General commissioning
Note
As soon as the transmitter is switched on then the throttle position
is checked. If the throttle position is not in the motor-off area, then
the drive motor may start in an uncontrolled manner. This check is
performed by all the models with the setting "Motor at CH1 front/
back". The warning alarm "Throttle too high" appears. For this rea-
son in this case the RF module will not be switched on. This check
is performed for every model types. With helicopter models the
warning works only if you use a Motor-off programming or if a throt-
tle limiter is set.
!
WARNING
If you do not follow the afore mentioned instructions, the con-
nected drive motor can run accidentally when the transmitter is
switched on. Risk of injury! Always program a switch for motor
stop!
If the previously mentioned checks are passed, the RF module will
be activated when the transmitter is switched on and in the display
appears a selection indicator.
Select with the selection buttons of the right four way keys RF ON/
OFF. By tipping the SET button on "OFF" the RF module is switched
off.
The color of the lighting central LED changes to red and you are now

The symbol mean that the currently active model memory has
once been linked to a receiver but is presently not linked. (We have
turned the RF module off for example reasons.) If instead the trans-
mitter was switched on without turning off the RF module, the cen-
tral LED would light blue and the symbol would blink. Contempo-
raneously a warning acoustic signal is emitted until a connection is
established with the respective receiver. As soon as this connection
is established appears a a field strength indicator and the warn-
ing signal stops.
If the telemetry connection is established the respective indication
of the receiver signals strength

On the other hand, if the screen displays the symbol combination
and the center LED illuminates in red continuously then the cur-
rently active model memory is not "bound" to any receiver.
