Binding & Forced Update & Failsafe

Binding

To ensure good signal strength, make sure the receiver antenna is as far away from any metal parts when installing the receiver.

1. Insert the binding cable into the receiver's BIND port. 2. Plug the power cable into any other port, and the receiver's LED will start to flash quickly indicating that it has entered bind mode. 3. Put the transmitter into bind mode; (See the transmitter's instruction manual for more information.) 4. Binding is successful when the receiver's LED starts to flash slowly. Remove the power and bind cables from the receiver. If the transmitter is bidirectional the reciever status indicator will not fash slowly. 5. Reconnect the power cable to the receiver. 6. Check to make sure that the transmitter and receiver are working as expected, if there are any issues or unexpected operation follow the steps above to bind again.

Forced Update

After the transmitter is updated, if the code cannot be matched with the receiver, it is necessary to update the receiver. 1. Short circuit bind and its separated signal pins with bind cable;（It has been signed in the Receiver overview part） 2. Power on the receiver to enter the update mode（LED light of the receiver changes from 3 flash and 1 off), unplug the bind cable, and select forced update at the transmitter. 3. The LED light of the receiver changes from 3 flash and 1 off to slow flash, the update is completed.

Failsafe

The failsafe function is used to output the channel according to the out-of-control protection value after the receiver loses its signal and is out of control to protect the model and personnel.

• If the transmitter has not set the output of the failsafe channel value, after the receiver enters the out-of-control state, PWM, PPM, i-bus will not output, and the S.BUS will keep the last output; if the transmitter is set with the failsafe, follow the transmitter channel setting value Output.

  4. Do not power on the receiver during the setup process to prevent loss of control.

I love how tiny they are, can put them in 1/6 1/8 1/10 1/12 1/16 1/18 they fit well. The reception so great, my rssi doesn’t drop out at longer distances and the precision made case is a nice touch. One of my favorite ground RX. Performs well and I wish they were less expensive.

I got 3 extra of these receivers to go with my Flysky Noble NB4. I haven't experienced even the slightest glitch with these. I really like the built in antenna and small size (similar size or smaller than some of the major brands). They also have a bus port that you can plug in multiple telemetry devices piggybacked onto each other while only taking up one connection on the receiver. Too cool!
