3.2 PWM+SBUS/PPM signal output working mode
When the BLUE indicator is on , flight controller can be connected and works with GPS to
make true the RTL function of shipping boat or setup of mecanum wheel models
Short press ID SET two times with interval less than 1s, the indicator from BLUE to
RED ,meaning the working mode from SBUS/PPM signal output working mode to PWM
working mode .

Note of Antenna Installation
In order to maximize the signal transmission, it’s greatly advised that
1. Keep antennas as straight as possible, or the effective control range will reduce.
2.
Keep the two antenna in 90° angle as shown below
3. Big models may contain metal parts that influence signal emission. In this case. antennas
should be positioned at both sides of the model to ensure the best signal status in all
circumstances.
4. Antennas should be kept away from metal conductor and carbon fiber at least half inch
away and no over bending.
5. Keep antennas away from motor, ESC or other possible interference sources.
6. Sponge or foam material is advised to use to prevent vibration when installing receiver.
7. Receiver contains some electronic components of high-precision. Be careful to avoid strong
vibration and high temperature.
8. Special vibration-proof material for R/C like foam or rubber cloth is used to pack to protect
receiver. Keeping the receiver in a well sealed plastic bag can avoid humidity and dust, which
would possibly make the receiver out of control.
When all the above steps are complete, please turn off the transmitter and repower on to test if
the receiver is correctly bind with it.
