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 sur-
face. 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. Doc-
tor.

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 sin-
gle 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 nec-
essarily 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 trans-
mitter 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 resis-
tance 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 trans-
mitter is switched on. In the display appears the symbol of a
memory card.
Otherwise, folders are created on the memory card ( repre-
sented 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 mem-
ory 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 struc-
ture 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-neutral-
izing.
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 rel-
evant 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.
