Safety notes
These safety instructions are intended not only to protect the product, but also for your own and other people’s safety. Therefore please
read this section very carefully before using the product!
• Do not leave the packaging material lying around, this could be 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 learnt!
If you have never driven such a model, then start extra carefully
and make sure to be familiar with the reactions of the model 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.
• 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 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 excessive heat or
cold. The models may only be operated remotely in normal outside temperatures such as from -10°C to +55°C.
• Always use all your HoTT components only with the latest firmware version.

• 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.
In Germany for example, 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. In addition, models with a take-off weight
of 250 g or higher are to be provided with a fireproof sticker bearing the name and address of the owner. And for a model operation outside of designated model airfields usually a proof of
knowledge is always required.
• Due to safety and licensing reasons (CE), any reconstruction and/
or modification of the product is prohibited.
• If you have questions which cannot be answered by the operating manual, please contact us or another expert in the field.
For your safety by handling the transmitter and the receiver
For your safety by handling the batteries
CAUTION
• Protect the batteries from dust, dirt, moisture, heat and vibrations. Only use in dry locations.
• Do not use any damaged battery.
• Batteries may not be heated, burned, short-circuited.
• If handled improperly, there is a danger of fire, explosion, irritation and burns.
• Leaked electrolyte is caustic and should not be touched or
come into contact with your eyes. In case of emergency, rinse
with a large quantity of water and consult a Med. Doctor.
• Stock the batteries in dry and fresh conditions.
• Dispose of the battery in the proper disposal centers.
WARNING
Also while programming the transmitter, make sure that a connected motor cannot accidentally start. Disconnect the fuel supply or drive battery beforehand.
Avoid impacts and crushing. 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!
CAUTION
Avoid every kind of short-circuit in all sockets of the transmitter!
Risk of fire! Use only the suitable connectors. In no case the electronic component of the transmitter or of the receiver may be
changed or modified. Due to licensing reasons, any reconstruction
and/or modification of the product is prohibited.

Installation
Power supply
Connections
The receiver must be protected against dust, exhaust gases, splash
water, etc. in the model. When you install your receiver, make sure
that it is not excessively airtight to prevent it from overheating during
operation.
Servo cables may not be wound around antenna or run next to it.
Make sure that the cables cannot shift to lie directly adjacent to
antennas during flight.
For carbon fiber fuselages, the antenna should be routed out of the
fuselage as far as possible.
Attention
The cables to be connected to the receiver must be plugged into the
connector strip of the receiver in accordance with the printed polarity information. Do not apply force. Although the plug-in system is
reverse polarity protected, the two receivers differ not only in the
type of plug-in system, but also in the order of the cables:
In principle, a battery can be connected to any free socket. By V- or
Y-cable also with any remote control component. If the power supply is provided by more than one battery, it is important to ensure
that the batteries have the same nominal voltage and rated capacity.
It is not allowed to connect different battery types or rechargeable
batteries with too different charge states to the receiver, as short-
circuit-like effects can occur. For safety reasons, voltage stabilizers
such as PRX-5A receiver power supplies No. 4136 should be connected between batteries and receiver.
Attention
When selecting and connecting a power supply, be aware that
although the operating range of the receiver ranges from 3.6 to 8.4
V. However, practically all of the previously marketed servos, speed
controllers, gyros, etc. as well as many which are offered today have
a permissible operating voltage range of 4.8 to 6 V.
GR-12SH+ HoTT GR-12SC+ HoTT
The red wire must end on the connector marked with "+", brown or
black on the one with "-" and orange on the one marked with a
number.
Note
RC components with the usual JR servo connectors can be connected with the aid of the adapter cable No. 33565.1 on receiver
GR-12SH+ and adapter cable No. 23048 for the receiver GR-12SC+
HoTT.

Binding
Setting and display of the receiver settings
To establish a connection with the transmitter, the Graupner HoTT
receiver must first be "bound" to at least one model memory in "its"
Graupner HoTT transmitter. This process is generally called "binding". However, the methods to be used are not always the same, so
the following step-by-step instructions apply only to binding a
GR-12SH+ or GR-12SC+ HoTT receiver to any transmitter:
Attention
As soon as the receiver is switched on and as long as its LED is constantly red, the receiver is in bind mode. And just as long there is
also the risk that the receiver inadvertently binds to another, coincidentally at the same time in the same place also in binding mode,
HoTT transmitter whereupon the model can start uncontrolled at
any time.
• If the receiver is already bound to a specific transmitter and this
binding should be maintained, the transmitter should ideally be
switched on before the receiver.
• If the receiver is unbound or it should be bound to another transmitter or only the model memory has to be changed than the
previous one, proceed as follows:
Binding step-by-step
1. Prepare the transmitter or model memory to be bound according
to the instructions for binding.
2. Switch on the receiver power supply.
The LED of a GR-12SH+ or GR-12SC+ HoTT receiver lights up con-
stantly red.
3. Start the transmitter-side binding according to the instructions of
the transmitter.
4. If the red LED of the GR-12SH+ or GR-12SC+ HoTT receiver goes
out, the binding process has been completed successfully.
Your transmitter/receiver combination is ready for operation.
If the red LED of the GR-12SH+ or GR-12SC+ HoTT starts to light
up again, the "Binding" has failed. Change the positions of the
associated antennas and try the entire procedure again.

Note
The values shown in the following display illustrations always show
the standard values.
ALARM VOLT
• If "SERVO" or "SENSOR" is visible in the "C5" line described below,
the operating voltage of the receiver is monitored via the limit
value set in the value field of "ALARM VOLT".
• If "VOLTAGE" is visible in the "C5" line described below, the operating voltage of the drive battery connected via "VOLTAGE" is
monitored via the limit value set in the value field of "ALARM
VOLT".
In both cases, the actual voltage is shown in the transmitter's display
in the "Receiver voltage" field.
If the voltage drops under the set limit value, a transmitter-side
alarm takes place in the form of an acoustic signal (interval beep long
/ short).
Adjustment range: 2,5 … 24,0 Volt in 0,1 Volt steps.
ALARM TEMP
This option monitors the receiver temperature. If the set limit is
exceeded, a transmitter-side alarm takes place in the form of a continuous beep.
Adjustment range: 50 … 80 °C in 5 degree steps.
PERIOD
In this line, specify the periods for the individual channel pulses. This
setting is equally valid for all control channels.
If your system is used exclusively with digital servos, you can set a
cycle time (frame rate) of 10 ms. If your system includes some or
uses exclusively analogue servos, always select 20 ms since the analogue servos may be overloaded and respond by "jittering" or "growling".
