4. FTr12B Receiverhttp://www.flysky-cn.comCopyright 2020 Flysky Technology co., ltd Binding 1. 1. Press and hold the receiver BIND button [22] while powering on the receiver, release the BIND button after receiver is powered on, the LED [20] on the receiver will flash rapidly;

2. Put the transmitter into bind mode;

3. The binding process is complete when the LED on the receiver stops flashing and is on continuously. If a transmitter that has had its radio frequency (RF Standard) set to AFHDS3 1 way (please refer to your transmitter user manual) enters bind mode, the receiver LED will instead flash slowly. Exit bind mode on the transmitter and if the receiver LED stops flashing and is on continuously, the binding process is complete. 4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise. Forced update 1. 2. 3. Failsafe If after a firmware update is performed and the transmitter is unable to bind to the receiver, the receiver may need to be put into forced update mode. 1. Power on the receiver while pressing the BIND button [22] for then approximately ten seconds until the LED [20] flashes three times,release the BIND button. 2. Go to the RX Setup menu on your transmitter and select RX Update. 3. When the receiver LED flashes slowly, the update is successful. This function protects your vehicle by preventing unexpected behaviors in case of signal lost. Users should always input Failsafe parameters before operating their vehicles. If the Failsafe function has not been set on the transmitter and signal lost occurs, the receiver will continue to operate and maintain all output value at the last received instructions from the transmitter. If the Failsafe parameters on the transmitter has been set, the receiver will set output values according to user parameters during signal lost. Compatibility AFHDS3 PL18NB4NB4 LiteFRM302 . The FTr12B receiver is compatible with all AFHDS 3 transmitters and RF modules (including PL18, NB4, NB4 Lite, FRM302 etc.) 1 Attention:

or loss of control. Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury. Make sure the receiver's battery is disconnected before turning off the transmitter, failure to do so may lead to unintended operation Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise. Do not power on the receiver during the setup process to prevent loss of control. Keep the receiver's antenna at least 1cm away from conductive materials such as carbon or metal. FTr12B Receiverhttp://www.flysky-cn.comCopyright 2020 Flysky Technology co., ltd Certification FCC Compliance Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
