2) Convenient to upgrade – no need to open the receiver’s case when upgrade D8R-II;

3) Two switchable PPM modes - FS mode and HS mode;

4) Alarm warning on low voltage, poor reception, etc.

2. Set up

2.1 Bind procedure

1) Ascertain that the transmitter is in the PPM mode. Turn off the transmitter.

2) Turn on the transmitter while holding the F/S button on the transmitter module (Ensure that both

switches on the transmitter module are OFF when using D8R-II in two way mode). Release the button.

The RED LED on the transmitter module will flash, indicating the transmitter is ready to bind to the

receiver.

3) Connect battery to the receiver while holding the F/S button on the receiver. The LED on the

receiver will flash, indicating the binding process is completed. Turn off both the transmitter and the

receiver.

4) Turn on the transmitter and connect the battery to the receiver. The RED LED on the receiver

will indicate the receiver is receiving commands from the transmitter. The receiver/transmitter module

binding will not have to be repeated, unless one of the two is replaced.

Warning: Battery or servos are NOT to be plugged into side ports (A1/A2/Rx), otherwise

damage may occur.

2.2 Range check

A pre-flight range check should be done before each flying session. Reflections from nearby metal

fences, concrete buildings or trees can cause loss of signal both during the range check and during the

flight.

The following steps are to be followed to perform the range check of the model before the flight:
