Range test
The integrated range test reduces the transmitter output so that
you can perform a function test at a distance between 5 and
about 10 m.
Perform the range test for the Graupner-HoTT system according
to the following instructions. It is useful to have an assistant to
help you with the range test.
Switch on the transmitter and the copter then wait until the green
LED on the copter lights. You are now able to monitor control
movements.
Place the model on a flat surface (cement, mowed lawn or
ground) so that the receiver antennas are at least 15 cm above
the ground. It may therefore be necessary to place a support
underneath the model during the test.
Hold the transmitter at hip level at a slight distance from your
body.
You can start the range test process by pushing simultaneously
the "SPEED + SNAP" buttons.
The red status LED on the transmitter will start to blink quickly
and a signal tone is emitted twice each two seconds.
After the 90 seconds range test, the transmitter switches back
to full output, and the signal tone stops.
You can stop the range test in every moment by pushing the
POWER button.
During the 90 seconds, walk away from the model and move
the sticks. If you detect an interruption in the link within a range
of about 5 - 10m at any time, attempt to reproduce it.
Move further away from the model until it does not respond per-
fectly. Move further away from the model until it does not respond
perfectly.
At this location, wait for the remainder of the test period with the
still operable model. The model should still react to control com-
mands once the range test is finished. If this is not 100% the
case, do not use the system and contact our Service depart-
ment.
Perform a range test before each flight, and simulate all control
movements that could occur during the flight. In order to guar-
antee a safe model operation, the range must always be at least
5 - 10m on the ground.
Attention
Never start a range test on the transmitterduring normal model
operation!
