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.
Please pay special attention to the information

contained within this manual and transmitter's

manual in order to have a pleasant running/flying

WARNING

NEVER

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.

Place the transmitter and the receiver close

to each other within one (1) meter

Turn on the transmitter and the receiver.

Push and hold the Link switch on the

receiver.

When the link is complete, the LED on the

receiver changes to solid green.

* Please refer to the table below for LED status

and receiver condition.

No signal reception

Red : On

Receiving signals

Green: On

Receiving signals, but ID

is unmatched.

Green: Blink

* If there are many

S-FHSS/FHSS systems turned

on around your receiver, it might not link to your

transmitter. In this case, even if the receiver’s

LED stays solid green, unfor tunately the

receiver might have established a link to one of

the other transmitters. This is very dangerous

if you do not notice this situation. In order to

avoid the problem, we strongly recommend

you to double-check whether your receiver is

controlled by your transmitter by giving throttle

input, etc. and then checking servo response.

WARNING

After the linking is done, please

cycle receiver power and check if

the receiver to be linked is really under the

control by the transmitter to be linked.

Do not perform the linking procedure

with motor's main wire connected or

with the engine operating as it may result in

serious injury.

Operating Precautions:
Once the

R2104GF detects the S-FHSS

normal mode,

S-FHSS high speed

mode or

FHSS mode, the detected

mode is locked as long as the power

is ON. When need to change the

mode, please cycle power.

Note: Futaba

FHSS/S-FHSS system and FASST system are not compatible each other.

Usage condition on "High Speed mode"

CAUTION

When using the high-speed mode, use a

Futaba digital servo (including brushless

servo). Analog servos cannot be used.

• The use of analog servos may cause servo trouble.
