Preliminary notes
In its default state the mc-22s transmitter is program-
med to the PPM18 transmission mode, which suits
“FM-PPM” type receivers. If you have purchased
a standard radio control set on the 35 or 40 MHz
bands, you can immediately operate the supplied
R16
SCAN receiver using this transmission mode.
In addition to PPM18 the following transmission mo-
des can be selected:
• PCM20 mode for all GRAUPNER/JR “mc” and “DS
mc” type receivers.
• SPCM20 mode for GRAUPNER/JR “smc” type re-
ceivers.
• PPM24 mode for the GRAUPNER/JR DS 24 FM S
receiver.
This mode switching facility enables the mc-22s
transmitter to operate all GRAUPNER receiving sys-
tems supplied to date, i.e. all receivers supplied with
PPM-FM and PCM transmitters (with the exception of
the FM6014 / PCM 18).
If you do not own a “PPM18” type receiver, this
means that you fi rst need to change the type of mo-
dulation to suit the receiver you wish to use. If you ne-
glect to do this, the transmitter will not operate the re-
ceiver correctly.
The transmission mode can be set in the »Base se-
tup model« menu (description: page 50) for the cur-
rent model, or pre-set in the »Basic settings« menu
(description: page 117) for all future model memo-
ries.
As standard, the two proportional sliders in the
transmitter’s centre console are connected to sockets
CH6 and CH7 on the transmitter circuit board. For the
purposes of further programming it does not matter
which socket numbers are assigned to the three swit-
ches on the “Multi Switch Board”.
Which crystals can be used?
The mc-22s requires no plug-in crystals. The trans-
mission channel is selected by software: see the next
page.
Battery charged?
When you fi rst take delivery of your transmitter, the
battery will be in the discharged state, so you must
fi rst charge it as described on pages 10 … 12. If you
do not do this, the battery will soon
fall below the pre-set threshold vol-
tage (approx. 9.3 V), and you will
see and hear a warning signal to
remind you to recharge it.
Aerial fi tted?
Never switch the transmitter on unless the aeri-
al is screwed in. Even for prolonged testing you
should always fi t the aerial and extend it fully,
otherwise the transmitter may malfunction, with pos-
sible damage to the RF module.
When you wish to control a model it is fundamen-
tally essential to screw the ten-section telesco-
pic aerial into the transmitter and extend it fully.
Transmitter fi eld strength is at a minimum in an ima-
ginary line extending straight out from the transmit-
ter aerial. It is therefore fundamentally misguided to
“point” the transmitter aerial at the model with the in-
tention of obtaining good reception.
Selecting the language
The mc-22s transmitter offers the facility to select any
of four languages:
• German
• English
• French
• Italian
To change the menu language, hold the HELP button
pressed in when you switch the transmitter on; you
will then see this display:
, / * . 1
You can now select the desired language by turning
the rotary control. A brief press on the rotary control
(or pressing the ENTER button) confi rms your choice.
All settings stored in the transmitter are retained
in full when you switch languages.
Batt must
be re-
charged!!
