FCC ID: AZPR404SBS-24G Radio Control

1M23N38305 R404SBS-E F-4G-2.4GHz System Diversity antenna S.BUS2 Receiver for EP Car Models Thank you for purchasing the R404SBS-E receiver. The R404SBS-E is designed for use with the Futaba F-4G system transmitter. Note: The R404SBS-E is compatible with the F-4G system transmitters. The receiver type setting of the transmitter is set in F-4G.

*Futaba F-4G system does not work with current Futaba T-FHSS(SR)/S-FHSS/

FHSS/FASSTest/FASST/T-FHSS Air system. Usage conditions WARNING Be sure to use R404SBS-E under the following conditions. Use in EP (Electric motor) cars. NEVER use the R404SBS-E in GP (Engine) cars. Use with a 3.7 V to 7.4 V battery. NEVER use dry batteries. Transmitter RX type setting: F-4G Wrap the receiver with something soft, such as foam rubber, to avoid vibration. Do not splash water over the receiver. SR mode notes

* Use the SR servo for SR mode. Telemetry system With the telemetry system, the running status can be displayed at the transmitter. By connecting S.BUS sensors that are separately sold into the S (S.BUS2) port of the receiver (R404SBS-E), the transmitter will be possible to show the telemetry data on its display. Link notice WARNING Do not perform the linking procedure with motor's main wire connected as it may result in serious injury. 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. The settings will not be reflected unless restart. About the servos WARNING When the SR mode is ON, it is exclusively for SR compatible servos. Using a servo other than the SR compatible servo may cause malfunction of the servo or receiver.

* If a normal servo is connected to a CH with SR mode ON, there is a risk of damage.

* Do not connect the SR servo (set to SR mode) and the analog servo in the digital servo mode.

* Do not connect the SR servo (set to SR mode) in analog servo mode.

* Do not connect the SR servo (set to SR mode) in "S"-port (S.BUS2). Antenna attention WARNING Do not put any conductive equipment/sticker on the antenna part. Otherwise, the operating range may become shorter. The Example of Connection Antenna LED Indication Link Switch LED CH2 CH1 S No signal reception Receiving signals Unrecoverable fail-

ure (EEPROM,etc.) LED: Red LED: Green LED: Red and Green turn on alternately Motor controller Telemetry sensors

(Option) Steering servo CH5~CH10 servo S.BUS2 servo HUB Temperature sensor RPM sensor Voltage sensor Do not put decals or double-

sided tape on the antenna. Top Antenna Antenna R404SBS-E Do not install the receiver as shown on the left. 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 within half a meter of each other. 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 green 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.

* Please refer to the table for LED status and receiver condition.

* Refer to user manual of the transmitter, to change your transmitter in "Link" mode.

* If there are many F-4G 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 F-4G 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. Declaration of Conformity (for EU) Hereby, Futaba Corporation declares that the radio equipment type is R404SBS-E in compliance with Directive 2014/53/EU.
