Using the transmitter for the fi rst time
Selecting a channel
Switching the transmitter on / selecting a channel
Every time you switch the transmitter on you must
fi rst confi rm to the integral Synthesizer system that
you wish to use the set frequency. This takes the form
of a security query, intended to prevent you switching
the system on accidentally while the transmitter is set
to the wrong channel. The software asks you to con-
fi rm: “HF off / on”. The last set channel is initially high-
lighted (inverse video – black background) and fl as-
hes:
C61
HF off
switch on Channel
N O Y E S
è
If you wish to activate this channel, use the rotary
control to move to “YES”, and press
ENTER , or press
the rotary control briefl y; this switches the RF module
on with the set channel. If not, move to the arrow „
“
symbol. Press the rotary control or the ENTER button
to take you to the Channel Select list. The channels
available at that point vary according to the RF modu-
le currently fi tted:
Frequency band Channels
35 / 35 B MHz band 61 … 80/281, 282 and
182 … 191
40/41 MHz band 50… 92/400 … 420
K61 K62 K63 K64 K65 K66
K67 K68 K69 K70 K71 K72
K73 K74 K75 K76 K77 K78
K79 K80 K281 K282 K182 K183
K184 K185 K186 K187 K188 K189
K190 K191
Note:
Channels 281 and 282 in the 35 MHz band, and all
channels in the 41 MHz band, are not approved for
use in Germany. Please refer to the frequency table
on page 168, which lists the channels valid in the Eu-
ropean continent at the time of going to press (infor-
mation not guaranteed).
Use the rotary control to select the channel you wish
to use. However, please check before you do this that
no other model fl yer is operating a radio control sys-
tem on the channel you intend to use. Press the ro-
tary control,
ENTER or ESC to confi rm your choice,
and the screen reverts to the previous screen page:

Now switch the RF module on as previously descri-
bed, by moving the highlighted square to “
YES ”. The
selected channel number now appears (no longer
fl ashing) in the basic display:
#01 0:00h C73
10.3V
0:00h
0 0 0 0

The transmitter is now ready for use.
If you wish to change the channel again, the transmit-
ter must fi rst be switched off, then on again.
On page 46 you will fi nd a description of the basic
procedure for initially programming a new model me-
mory; helpful programming examples are in the sec-
tion starting on page 120.
Note:
The RF-Synthesizer module is connected to the
transmitter circuit board by means of two cables. If the
cables are not plugged in correctly, or if the 4-pin plug
is withdrawn in order to install a Pupil module (see
page 163), the transmitter switches directly to the
basic display when switched on. Instead of a channel
number, the screen now displays the fl ashing symbol
“C––” ; in order to indicate that the RF module is not
ready for use:
#01 0:00h C

Never, ever, switch off the transmitter when you
are fl ying a model! If you do, you run a serious
risk of losing the model, as you will be highly un-
likely to be able to re-activate the RF signal quick-
ly enough, since the transmitter always responds
with the security query “RF signal on YES / NO”
when switched on.
