For your safety by handling the battery

CAUTION

 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 fire!

 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-flammable, heat-resistant and non-conductive sur­face. Combustible or highly flammable objects are to be kept
away from the charging area. Batteries must be monitored
while they are being charged.

 The maximum quick charging current specified 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
become 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 modified. Do not directly solder or

weld the cells.

 If handled improperly, there is a danger of fire, explosion, irri-

tation and burns. To extinguish a fire use: water, CO2, sand.

 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.

!

11 / 36

33032_jp_V1

 Always charge the battery fully.

 The maximum charging current permitted may not be

exceeded.

 Never leave the charger unattended when it is connected to

the power supply.

 Batteries may only be charged in rooms fitted with smoke

detector.

Special instructions

 To charge and discharge batteries, only use specifically

designed chargers/dischargers with balancer connector.

 The white connector (cell count + 1 pole) is designed for the

connection to a LiPo balancer or a battery charger as a sin­gle cell charger with a manual cell balancer. Always charge
the battery with the balancer connector.

Safety notes for stocking batteries

 Batteries may only be stored in non completely discharged

condition.

 The cell voltage should not fall below 1.2 V when stored for

a long time.

 Batteries may only be stored in dry rooms with an ambient

temperature of +5°C to +25°C.

 Stock the LiPo batteries with a cell voltage of about 3,8V. If

the cell voltage falls below 3 V, then the battery must be nec­essarily charged. Deep discharge and storage in discharge
status (cell voltage < 3V) make the battery useless.

 Charge and transport your batteries always in a safety bag.

DSCsocket

Connection socket for flight simulator or T/P systems

The standard two-pin DSC socket on the transmitter functions
as a TRAINER or PUPIL socket as well as an interface for flight
simulators or other external RF modules.

To ensure a correct DSC connection, observe the following:

1. Perform any necessary adaptations in the menu.

2. When using the transmitter with a flight simulator or during
the teacher-pupil operation, set the On/Off switch always on
the "Off" position. Only in this position even after connecting the
DSC cable the RF module of the transmitter remains inactive.

The status LED is constantly red and in the display will appear
DSC.

In the mc-32 HoTT transmitter upper display appears the trans­mitter logo.

The transmitter is now ready for use.

Note

If the transmitter is used as teacher transmitter it has to be switched
on before connecting the proper cable.

3. Connect the other end of the connecting cable to the device
while observing the relevant operating instructions.

Note

Make sure that all the plugs are securely inserted in the respective
sockets, and only use the provided plug-in connectionswith a 2-pin
jack plug on the DSC side.

4. In the "Transmitter setting" submenu, you can set one of the
following modes in the "DSC output" line depending on the
number of functions to be transmitted: PPM10, PPM16, PPM18
and PPM24. Default setting: PPM10.

16 / 36

33032_jp_V1

ATTENTION!

When your transmitter is directly connected to a desktop computer
by a connecting cable (DSC cable) and/or a computer interface is
connected to your simulator, the transmitter may be destroyed
byelectrostatic discharge. This type of connection should therefore
only be used if you protect yourself from electrostatic discharge
while operating the simulator by wearing a commercially available
grounding armband. Graupner therefore strongly recommends only
using wireless simulators.

Memory cards

Micro SD cards up to 2 GB and micro SDHC up to 32 GB are
compatible memory cards.

Our recommendation: For a normal use a memory card with a
storage capacity of up to 4 GB is sufficient.

Inserting and removing the memory card step by step:

Switch off the transmitter.

The memory card slot is located in the left provided connections
of the transmitter.

To insert:

Push the SD card as deep as you need to win the spring resis­tance of the slot.

To remove:

Push the SD card slightly toward the card slot to unlock it and
then remove it.

The included memory card is ready for use as soon as the trans­mitter is switched on. In the display appears the symbol of a
memory card.

Otherwise, folders are created on the memory card ( repre­sented in the transmitter display by a permanent filling from left
to right memory card). When the animation finishes, the inserted
memory card is ready for use.

You can connect the memory card to your PC by using a mem­ory card reader. Copy the data downloaded from the transmitter
page on the web site in the related folder of the memory card.
Insert the memory card in your transmitter.

Data recording/Data saving

The data recording in the SD card is linked to the flight timer. If
it is started, the data recording starts as well and it stops when
the flight timer is stopped.

The data writing on the memory card is remarked by the symbol
of the "filling" of the memory card with black from left to right.

17 / 36

33032_jp_V1

After the installation of the memory card, there is a folder struc­ture in it. These folders are actually empty.

Finally, the log files are saved in subfolders called "Modelname"
named according to the structure 0001_year-month-day.bin. If a
model memory is still nameless, the corresponding log files are
saved in a subfolder entitled "NoName".

In the folder "Models" are saved the exported model memories.

The data can be evaluated on a compatible computer using the
programs found on the downloads page for the transmitter
under www.graupner.de.

Commissioning

Opening/closing the transmitter housing

The transmitter should be opened only in the following cases:

 If a self centering stick has to be converted in non self cen-

tering

 If a non self centering stick has to be converted in self cen-

tering

 To set the control stick centering force

Open step by step

Before opening the housing switch the transmitter off.

Push both housing base latches in the opposite the direction of
the arrow marks, toward the inside, to their limits.

Now tilt the transmitter somewhat to the rear so the housing
base can flip open and can be unhooked.

!

CAUTION

Never switch the transmitter on while the housing is open! Do not
touch the electronic boards.

Closing step by step:

Hook the transmitter's housing base to the underside.

To lock the transmitter bottom case, flip the base closed then
push both latches toward the outside.

Sticks conversion

Neutralization

Both control sticks can be set from neutralizing to non-neutral­izing.

Neutralizing step by step:

Locate in the left control stick gimbal the screw surrounded by
a white circle in the picture.

Turn the screw toward the inside of the transmitter until the rel­evant control stick can move freely from stop to stop, or turn it
outward until the control stick resets itself independently.

Note

The right control stick gimbal is specular to the left one, so that here
the screw is located right under the middle.

21 / 36

33032_jp_V1

Brake spring and ratchet

Locate the screws indicated by a white circle in the picture.
The outboard screw of the two marked in the figure adjust the
braking force.

The inboard screw adjusts the strength of the ratchet for the
respective control stick.

Note

The right control stick gimbal is specular to the left one, so that here
the screws are located left on the top side.

Control sticks centering force

The control sticks' restoring force can also be adjusted. The
adjustment is located next to the return springs.

By turning the respective adjust screw the spring force can be
adjusted.

Right turn = return harder

Left turn = return softer

Brackets for transmitter belt

A stable transmitter hanger for fastening neck straps is standard
equipment on the mc-32 HoTT transmitter.

Installing the metal brackets:

Push both brackets inward a bit near where they are engraved.

Turn them upward by 90 °. The brackets will automatically lock
into position.

If you have a neck strap fastened to the holder bracket with key­rings, first press lightly on the right holder bracket to release its
latch. So it can be folded down. Use the same procedure for the
left bracket.

Afterward push both brackets simultaneously into the recess.

33032_jp_V1

Installation of switches, switch modules and knob modules

There are a total of 20 holes in the transmitter's housing avail­able for mounting accessory modules.

!

WARNING

To be safe, always disconnect the transmitter battery before instal­lation to avoid short circuit conditions.

Be sure to pay attention that soldered points on the transmitter board
do not come into contact with metal objects!

Unoccupied holes in the transmitter's housing are closed with
blind plugs. These can easily be pulled out from the outside.
Insert the accessory switch, etc. through a hole in the housing
from the inside.

Fixing the switch, switch module and knob module

The fixation is made by screwing a nut on the thread on the
upper part of the switch. These will pass though the housing and
tightened with a suitable wrench. The Graupner trim nut wrench
is well suited for tightening down these nuts.

Aligning the antenna

The removable, articulated antenna is to be screwed into the
ball-joint connector then aligned by hand.

Do not point the antenna directly to the model. Turn and bend
the antenna so that during the use it is oriented to a side (see
picture on the left) or alternatively turn it perpendicularly to the
top.

CAUTION

When screwing in the antenna, pay attention that the centre pin in
the antenna socket does not get bent or pressed back in the socket.

Switch on transmitter

Safety query

When the transmitter is switched on the throttle position is checked.
(Premise: Model type "winged" "Motor at ch1 front/back" or model
type "Heli" is selected) If the throttle stick is set out of the minimum
position, the warning message "THR too high!" appears and the RF
module remains off for safety reasons.

!

WARNING

If you do not follow the afore mentioned instructions, the connected
drive motor can run accidentally when the transmitter is switched
on. Risk of injury! Always program a switch for motor stop!

Throttle

too

high!

23 / 36

33032_jp_V1

Otherwise the RF module will be activated when the transmitter
is switched on and in the display appears a selection indicator.

Select with the selection buttons of the right touch pad RF ON/
OFF. By tipping the SET button on "OFF" the RF module is
switched off.

The color of the lighting central LED changes to red and you are
now in the transmitter main menu display.

The symbol

mean that the currently active model memory has
once been linked to a receiver but is presently not linked. (We
have turned the RF module off for example reasons.) If instead
the transmitter was switched on without turning off the RF mod­ule, the central LED would light blue and the symbol

would
blink. Contemporaneously a warning acoustic signal is emitted
until a connection is established with the respective receiver. As
soon as this connection is established appears a a field strength
indicator

and the warning signal stops.

If the telemetry connection is established the respective indica­tion of the receiver signals strength so as the actual
receiver power supply voltage.

On the other hand, if the screen displays the symbol combina­tion

and the center LED illuminates in red continuously then

the currently active model memory is not "bound" to any receiver.

Binding

Explications about the binding process can be found in
the Part 2 of the manual.

For a transmitter commissioning the receiver must be bound to
the transmitter. This binding process is necessary for the opera­tion of the model!

The exact sequence of the binding operation is described in the

in the SD card by a PC.

Firmware update/Changing the display language

Note

Before each update, check the transmitter battery charge or charge
it as a precaution, and save all model memories so that they can be
restored if necessary.

Note

Follow the "Firmware update step by step" manual steps from the
section "Firmware update" "Update per memory card".

30 / 36

Firmware update step by step:

Move with a short pressure on the SET key to the selection page
of the option "FIRMWARE UPDATE".

Select the firmware version with the selection keys.

Confirm by pushing the SET key.

The storing in the transmitter memory will start:

When the counter reaches the storing amount the storage pro­cess is finished and the message "Firmware upgrade success!"
appears. The transmitter reboots and it is ready for use.

Stick calibration

If the center position of your self-neutralizing control stick does
not precisely correspond to 0% control travel, you can check
and correct it as follows:

Stick calibration step by step:

Move to the "Model select" menu and initialize a free model
memory.

Move to the "Servo display" menu, pressing simultaneously the

keys in the left touch pad, without any interim change to trim

settings or other program settings.

In this menu point you can check if your sticks are correctly cen­tered. Bring then all the sticks in the middle position.

One after the other, put both sticks into each of their four pos­sible limit positions without exerting force at the limit position
and check if the value are between -100% and +100%. For
example, if control 2 is at its right limit and the other three other
control stick functions are in their respective middle positions,
then your transmitter's display should look like the one shown
on the left.

Regardless of the number of self-neutralizing control stick func­tions available on your transmitter, if these checks produce four
0% results and eight 100% results, then your transmitter's con­trol sticks are optimally calibrated. You can terminate this pro­cess and then, if appropriate, delete the model memory just cre­ated.

If you note that the sticks do not reach the desired values, move
to the "Stick calibration" line in the "HIDDEN MODE" menu and
tip on the SET key.

The flashing arrows indicate in which direction you have to push
the sticks.

Confirm by pushing the SET key.
