Switching the CarbonFX RF Receiver Mode
The built-in RF receiver can start in the wrong mode after factory delivery or a long period without use. Follow this sequence to switch it manually.
01 / BEFORE YOU START
When to use this guide
Use this procedure when a new CarbonFX, or one that has not been used for a long time, appears to have its built-in RF receiver in the wrong mode.
Disconnect the USB cable before you begin. The first button press must happen while CarbonFX is unpowered.
02 / MODE SWITCH
Follow the power-up sequence
The timing matters: hold Pairing first, then connect USB without releasing the button.
Hold the Pairing button
With CarbonFX still unpowered, press and keep holding the Pairing button.
Connect the USB cable
While continuing to hold Pairing, plug the USB cable into CarbonFX.
Check the white LED
Watch the white LED above the Pairing button on the left side and count how many times it flashes.
03 / LED CHECK
Confirm the receiver mode
The number of white LED flashes identifies the active receiver mode.
Wrong mode
Repeat the full sequence.
Correct mode
CarbonFX is now in the required RF receiver mode.
Wrong mode
Repeat the full sequence.
If you see one or three flashes, disconnect USB and repeat the steps above until the white LED flashes twice.
