Safety notes
!
These safety instructions are intended not only to protect the prod-
uct, but also for your own and other people’s safety. Therefore please
read this section very carefully before using the product!
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 men-
tal capabilities, or lack of experience or knowledge, or not capable
to use safely the receiver must not use the receiver without super-
vision 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 reac-
tions to the remote control commands. Proceed 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 possibly 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 operation of
the respective model is covered by your insurance. If this is not
the case, conclude a special liability insurance policy 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 recommend.
Always use matching, original Graupner plug-in connections of
the same design and material.
Make sure that all of the plug-in connections are tight. When dis-
connecting 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 excessive heat or
cold. The models may only be operated remotely in normal out-
side 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 operat-
ing manual, please contact us or another expert in the field.
WARNING
Also while programming, make sure that a connected electric
motor cannot accidentally start. Risk of injury by rotating propel-
lers!
Avoid shock and pressure. Check the receiver regularly for dam-
ages to the housings and cables, specially after model crashes.
Damaged or wet receiver, even if re-dried, should no longer be
used!

Installation
Install the receiver so that the connecting cables for the servos and
power supply remain loose, and so that the receiving antennas are
at least 5 cm from all large metal parts or wires. This includes carbon
fiber parts, servos, electric motors, fuel pumps, all types of cables,
etc. in addition to steel parts. It is preferable to install the receiver
away from all other installed parts at an easily accessible location in
the model. Servo cables may not be wound around antennas or run
next to them.
If the fuselages are made of carbon fiber, the ends of the antennas
should extend from the fuselage by at least 35 mm. If necessary,
exchange the approx. 145 mm standard antennas for HoTT receivers
with the 300 mm or 450 mm long antennas No. 33500.2 or 33500.3.
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 set-
tings” menu (see transmitter manual)
Switch on the receiver and put it in binding mode, by pressing
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 seconds
and the green LED is illuminated, the binding process has been
completed successfully.
Your transmitter/receiver combination is now ready for opera-
tion.
If the red LED is still lit, the "binding“ failed. In this case, repeat
the whole procedure.

Connection S1012 - GR-12L
Connect the servos to the row of sockets on one end of the receiver.
The connectors are reverse polarity protected: note the small cham-
fers 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-HoTT 2.4 receivers are numbered sequentially.
Attention
A servo plug must never be inserted horizontally on the vertical servo
connectors. Orientation of the servo connectors as indicated on the
receiver. Risk of short-circuit.
The socket for channel 6 can also be programmed to deliver a (digi-
tal) 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 stabilizing elements such as PRX-5A (No.
4136) receiver power supplies 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 per-
formed on this socket. (see section Firmware update)

10 / 16 S1037_S1012_jh_V1
Connection S1037 - GR-12L SUMD+T
Connect your Flybarless system to the SUMD connector.
You can connect HoTT sensors to the Telemetry port.
The colors of both cables mean:
brown cable (-) power supply
red cable (+) power supply
orange cable (signal) telemetry or SUMD
Power supply
You can connect the power supply to the receiver through one of the
two cables. Always use only one cable and one power supply. Make
sure that the power supply voltage is not higher than 8,4V DC.
