RF SET

In the RF Set menu you will manage all RF and
Telemetry communications between the radio and
receiver as well as binding your model to the radio.

BINDING

You can bind in total 4 receivers to the mz-32. The
bindin g process requires y ou to place the re ceiver in
bind mode, which can be done by pressing the SET
button on the receiver. After 2-3 seconds, you can tap
the bind button on the radio.

You need to bind RX1 first. When binding has been

successful th e Rx column will show the channel count
of the receiver and below in small letters the current receiver firmware version. For
example, a GR-24 will show as R12 and a GR-12L will show as R6.

Depending on the r ecei ver mod el you may nee d to f oll ow a sl ightl y dif ferent procedure to
successfully bind the receiver to the radio.

Bind Method A:

Press the SET button and keep it pressed for 2-3 seconds and press the bind button on the
radio.

GR-12/GR-18/GR-24 PRO/GR-16(L)/GR-24(L)/GR-32(L):
Green LED on – Receiver bound
GR-12L:
Red LED off – Receiver bou n d

Bind Method B:

Receiver goes automatically into binding mode (Flight Controllers after 15 seconds with
blinking red LED)

GR-10C/GR-12SC & SH/Falcon 12/Alpha 110/S1038, S1039
Red LED off – Receiver bou n d

Notes:

 If binding was not successful, re peat the bind procedure.
 Make sure that the receiver is at least 50cm/2ft away fr om the radio.
 Verify that the power source is sufficient to power the receiver.
 Make sure that the power polarity is properly connected. The GR-12 6 channel

receivers require that the negative wire is facing up.

 Verify that the bind SET button is properly presse d.

RX

Tap on the selected blue Rx field (a receiver must be bound) and a dialog will show with
the available channels and channel numbers for that recei ver. Here you can remap the
channels or assign a digital switch output by tapping on the icon next to the channel
number.

Tap on the channel you want to remap and use the arrow keys to map the channel to
another channel.

Tapping on the Reset button will restore all channels to default.

T.Sel (Telemetry Select)

Tap on the rec eiver which you want to desi gnate as the acti ve telemet ry receiver. The re
can be only one telemetry receiver active at any time.

Modulation

The default modulation is set for HoTT (Hopping Telemetry Trans mission)

Page 7 of 42 Help-Ref-EN-V1.0

Graupner mz-32 Help Reference Manual

RF Transmit

Default is set to off. Tapping the off field will turn the RF to on. If no receiver is found the
radio will sound an error and the Graupner front logo wil l blink in blue.

Auto RF On

Setting this field to on will activate the RF immediately after the model is loade d bypassing
the RF On/Off dialog shown on startup when the Auto RF is switched to Off.

Bind Group

For an unboun d model memory , the defaul t is the next free bi nding group. However, as
long as the model memory is unbound, this specification can be changed by tapping the
icon on the “Bind Group” field. You can select from the following options:

„Global“ enables the receiver to respond to the transmitter signal on a non-exclusive basis.
What this means i s that any other receiver that is bounds as global will respond to the
transmitter signal of another model memory that was also bound as global. This can be
used in sit uation s where for ex ample y ou have m ultipl e model s that are a ll th e same and
do not need different model memory settings.

„Group“ enables the receiver to respond exclusively to the group ID assigned during
binding. For example, if you bind a re ceiver to bind gro up A0, that receiver will not respond
to a signal from the transmitter o f a model memor y that was bound global or , for ex ample,
as group C2.

You can bind another model memory also under bind group C2, which will result in one
model memor y sh a ring two receivers under a single bin d . Wh en b ot h r eceivers ar e t u rned
on, they will respond simultaneously to the same control inputs of the transmitter.

The use case for this is, for example, during competition when one airplane becomes
inoperative and you would like to continue the contest using an identical airplane without
switching model memories on your transmitter to avoid losing time. All you need to do is
power the other airplane and wait for the receiver to esta bl ish the bind.

Range Tes t

When the range test starts, the output o f the transmitter decreases significantly. A practical
functional test can therefor e be perform ed at a di st an c e of less than 1 0 0 m . A fter the end
of the range test, the transmitter switches back to full output power and the range test
signal tone stops.

Range test step-by-step

Verify that the receiver a nd transmitt er are communicating properly and that all control
surfaces are functional.

Place the model on a flat surface (cement, mowed lawn or ground) with the receiver
antenna at least 15 cm above ground.

Hold the transmitter at hip level at a slight distance from yo ur body.
Start the range test in the „RF Set“ menu by tapping the icon in the “Range Te st” field.
The time display begins to count down and a beep will sound throughout the entire range

test.
Move away from the model within the given 99 seconds range test and move the contr ol

sticks while maintaining visual contact.
If you notice an inter ruption in the connection at any time within a distance of about 50 m

/ 160 ft, try to reproduce it.
If possible, switch on an existing motor, to additionally c heck the interference resi st an c e.
Carry out the extended range test befor e star ting up your model, s imulating all the co ntr ol

movements oc curring in practi ce. To guarantee a saf e model operation, t he range must
always be at least 50 m / 160 ft on the ground.

Telemetry Speed

In those si tuations wh ere, for exam ple, two ai rplan e models are ab out to be op erated at
close proximity to another controlled by two separate transmitters, you may choose to
reduce or eliminate the telem etry back channel of one of the model s to avoid potential
interference. Situations that may need to be evaluated include drones that have a separate
transmitter for control and camera operations, or airplanes that tow or carry other
airplanes, can be all pick up interference from the telemetry downlink transmission.
Experiment with the proper telemetry period value for your situation.

You can redu ce the amou nt of telemet ry data tran smitted back f rom the recei ver to the
radio as follows:

 Always: Transmits telemetry data with each data packet.
 4 Times: Transmits telemetry data each 40ms
 8 Times: Transmits telemetry data each 80ms
 Off: No telemetry data is transmitted.
