Safety notes
!
These safety instrucons are intended not only to protect the prod-
uct, but also for your own and other people’s safety. Therefore please
read this secon 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 capabilies, or lack of experience or knowledge, or not
capable to use safely the receiver must not use the receiver with-
out supervision or instrucon by a responsible person.
•Operaon 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 reacons of the model to
the remote control commands. Proceed responsibly.
•First, always perform a range and funcon test on the ground (to
do so, hold your model ght), before you use your model. Repeat
the test with running motor and with short throle bursts.
•Only use the components and spare parts that we recommend.
Always use matching, original Graupner plug-in connecons of
the same design and material.
•Make sure that all of the plug-in connecons are ght. When dis-
connecng the plug-in connecons, do not pull the cables.
•Protect the receiver from dust, dirt, moisture and foreign parts.
It must be protected from vibraon 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.
•Always use all your HoTT components only with the latest firm-
ware version.
•If you have quesons which cannot be answered by the operat-
ing manual, please contact us or another expert in the field.

For your safety by handling the transmier and the receiver
!
WARNING
Also while programming the transmier, make sure that a con-
nected motor cannot accidentally start. Disconnect the fuel sup-
ply or drive baery beforehand.
!
CAUTION
Avoid every kind of short-circuit in all sockets of the transmier!
Risk of fire! Use only the suitable connectors. In no case the elec-
tronic component of the transmier or of the receiver may be
changed or modified. Due to licensing reasons, any reconstrucon
and/or modificaon of the product is prohibited.
Note
During transport protect the model and the transmier from dam-
ages.
For your safety by handling the baeries
!
CAUTION
•Protect the baeries from dust, dirt, moisture, heat and vibra-
ons. Only use in dry locaons.
•Do not use any damaged baery.
•Baeries may not be heated, burned, short-circuited.
•If handled improperly, there is a danger of fire, explosion, irri-
taon and burns.
•Leaked electrolyte is causc and should not be touched or
come into contact with your eyes. In case of emergency, rinse
with a large quanty of water and consult a Med. Doctor.
•Stock the baeries in dry and fresh condions.
•Dispose of the baery in the proper disposal centers.

9 / 20
S1012_GR-12L_DE_V1sh
Installaon
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 airght to prevent it from overheang during
operaon.
Servo cables may not be wound around antennas or run next to
them. Make sure that the cables cannot shi to lie directly adjacent
to antennas during flight.
In the case of carbon fibre fuselage, at least the last 35 mm of the
antennas shall be routed from the fuselage.
Connecons
Connect the devices that have to be connected to the receiver to the
row of sockets on one end of the receiver. The servo connecons of
the Graupner-HoTT receiver are numbered.
The polarity of the plug-in system cannot be reversed. Do not apply
force.
Note
For the GR-12L HoTT receiver, insert the connectors with the brown
or black cable upwards.

10 / 20 S1012_GR-12L_DE_V1sh
Power supply
In principle, a baery can be connected to any free socket. By V- or
Y-cable also with any remote control component. If the power sup-
ply is provided by more than one baery, it is important to ensure
that the baeries have the same nominal voltage and rated capacity.
It is not allowed to connect different baery types or rechargeable
baeries 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 con-
nected between baeries and receiver.
Aenon
When selecng and connecng a power supply, be aware that
although the operang range of the receiver ranges from 3.6 to 8.4
V. However, praccally all of the previously marketed servos, speed
controllers, gyros, etc. as well as many which are offered today have
a permissible operang voltage range of 4.8 to 6 V.
Binding
To establish a connecon with the transmier, the Graupner HoTT
receiver must first be "bound" to at least one model memory in "its"
Graupner HoTT transmier. This process is generally called "bind-
ing".
Binding step-by-step
1. Prepare the transmier to be bound according to its instrucons
for binding.
2. Switch on the receiver power supply.
The LED of a GR-12L HoTT receiver lights up red.
3. Press and hold the SET buon on the receiver unl the LED starts
to flash for about 3 seconds aer approx. 3 seconds.
During this me lapse, the receiver is in bind mode.
4. Within this me lapse start the transmier-side binding accord-
ing to the instrucons of the transmier.
5. If the red LED of the GR-12L HoTT receiver goes out, the binding
process has been completed successfully.
Your transmier/receiver combinaon is ready for operaon.

11 / 20
S1012_GR-12L_DE_V1sh
If the red LED of the GR-12L HoTT lights up again constantly, the
"Binding" has failed. Change the posions of the associated
antennas and try the enre procedure again.
Receiver reset
To reset the receiver, press and hold its SET buon while turning on
the power to the receiver:
If the reset was triggered with the transmier switched offor with
an unbound receiver, the red LED of the receiver GR-12L HoTT starts
to flash aer about 3 seconds. The buon will now be released.
If the reset is performed with a not bound receiver, you can then
start a binding process at any me.
If a reset has already been performed on an already-bound receiver
and the associated model memory is acve in the switched-on trans-
mier, then the red LED of the receiver GR-12L HoTT should go out
and thus signal a correct connecon to the transmier. Otherwise
the process has to be repeated.
Notes
•Through a RESET ALL of the sengs in the receiver are brought
to the factory sengs with the excepon of the HoTT synchro-
nizaon informaon!
•If a reset is performed accidentally, all of these sengs that
were made using the "Telemetry" menu in the receiver should
be restored.
•Reseng is parcularly recommendable when you want to
switch a receiver to a different model. This makes it easy to keep
sengs which do not match from being transferred.

12 / 20 S1012_GR-12L_DE_V1sh
Seng and display of the receiver sengs
The receiver-side menus can be viewed and somemes changed
using a suitable HoTT transmier or the SMART-BOX. You can find
out how to open the menus of a receiver in the "Telemetry" secon
of the corresponding manual as well as a detailed descripon of the
receiver menus on the respecve product page at www.graupner.
com on the Internet.
Note
The values shown in the following display illustraons always show
the standard values.
Display "RECEIVER"
ALARM VOLT
•If "SERVO" or "SENSOR" is visible in the "CH5 FUNCTION" line
described below, the operang voltage of the receiver is moni-
tored via the limit value set in the value field of "ALARM VOLT".
•If "BATT-V" is visible in the "CH5 FUNCTION" line described below,
the operang voltage of the drive baery connected via "BATT-V"
is monitored via the limit value set in the value field of "ALARM
VOLT".
In both cases, the actual voltage is shown in the transmier's display
in the "Receiver voltage" field.
If the voltage drops under the set limit value, a transmier-side
alarm takes place in the form of an acousc signal (interval beep long
/ short).
Adjustment range: 2,5 … 22,5 Volt in 0,1 Volt steps.
ALARM TEMP
This opon monitors the receiver temperature. If the set limit is
exceeded, a transmier-side alarm takes place in the form of a con-
nuous beep.
Adjustment range: 30 … 80 °C
PERIOD
In this line, specify the periods for the individual channel pulses. This
seng is transferred for all control channels.
If your system is used exclusively with digital servos, you can set a
cycle me (frame rate) of 10 ms. If your system includes some or
uses exclusively analogue servos, always select 20 ms since the ana-
logue servos may be overloaded and respond by "jiering" or "growl-
ing".

Firmware update
Firmware updates of the receiver are performed via the telemetry
port of the receiver using a PC running Windows 7 ... 10. You will also
need a USB interface, No. 7168.6, and adapter lead, No. 7168.6A or
7168.S, which are available separately.
The programs and files required can be found in the Download area
for the corresponding products at www.graupner.com.
Connect the adapter lead to the USB interface. The polarity of the
plug-in system cannot be reversed. Note the small chamfers on the
sides. Do not use force, the plug should click into place easily.
Connect the other end of the adapter lead to the socket of the
receiver GR-12L HoTT labelled with "-+5T". The polarity of the plug-in
system cannot be reversed. Do not apply force. The plug should be
fully inserted.
In addion, this connecon has to be set to "SERVO" for the duraon
of the update process.
The update is carried out via the "HoTT device" program secon of
the program "Firmware_Upgrade_gr_Studio". Please follow the
notes of the soware. The further procedure is also described in
detail in the manual contained in the data package. You can also
download these from the download page of the product at
