Receiving system
The mc-22s radio control set is supplied complete
with a PLL-SCAN narrow-band FM superhet receiver
on the 35 / 35B MHz band or the 40 / 41 MHz band.
The following section describes how to set the recei-
ver channel to match the transmitter’s channel. The
approved channels at the time of going to press are
listed in the table on page 168.
As mentioned on page 21, the mc-22s transmitter is
pre-programmed to what is known as
PPM18 mode,
which suits receivers of the “FM-PPM” type. 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 transmissi-
on mode.
If in the meantime you have changed the transmissi-
on mode, and you wish to use the receiver supplied
in the set, your fi rst task is to set the transmitter back
to PPM transmission. Next you should select the desi-
red channel on the transmitter, as described on the
preceding page.
However, you must not activate the
channel on the transmitter until you have checked ca-
refully that no other pilot is fl ying his model on your
chosen frequency.
When you are confi dent of this,
switch the receiver on. You will see a blue LED light
up on the receiver, indicating that the unit is (basical-
ly) ready for use.

Setting the receiver to match the transmitter
channel
1. Prepare the transmitter ready for use, with the ae-
rial fi tted and extended, and place it in the imme-
diate vicinity of the receiver. The scan program
which is run next binds the receiver to the most
powerful transmitter signal, so you must ensu-
re that no other radio control transmitter is located
very close to your receiver.
2. Locate the push-button marked “SCAN” on the re-
ceiver, and use a tool such as a ball-point pen to
hold the button pressed in until the LED goes out;
this takes about three seconds.
3. When the LED is extinguished, press the SCAN
button again immediately: the LED now fl ashes at
a high rate. This indicates that the “Scan” process
is under way. As soon as the receiver “fi nds” the
transmitter frequency, the LED will light up again
constantly. The receiver stores this channel, so
that you do not need to repeat the process each
time you switch the receiver on; you only need to
do this if you change channels.
4. If the LED fl ashes slowly after a few seconds, it
is unable to lock onto the transmitter frequency.
Check the transmitter, then repeat steps 1 to 3.
Always carry out a range check with the model on
the ground before every fl ight.
Note:
If you wish to connect a servo in parallel with the re-
ceiver battery, i.e. to the socket on the R16
SCAN
re-
ceiver marked “8 / Batt”, you need to use a Y-lead, Or-
der No.
3936.11 or 3936.32 .
Please read the information on installing the receiver
and receiver aerial on pages 3 to 5 of these instruc-
tions.
If you wish to use a different GRAUPNER recei-
ver (Synthesizer or crystal-controlled), please note
that you must set the appropriate transmission mode
(PPM18, PPM24, PCM20 or SPCM20) on the trans-
mitter; the frequency band and channel number of the
receiver must also match those of the transmitter. Ple-
ase refer to the main
GRAUPNER FS catalogue for
details of the full range of receivers.
The R16
SCAN
receiver is fi tted with polarised connec-
tor sockets, so that the servos and battery can only
be connected the right way round. Genuine
GRAUP-
NER plugs feature a slight chamfer on one side to
match the sockets. Connect the receiver battery to
the receiver socket marked “Batt” via an ON / OFF
switch harness.
