1M23N28504 Futaba. R304SB-E sBs2 T-FHSS-2.4GHz System S.BUS2, 4-Channel BIA Built-in Antenna Receiver Tao road for EP Car Models HIV AXWARNING
@ NEVER use dry batteries for the power supply of the R304SB-E as this may cause difficulties with the receiver's operation. NEVER use the R304SB-E in GP
(Engine) cars. Q@we 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 the place with good ventilation.
$e Thank you for purchasing the R304SB-E receiver. The R304SB-E is designed for use with the Futaba T-FHSS system transmitter. The R304SB-E receiver has adopted the newly developed bidirectional communication system "T-FHSS".
*Telemetry system With the telemetry system, the running status can be displayed at the transmitter. The telemetry data can be checked at the transmitter by connecting the telemetry sensor sold separately to the $.BUS2 connector of the R304SB-E receiver. 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. eBuilt-in antenna The R304SB-E receiver is designed to be used only for EP Car models. Note: The R304SB-E is compatible with the T-FHSS system transmitters. The receiver type setting of the transmitter is set T-FHSS.
*Futaba T-FHSS system does not work with current Futaba S-FHSS/FHSS/FASST-
est/FASST system. LED- Link switch CH output
(1 to 4) / (Battery) 2 + al] ~-s,BUS2 / (Battery) Operating Precautions:
Once the R304SB-E 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. 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. 1 Place the transmitter and the receiver close to each other within half (0.5) meter. 2 Place the transmitter into the linking mode, and turn on the receiver. 3 During countdown, push the receiver tact switch for approximately 2 seconds. The LED will begin to blink red. After the receiver LED switches from blinking red to green red steady light, If the transmitter and receiver are linked normally, set the power switch to the OFF position and then turn on the PWR ON position. If the receiver LED lights green, linking was succeeded. Actually check servo operation. AXWARNING

*Refer to the transmitters operation manual for complete details on how to place the transmitter into the linking mode.
*lf there are many T-FHSS systems turned on in close area, your receiver might have difficult in establishing a link to your transmitter. This is a rare occurrence. Your receiver may link to the undesirable 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. oO 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. Usage condition on High Speed mode A\caUTION
@ ren 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. 1 oo The Example of Connection CH2 ESC (Motor controller) fe ae i Temperature CH1 :@; Steering servo cnneor S.BUS2 (ii | RPM sensor Receiver Collect many telemetry HUB sensors by HUB and connect Voltage sensor them to $.BUS2 port.
