure.

Connections
Connect the servos to the row of sockets on one end of the
receiver. The connectors are reverse polarity protected: note the
small chamfers on the sides. Never use force – the connectors
should engage easily. The polarity is also printed on the receiver;
the negative wire (-) is brown, the positive (+) red and the signal
orange. The servo sockets of Graupner/SJ HoTT 2.4 receivers
are numbered sequentially.
The socket for channel 6 can also be programmed to deliver a
(digital) sum signal (see receiver settings section).
Power supply
The receiver does not feature specific sockets for connecting
the battery. We recommend that you connect the power supply
to the socket(s) close to the servos already connected to the
receiver. If you wish to connect multiple separate batteries, the
batteries must be of the same nominal voltage and capacity.
Never connect different battery types or batteries with strongly
different charges since this can cause an effect similar to a short
circuit. In such cases for safety reasons, insert voltage stabiliz-
ing elements such as PRX-5A (No. 4136) receiver power sup-
plies between the batteries and receiver.
Attention!
Never connect a battery with voltage higher than 8,4V directly to the
receiver! The receiver and the connected servos would be destroyed.
Telemetry or channel (T/5) socket
The socket is also used for channel 5
The optional telemetry sensors or modules are connected to the
socket marked “T” (T/5)- Telemetry. In addition, the update is
performed on this socket (see firmware update section).

Programming the receiver settings
The receiver can be programmed with a suitable HoTT transmit-
ter or in connection with the SMART-BOX.
Receiver settings menu
The receiver setup menu appears in the “Telemetry“ menu under
SETTINGS / DISPLAYS or if you are using a SMART-BOX under
SETTING & DATAVIEW. How to access this menu is described
in the operating instructions supplied with your transmitter or
Smart-Box.
Low voltage warning (ALARM VOLT):
If the receiver voltage or the external voltage at channel 5 falls
below the set value, a low-voltage warning is generated by the
transmitter's RF module in the form of a "general alarm tone"
(regular beeping at a rate of approx. one beep per second) or
the "receiver voltage" speech output message.
Temperature warning (ALARM TEMP):
If the receiver temperature exceeds the set temperature, a warn-
ing is generated by the transmitter’s RF module in the form of a
"general alarm tone" (regular beeping at a rate of approx. one
beep per second) or the "receiver temperature" speech output
message.
Maximum altitude (Altitude max.) - only by No. 33577 with inte-
grated Vario:
this is where you can specify a maximum altitude. When the
model reaches this altitude, an alarm is triggered either by the
transmitter's RF module in the form of a "general alarm tone"
(regular beeping at a rate of approx. one beep per second) or
the "altitude" speech output message. Note: When the receiver
is switched on, the model's current altitude is set to 0; the dis-
played altitude is therefore the altitude relative to the launch
point.
Cycle time (CYCLE):
Cycle time (PERIOD): If your system is used exclusively with dig-
ital servos, you can set a cycle time (frame rate) of 10 ms. If your
system includes some or uses exclusively analogue servos, you
should always select 20 ms, as many analogue servos cannot
process the higher frame rate and may respond by "jittering" or
"growling".
HoTT sum signal (SUMD):
If you activate the digital sum signal at channel 6, a sum signal
containing 8 channels is present at this socket, instead of a
servo signal.
