LED will keep flashing slowly to notify, repeat the above steps.
Note: The close distance between the transmitter and receiver may cause a signal block, which
leads to unsuccessful binding or signal loss. After the binding is successful, if RC8X and R8FG
receiver are too close (for example, within 60 centimeters), the signal may also be lost because
of signal block. Bring RC8X transmitter and R8FG receiver farther apart, the signal loss will
disappear automatically.

Receiver Setting

Receiver Selection (Protocol Selection):

If the receiver you are using is not the standard R8FG, but other
versions R8FG or other receivers such as R7FG, R6FG, etc., please
select "FHSS V1" or "FHSS V2" in the "Basic Menu" - "Receiver
setting" of RC8X (as shown on the right), and then bind them. FHSS
V1 receivers have a PWM output resolution of 2048, and FHSS V2
receivers have a PWM output resolution of 4096. The higher the
resolution, the more delicate the angle of servo motion.
Please click "Receivers List" (as shown above) to check whether the receiver you are currently
using belongs to this list. If yes, please click the box on the right to confirm the current receiver
type. If not, please do not select this list. If the receiver list selected here does not include the
receiver model you are actually using, the binding may not be successful. For example: If you
want to use R7FG with RC8X, you need to select FHSS V1 and then bind them. If FHSS V2 is
selected, binding will not be successful.

Servo Speed Setting:

1. Transmitter: It is necessary to update the RC8X firmware to V1.1.5 or above, and then select
FHSS V2 protocol to display this option. Servo speed can be selected from 14ms, 4ms, and 3ms.
The default servo speed is 14ms (analog servo speed), 4ms and 3ms (digital servo speed).
2. Receiver: If you are using a digital servo, you need to choose a servo speed of 4ms or 3ms.
Please confirm whether the receiver you are using supports digital servo. Currently, RadioLink
receivers that support digital servo include R8FG V2.1, R4FGM V2.1, and R8FG and R4FGM
receivers with a factory date of 2023/4/26 and later. Other versions of RadioLink receivers do not
support digital servo. Even if 4ms or 3ms is selected when using them, the default servo speed is
14ms. RadioLink will continue to add other models of receivers that support digital servos in the
future. Please pay attention to RadioLink official website.
3. Status indication: When switching the servo speed, the green LED light of the receiver will
flash twice, which means that the switching of the servo speed is successful; if the green LED of
the receiver does not flash when switching the servo speed of the servo, it means that the
switching of the servo speed of the servo is unsuccessful or the current receiver does not
support digital servos.
Attention:
1. RC8X comes with R8FG receiver. R8FG V1.0 (production date before Feb. 6, 2023) only
supports FHSS V1 protocol, not FHSS V2 protocol; R8FG V2.0 and later versions (production
date on or after Feb. 6, 2023) support FHSS V2 protocol. Mini receiver R4FGM V1.0 supports
FHSS V1 protocol, and R4FGM V2.0 and later versions support FHSS V2 protocol. Before
