Antenna installation precaution
Do not cut or bundle the receiver antenna wire.
Do not bend the coaxial cable. It causes damage.
The antenna should not be pulled.
Keep the antenna as far away from the motor, ESC
and other noise sources as you possibly can.
Do not touch the antenna to metal, carbon, or other
conductive material.
Be sure that the two antennas are placed at 90 de-
grees to each other.
• The R3004SB has two antennas. In order to maximize signal reception and promote safe modeling Futaba has adopted a diversity antenna system. This allows the receiver to obtain RF signals on both
antennas and fly problem-free.
Antenna installation for carbon fuse
WARNING
The antenna portion of 30mm tip must be fully ex-
posed.
• Please make sure that the exposed portion won't slide back in the
fuse due to wind pressure or other force during the flight session.
Usage precaution
• Futaba T-FHSS Air system does not work with current Futaba
FASST/FASSTest/S-FHSS/T-FHSS Car system. Futaba FASST/
FASSTest/S-FHSS/T-FHSS Car system and T-FHSS Air system
are not compatible to each other.
WARNING
Wrap the receiver with something soft, such as foam
rubber, to avoid vibration. Moreover, the receiver must
not get wet.
Do not short-circuit the connectors.
Do not expose the receiver to high temperatures.
• The shrink cover could become distorted.
Do not break the tube.
• Could cause a short circuit.
When inserting and removing a connector, hold the
receiver tightly.
• Be careful so that a tube doesn't come off.

Thank you for purchasing a Futaba R3004SB T-FHSS Air-2.4GHz compatible receiver. The R3004SB receiver features bidirectional communication with a T-FHSS Air-2.4GHz Futaba transmitter using the S.BUS2 port. Using the S.BUS2 port an
impressive array of telemetry sensors may be utilized.
The receiver power
supply can be
connected to any port.

WARNING
Do not insert or remove the S.BUS2 connector while
the receiver power is ON.
Since the S.BUS2 servo switches the operation mode automatically
according to the type of signal (S.BUS2 signal/PWM signal) from the receiver, if the connector is inserted or removed while the power is ON, an
S.BUS2 connected servo will be erroneously recognized and may stop.
WARNING
Turn on the power on transmitter → receiver in order.
In addition, always check the operation of all the functions before flight.
e.g. Telemetry system
What is S.BUS2?
Different from conventional radio control systems, the
S.BUS2 system uses data communication to transmit control
signals from a receiver to a servo, gyro, or other S.BUS2
compatible devices. This data includes commands such as
“move the channel 3 servo to 15 degrees, move the channel 5
servo to 30 degrees” to multiple devices. The S.BUS2 devices
execute only those commands for their own set channel. For
this reason, it can be used by connecting multiple servos to
the same signal line. S.BUS devices can not be connected to
S.BUS2 port.

R3004SB Specications
T-FHSS Air 2.4GHz system/S.BUS2 port and 4 channels for
conventional system receiver
• Dual antenna diversity
• Size: 0.71 x 1.63 x 0.39 in. (18.0 x 41.4 x 9.9 mm)
• Weight: 0.17 oz. (4.8g)
• Power requirement: 4.8V to 7.4V
• Battery F/S Voltage: It sets up with a transmitter
• Frequency band: 2.4GHz band
• RF power output: 25mW EIRP
* Be sure that when using ESC's regulated output the current capac-
ity of the ESC meets your usage condition.
* S.BUS2 port: R3004SB can be used with up to 18 channels. How-
ever, it differs according to the transmitter. An unused channel is
a neutral signal. The F/S setting channel at F/S is F/S position
.
Another, it is Hold signal.
Link to the transmitter
Easy Link ID allows T-FHSS Air receivers to link to
compatible transmitter without pressing the link button on the
receiver.
1
Bring the transmitter and the receiver close
to each other, within 20 inches (half meter).
2
Turn on the transmitter. Place the transmitter into the receiver linking mode.
3
Turn on the receiver.
4
The receiver will wait for the linking process to begin for 5 seconds. Following that
it will return to the normal operation mode.
5
When the link is completed, the LED on
the receiver changes to solid.
* Refer to the transmitters operation manual for complete details on how
to place the transmitter into the linking mode.
WARNING
Do not perform the linking procedure while the mo-
tor's main wire connected or the engine is operating as it
may result in serious injury.
When the linking is complete, please cycle the receiver power and ensure the receiver is properly linked to the
transmitter.
Please power up your system in this order. Transmitter first, followed by the receiver.
If the R3004SB receiver was previously linked to another transmitter, make sure that transmitter is not operating while linking the receiver to the new transmitter.
* If there are many T-FHSS Air 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 Air
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 to double check whether your receiver is really under control by your transmitter.
* If the System Type of the transmitter is changed, the receiver will need
to be re-linked to the transmitter.
* Link is required when a new model is made from a model selection.
