Setting up the receiver
The setup procedure has 3 functions:
Mode I
- lock the receiver to the transmitter frequency
Mode II
- disable failsafe
Mode III
- enable failsafe
Failsafe ensures that the servos and/or ESC are set to a predetermined position within 0.5s after a loss of
reception. Without failsafe servos will respond erratically resulting in a loss of aircraft control in case
reception is lost.
Set up process
1. Turn on transmitter with the antenna extended
2. Power up the receiver. The receiver LED will flash 2 times quickly
3. Press the scan button on the receiver for 2 seconds
4. The LED will flash 3 times meaning the receiver is ready for the set up process (should it blink 2 times,
then press the button again for 2 seconds).
Keep a careful eye on the LED. The receiver will cycle through 3 modes successively.
It may be helpful to do the setup in a dark environment so you can better see the LED flashing.
Mode I
- Short lit followed by a short dark period, repeated 3 times
sequence will repeat 3 times. Pressing the button in this mode will start the frequency locking process. If the
button is not pressed, mode I will be entered.
Locking to the transmitter frequency
1. Turn on the transmitter with the antenna extended.
2. Turn on the receiver. The LED will blink 2 times. If the LED remains lit then the receiver is receiving
correct commands from a transmitter.
If the LED goes out then the receiver is not receiving any correct commands, in which case you should set
it up again...
3. To set it up, press the scan button for 2 seconds, then release it. The LED blinks 3 times now (should it
blink 2 times, then press the button again for 2 seconds). While in mode III , press the button shortly.
If the LED begins to blink quickly it means that the receiver is searching for a valid signal.
Wait for 2-3 seconds for the search to complete. Once the receiver is locked to the transmitter, the LED
will flash 2 times and then remain lit. If the LED goes out again, check the transmitter.
4. After the receiver has locked, if you don't change frequency, the receiver will work whenever you
connect it to the power. No need to relock.
Caution: when locking your receiver, please ensure only your own transmitter is working and put your
receiver close enough to your transmitter.
Mode II
- Long lit followed by a long dark period, repeated 3 times
sequence will repeat 2 times. Pressing the button in this mode will disable the failsafe function. If the button
is not pressed, mode II will be entered.
Disabling the failsafe
1. Turn on the transmitter with the antenna extended.
2. Turn on the receiver. The LED will blink 2 times. If the LED remains lit then the receiver is receiving
correct commands from a transmitter.
3. To set it up, press the scan button for 2 seconds, then release it. The LED blinks 3 times now (should it
blink 2 times, then press the button again for 2 seconds). While in mode II, press the button shortly to start
