The transmitter is now ready for use.
The following channels are available:
Frequency band Channels*
35/35B MHz band 61 … 80 / 281, 282
also 182 … 191
40/41 MHz band 50… 92 / 400 … 420
* 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 206, which lists the chan-
nels valid in the European continent at time of going to press
(information not guaranteed).
You must now switch the transmitter off, then on
again, in order actually to switch to another channel.
The basic procedure for the initial programming of a
new model memory is described on page 58, and in
the section starting on page 158 in the programming
examples.
W A R N I N G:
NEVER, UNDER ANY CIRCUMSTANCES, SWITCH
THE TRANSMITTER OFF WHEN YOU ARE FLYING
A MODEL AIRCRAFT! IF YOU DO, YOU RUN A SE-
RIOUS RISK OF LOSING THE MODEL, AS YOU
WILL BE HIGHLY UNLIKELY TO BE ABLE TO RE-
ACTIVATE THE RF SIGNAL QUICKLY ENOUGH
WHEN YOU SWITCH ON AGAIN, SINCE THE
TRANSMITTER ALWAYS RESPONDS WITH THE
SECURITY QUERY “RF SIGNAL ON YES / NO”
WHEN SWITCHED ON.
