R334SBS

T-FHSS SR/T-FHSS-2.4GHz System
Diversity antenna
S.BUS2, 4-Channel Receiver for Model Car

Thank you for purchasing the
receiver. The

R334SBS

with the Futaba
transmitter. The

is designed for use

T-FHSS SR/T-FHSS

R334SBS

R334SBS

receiver has
adopted the newly developed high-speed
response system "

Note: The R334SBS is compatible with the
T-FHSS SR/T-FHSS system transmitters.
The receiver type setting of the transmitter is
set in T-FHSS SR/T-FHSS.

*Futaba T-FHSS system does not work with current

system

• SR servo

The servo corresponding to the SR mode is needed.
The servo type setting of the transmitter is set in SR mode.

• SR mode ON/OFF

ON/OFF of SR mode can be established according to each channel by
a transmitter setting. An OFF channel can use a normal servo/ESC.

• Telemetry function

Telemetry function cannot be used for the T-FHSS SR. Do not use the
S.BUS2 port in SR mode.

• Mode Change

To change the system mode, select the system mode (T-FHSS or

T-FHSS SR) of the transmitter rst.

Then, making a link between the transmitter and the receiver to build
up the radio linkage.

T-FHSS Re-Link T-FHSS SR

CAUTION

When using the T-FHSS SR mode, use an SR mode servo. Nomal servos
cannot be used.

• The use of nomal servos may cause servo trouble.

Usage condition on "T-FHSS 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.

WARNING

After the linking is done, please cycle receiver power and check if the receiver
to be linked is really under the control of 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.

• Telemetry system

With the
transmitter. By connecting
the

S.BUS2

the transmitter will be possible to show the telemetry data on its display.

• Normal mode/High Speed mode

The "Normal mode" accepts any type of servos or the peripheral. The
"High Speed mode" only accepts the digital servos, including BLS
series, and most peripheral equipments such as the brushless ESCs.
Please pay special attention to the information contained within this
manual and transmitter's manual in order to have a pleasant running
experience.
Operating Precautions (T-FHSS):
Once the R334SBS detects the T-FHSS normal mode or T-FHSS high
speed mode, the detected mode is locked as long as the power is ON.
When need to change the mode, please cycle power.

WARNING

NEVER remove the case to avoid the unexpected malfunction. When removing
a case from the double-stick tape, maintain the bottom case.

NEVER use dry batteries for the power supply of the R334SBS as this may
cause difficulties with the receiver's operation.

Wrap the receiver with something soft, such as foam rubber, to avoid vibration.
Do not splash water over the receiver.

Since the receiver generates a certain amount of heat, install in a place with
good ventilation.

Do not put any conductive equipment/sticker on the antenna part. (Receiver

• Otherwise, the operating range may become shorter.

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 within half a meter of each other.

1

Place the transmitter into the linking mode and turn on the receiver.

2

During countdown, push the receiver tact switch for approximately 2 seconds.

3

The LED will begin to blink red. After the receiver LED switches from blinking
red to green→green (red) steady light, If the transmitter and receiver are
linked normally, set the power switch to the OFF position and then return it to
the PWR ON position. If the receiver LED lights green, linking was successful.
(T4PLS,T4GRS : set the power switch to the OFF position and then return it to
the PWR ON position.) Actually check servo operation.

* Please refer to the table below for LED status and receiver condition.
* Refer to user manual of the transmitter, to change your transmitter in "Link" mode.
* If there are many T-FHSS systems turned on in close proximity, your receiver might have

difficulty establishing a link to your transmitter. This is a rare occurrence. However, should
another T-FHSS transmitter/receiver be linking at the same time, your receiver could link to the

wrong transmitter. This is very dangerous if you do not notice this situation. In order to avoid
the problem,we strongly recommend you double check whether your receiver is really under
control by your transmitter.
