Receiver output
This function (Channel Mapping) is available if the line "Module" is
bound to at least one receiver. Here you can split the control chan-
nels of the transmitter to the bound receivers. You can also freely
select the channel order within the receiver. The control channels
coming from the transmitter will be assigned to a free selectable
output of the receiver.
Use the selection buttons to move to the desired receiver field.
Select the input to be assigned to another output. Tap on the SET
button. Set the desired channel. Confirm the selection by pushing
the SET button.
RF module
In this menu line the RF module of the transmitter is manually
switched on and off. This line is only available if a receiver is bound.
Range test
The integrated range test reduces the transmitter output so that a
control test at a limited distance can be performed.
Perform the range test before each operation and simulate all servo
movements that are part of the operation. In order to guarantee a
safe model operation, the range must be at least150 ft on the ground.
Place the model on a flat surface (cement, mowed lawn or ground)
so that the receiver antennas are at least 6 in above the ground. If
necessary, place a support underneath the model during the test.
Hold the transmitter at hip level at a slight distance from your body.
Keep the surface of the patch antenna of the transmitter in the direc-
tion of the model.
Start the range test by pushing the SET button. The time display "99
sec" will start the countdown. You will hear two acoustic signals
every two seconds. In the last five seconds, the acoustic signals will
be 3 each second.
During this time, move away from the model, while operating
the transmitter's control sticks. Let the control movements be
observed by a second person.
The range test can be considered as successful if there is no interfer-
ence in the control movements of the model within the 150 ft range.
After the end of the 99 seconds ,the transmitter switches again to
full transmission power and the green LED on the right of the main
switch lights again permanently.
If the range test has not been successful, verify the following condi-
tions:
 Is the power supply of the receiver OK?
