see section "Installation of the receiver system" on pages 8 - 11.
When using digital servos, we recommend using a rechargeable battery with 5 cells (6 V) of sufcient
capacity or a BEC system* of adequate power. When using both, analog and digital servos, it is imperative
to observe the respective maximum permitted operating voltage. For safety reasons, do never use battery
boxes or dry cell batteries.
Check the condition of the rechargeable batteries at regular intervals. Do not wait until the servos become
noticeably slower, before charging the batteries.

Protect all equipment from dust, dirt, moisture. Only use in dry locations.
Do not use any damaged battery. Risk of injury!
Any alterations to the battery can cause serious injury. Risk of re!
Batteries may not be heated, burned, short-circuited or charged with excessive current or with reversed polarity.
While they are being charged, the batteries must be placed on a non-ammable, heat-resistant and non-conductive surface.
Combustible or highly ammable objects are to be kept away from the charging area. Batteries must be monitored while they
are being charged.
The maximum quick charging current specied for the respective cell type may not be exceeded.
If the battery heats up above 60°C while it is being charged, stop charging and let the battery cool down to approximately 30
- 40°C.
Never charge batteries that have already been charged, are hot or are not fully discharged. If a cell in a battery pack has be-
come particularly hot following a quick-charge process, this may indicate a defect in that cell. Do not use the battery pack any
more!
The batteries must not be modied. Do not directly solder or weld the cells.

General operating instructions
Method for Installation of Receiver
The receiver is to be installed with a foam rubber cushion to afford protection against jarring, in air-
craft models behind a strong rib and in a car or ship model in a place where it is protected against
dust and spray water. The receiver may not be mounted in direct contact with the hull or chassis as
this would allow motor vibrations and/or landing jolts to be transferred directly to the receiver. When a
receiver system is installed in a model with a combustion motor, all receiver parts should be installed
so as to prevent exhaust gases and oil residues from inltrating. This especially applies to the ON/
OFF switch, which is usually built into the model’s outside skin. Position the receiver such that con-
necting cables to the servos and the power supply are routed with a bit of slack
and that the receiver’s antenna is at least 5 cm away from any large metal parts or wiring other than
those proceeding from the receiver. In addition to steel, this also applies to carbon ber parts, servos,
electric motors, fuel pumps, any kind of cable and similar items. Optimally the receiver should be
placed at a readily accessible location that is well away from all other equipment. Under no circum-
stances may a servo cable be wrapped around the antenna or routed close to it.
Ensure that cables near the antenna cannot move about during ight.
Information on handling the transmitter
!
Attention!
Also while programming the transmitter, make sure that a connected motor cannot accidentally start. Disconnect the fuel
supply or drive battery beforehand.
Risk of re! Avoid every kind of short-circuit in all sockets of the transmitter! Use only the suitable connectors. In no case
the electronic component of the transmitter may be changed or modied. Due to licensing reasons, any reconstruction and/or
modication of the product is prohibited.
During transport protect the model and the transmitter from damages.

Routing the receiver’s antenna
The receiver and the antennas must be positioned as
far away as possible from any drive components. If
the model’s hull is made of carbon ber material, the
ends of the antennas should always extend outside
of the hull.
The orientation of antennas is not critical.
Nevertheless, a vertical (upright) installation of the
receiver’s antenna(s) is advantageous.
Servo installation
Always mount servos with the rubber vibration-damper parts provided. This is the only way of en-
suring some protection against excessively strong vibrations.
Installing linkage
Linkage must be installed so as to ensure unhindered and smooth movement. It is particularly im-
portant that all rudder levers are able to move to their full limits and are not blocked mechanically.
In order to be able to stop a running motor at any time, the linkage must be set to ensure that the
carburetor tap is completely closed when the joystick and trim lever are brought into their end idle
positions.
Pay attention that no metal parts rub against one another, e.g. as a result of moving the rudder,
of vibration, rotating parts etc. Metal-to-metal contact causes ‘static’ which can interfere with the
correct operation of the receiver.
Transmitter antenna orientation
The patch antenna is integrated in the rectangular front panel of the transmitter. This means that
‘aiming’ the transmitter at the model will have a positive effect on reception. However, when two or
more pilots using 2.4 GHz remote control systems are within 5 m of one another this can lead to
return channel overdrive which, in turn, will trigger a range warning much too soon. Increase your
distance between one another until the range warning ceases.
Pre-start checks
Before switching the receiver on, ensure that the throttle control is in the Stop/Idle position.
Always switch the transmitter on rst and then the receiver.
Always switch the receiver off rst and then the transmitter.
WARNING:
If this sequence is not maintained, and the receiver is still switched on when the
corresponding transmitter is switched to the ‘OFF’ position, then the receiver may
respond to other transmitters or general radio frequency noise. This can cause the
model to execute uncontrolled operations that may cause personal injuries and/or
property damage.

Range test
Perform checks for proper operation and range before any use. Secure the model adequately
in place and ensure that no one is in front of the model. Perform a complete functional test on
the ground and execute a complete simulated ight to rule out the possibility of system faults or
problems with the model’s programming.
You must refer to the instructions in the manual of the transmitter. Do not operate your model, ie
when ying or driving, without transmitter or receiver antenna. Ensure a tight t of the antenna.
Monitoring transmitter and receiver batteries
You must stop running the model to replace or recharge the transmitter’s battery no later than
when, as a result of the drop in battery voltage, the red status LED ashes and an acoustic
warning sounds. Check the status of batteries regularly, particularly the receiver’s battery. Do
not wait for the movements of controlled mechanisms to become noticeably slower. Replace
expended batteries before they cause problems. Always follow the battery manufacturer’s
charging instructions are adhere exactly to charging times. Never leave batteries unattended while
charging. Use your charger only in rooms equipped with a smoke detector for protection.
Warning: Never attempt to charge dry cell (non-rechargeable) batteries (risk of explosion).
All rechargeable batteries must be charged before every use. To avoid short circuiting, rst
connect the charger cable’s banana plugs with correct polarity to the charger and then plug the
charger cables into the sockets for the transmitter and receiver batteries.
Disconnect all batteries from the model when it is not to be used for an extended period of time.
Never use defective batteries, damaged batteries or different types of battery cells in combination.
Do not use combinations of old and new batteries or batteries from different manufacturers.
Capacity and operating time
The rule that capacity is reduced with every successive recharging applies to all batteries. Internal
resistance increases at low temperatures, further reducing capacity. As a consequence, the
battery’s ability to supply current and retain its voltage is reduced.
Frequent charging or the use of battery maintenance programs can also result in gradual loss of
battery capacity. Battery capacity should therefore be checked at regular intervals of not more than
every six months and the batteries replaced if performance is found to be signicantly decient.
Purchase only genuine Graupner batteries!
Interference suppression for electric motors
With all conventional electric motors, sparks are generated between the collector and brushes.
Depending on the type of motor involved, this may interfere more or less with the functioning of
the remote control system. The electric motors of a properly built system should therefore include
interference suppression. For electric drive models it is particularly important that every one of its
motors is equipped with proper interference suppression. Interference lters largely suppress such
disturbances and should always be installed. Follow the specic recommendations included in the
motor’s operating and installation instructions.
For further details about interference lters, refer to the Graupner RC main catalog or on the web
at www.graupner.de.
Servo interference lters for extension cables Order No. 1040
The servo interference lter is necessary when an extended-length servo cable is used. This lter
is attached directly to the receiver output. In critical cases a second lter can be attached to the
servo. Using electronic speed controllers Choosing the right electronic speed controller largely
depends on the power of the motor used. In order to prevent an overload or damage to the speed
controller, its current rating should be at least half of the maximum locked-rotor current rating of
the motor. Special caution is necessary in the case of motors referred to as ‘tuning motors’. Due
to the small number of coil windings, such motors can draw a multiple of their rated current in a

locked-rotor condition, leading to irreparable damage to the speed controller.
Electric ignition systems
Combustion engine ignition systems also produce interference that can adversely affect remote
control functioning.
Always supply power to an electric ignition system from a separate, dedicated battery.
Use only interference-suppressed spark plugs, spark plug connectors and shielded ignition cables.
Mount the receiver at an adequate distnce from ignition system components.
Static charges
Warning:
Lightening results in magnetic shock waves that interfere with the functioning of a
remote control system – even if the storm is miles away. Therefore …
… stop ying right away if a storm is approaching. Static charges gathered via the
antenna also represent a lethal hazard.
Please observe the following:
• In order to fulll FCC RF emission requirements for mobile transmitters, a distance of at least
20 cm must be maintained between the system antenna and any persons while this system is
being operated. Operation of this system at a smaller distance is therefore not recommended.
• To avoid disturbance caused by the electrical properties and emission characteristics of other
transmitters, maintain a distance at least 20 cm from other transmitters.
• To operate the remote control system, the transmitter unit requires the correct program setting
for the given country. This is necessary for compliance with various regulations such as FCC,
ETSI, CE etc. Follow the specic instructions on this provided with the transmitter and receiver.
• Prior to every ight, perform a complete functional test, range test and execute a complete
simulated ight in order to rule out any possibility of system faults or problems with the model’s
programming.
• Never program the transmitter or receiver while the model is being operated.

Binding:
In order to be able to establish a connection to the transmitter, the Graupner-HoTT receiver has
rst to be "bound" to "its own" Graupner-HoTT transmitter. This procedure is called "binding". You
can also select before BINDING, in the line TELEMETRY, whether the telemetry data should be
displayed or not (see "RF SET menu") However, "binding" is necessary only once per receiver-
transmitter combination, and has already been done at the factory with the devices that are
delivered in one set, so you have to perform the "binding" only with further receivers (and – can
repeat it any time – e. g. after a transmitter change). To do so, perform the following steps:
• Switch on the receiver and put it in binding mode, by pressing and holding the binding button
for 3 sec. (green and red LED on the receiver are ashing)
• Trigger the binding in the menu "RF SET", by pressing the Enter button in the line "Receiver"
• If the red LED of the receiver goes out within about 10 seconds and the green LED is illuminat-
ed, the binding process has been completed successfully.
• Your transmitter/receiver combination is now ready for operation.
If the red LED is still lit, the "binding" failed. In this case, repeat the whole procedure.

Range test:
Perform a range test of the Graupner HoTT 2.4 system, by observing the following instructions.
If necessary, look for an assistant when performing the range test.
Install the receiver, which preferably has already been bound to the transmitter, in the model.
Switch on the radio control and wait, until the red LED on the receiver is no longer lit. Now you can
observe the servo movements.
Place the model on level ground (paving, short lawn or earth), so the receiver aerials are located
at least 15 cm above the ground. This might require a support for the model during the test. Hold
the transmitter at hip-height, away from your body. However, do not point the aerial directly at the
model, but turn and/or angle the aerial tip so it stands vertical during operation. Start the range test
mode in the "RF SET" menu, by pressing ENTER in the line "RANGE TEST", which is now active
for 99 sec., after which it will be switched off automatically. You can also quit the range test mode
by pressing ENTER again in the line "RANGE TEST".
Walk away from the model, and move the sticks. If you detect an interruption in the link within a
range of about 50 m at any time, attempt to reproduce it.
If possible, switch on an existing motor, in order to additionally check the interference resistance.
Continue to walk away from the model, until you reach the point where perfect control is no longer
possible. Now, terminate the range test mode manually.
Now, the model should respond again. If this is not 100 % the case, do not use the system and
contact your Service at Graupner/SJ GmbH.
Perform the range test before each operation and simulate all servo movements which are part of
the normal operation. In order to guarantee a safe model operation, the range must always be at
least 50 m on the ground.
