FLYSKY FTr12B Receiver
Introduction
The FTr12B receiver adopts Flysky’s third-generation automatic frequency hopping digital system (AFHDS 3), which features dual antennas and bidirectional data transmission commonly known as telemetry plus an i-bus out/s.bus terminal and PWM/PPM switching at Channel 1 . Compatible with all AFHDS 3 transmitters and RF modules.

- Connect to battery positive pole
- Connect to battery negative pole
Tips：
- The added new NPA/B/C/D and BVD functions will be available with the release of a new firmware update in the end of 2020. The BVD harness [23] will not function until the new firmware has been installed.
- The 12] i-bus out/s.bus terminal will be replaced with the CH12 (NPA) function after the firmware upgrade.

Binding
-
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;
-
Put the transmitter into bind mode;
-
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. -
Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.
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.
Forced update
- 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.
- Go to the RX Setup menu on your transmitter and select “RX Update”.
- When the receiver LED flashes slowly, the update is successful.
Fail safe
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
The FTr12B receiver is compatible with all AFHDS 3 transmitters and RF modules (including PL18, NB4, NB4 Lite, FRM302 etc.)
Attention:
- 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 or loss of control.
- Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise.
- Keep the receiver’s antenna at least 1cm away from conductive materials such as carbon or metal.
- Do not power on the receiver during the setup process to prevent loss of control.
Certification
FCC Compliance Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
Warning: changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
EU DoC Declaration
Hereby, [Flysky Technology co., ltd] declares that the Radio Equipment
[FTr12B] is in compliance with RED 2014/53/EU.
The full text of the EU DoC is available at the following internet address:

RF Exposure Compliance
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator and your body. This transmitter
must not be co-located oroperating in conjunction with any other antenna or
transmitter.
Environmentally friendly disposal
Old electrical appliances must not be disposed of together with the residual
waste, but have to be disposed of separately. The disposal at the communal
collecting point via private persons is for free. The owner of old appliances
is responsible to bring the appliances to these collecting points or to
similar collection points. With this little personal effort, you contribute to
recycle valuable raw materials and the treatment of toxic substances.
