Link Procedure
Each transmitter has an individually assigned,
unique ID code. In order to start operation, the
receiver must be linked with the ID code of the
transmitter with which it is being paired. Once the
link is made, the ID code is stored in the receiver
and no further linking is necessary unless the
receiver is to be used with another transmitter.

Built-in antenna
4-channel receiver
Thank you for purchasing the
R204GF-E
receiver.
The
R204GF-E
is designed for use with the Futaba
S-FHSS
or
FHSS
system transmitter. The
S-FHSS
system has two(2) operation mode as shown below.
•Normal mode/High Speed mode
The "Normal mode" accepts any type of servos or the
peripherals as the frame rate of the output is 13.6ms.
The "High Speed mode" only accepts the digital
servos, including BLS series, and most peripheral
equipments such as the brushless ESCs. The frame rate
of the outputs is 6.8ms. However, there is a transmitter
that cannot correspond, to high speed mode.
Please pay special attention to the information
contained within this manual and transmitter's manual
in order to have a pleasant running experience.
•Built-in antenna
The
R204GF-E
receiver is designed to be used only
for EP Car models. Due to the special design of the
R204GF-E
, we cannot recommend its use in other
types of models (gas poweredmodels.)
•The R204GF-E is compatible with the
S-FHSS or FHSS system transmitters.
