Compliance Information (for U.S.A.)

The Futaba R6203SB is a FASST-2.4GHz compatible receiver designed for remote control systems. It features an S.BUS system output port and three conventional system channel outputs, allowing it to be used with both S.BUS compatible servos and gyros, as well as conventional system servos.

Function Description:

The R6203SB receiver automatically recognizes the signal mode (FASST-2.4GHz 7ch mode or 8ch/10ch/Multi-ch mode) during the linking procedure. Users can also select between "high-speed mode" and "normal mode" for operation.

For conventional system output (Ch1-3) in "High Speed mode," it's crucial to note that this mode primarily accepts digital servos or most types of peripherals. Connecting analog servos to these outputs in high-speed mode can cause malfunction. Users are advised to check peripherals for any malfunction across the full stick lever throw and, if issues arise, to switch to "Normal mode."

The receiver supports FASST-2.4GHz 7ch or 8ch/10ch/Multi-ch systems.

Important Technical Specifications:

System Compatibility: FASST-2.4GHz (7ch/8ch/10ch/Multi-ch) system.
Outputs: S.BUS port and 3 channels for conventional system.
Antenna: Dual antenna diversity.
Size: 0.89 x 1.47 x 0.37 inches (22.5 x 37.4 x 9.3 mm).
Weight: 0.25 oz (7.2g).
Power Requirement: 3.7V to 7.4V (Voltage range: 3.5V to 8.4V).
- When using ESC's regulated output, ensure the ESC's capacity meets usage conditions.
- The Battery F/S (Fail Safe) voltage is set for 4-cell NiCd/NiMH batteries. The Battery F/S function may not work correctly with other battery types.
Fail Safe Function:
- In "Multi-ch" mode, fail-safe can be set for each channel, but this depends on the transmitter.
- In "7ch" mode, fail-safe can only be set for 3 channels.
S.BUS Port Capacity:
- In "7ch" mode, the R6203SB can handle up to 7 channels or less.
- In "8ch/10ch/Multi-ch" mode, it can handle 16 channels + DG1/2 or less, depending on the transmitter.

Usage Features:

Antenna Installation:

General: Ensure the two antennas are placed at a 90-degree angle to each other. Futaba's dual antenna diversity (DAD) seamlessly selects the best signal reception to prevent signal loss.
Carbon Fuse: The antenna portion, specifically the 30mm tip, must be fully exposed. Care should be taken to prevent the exposed portion from sliding back into the fuse due to wind pressure or other forces during flight.

Power Source Precautions:

Using a power source less than 4.0V is not recommended. If a lower voltage source is used, observe the following:
- The Fail Safe function MUST be "off" as battery fail-safe will interfere with normal operation.
- Before flight, ensure that the full loaded condition of the ESC and servos does not disrupt receiver operation. The receiver will stop operating if the supply voltage drops below 3.5V.
- Verify that the ESC or servos can maintain flawless operation even at lower voltages.
The power source voltage must not exceed the servo's rating.

Operation Mode Selection:

The receiver ships in "Normal mode." To change the mode:

Turn off the receiver.
Press and hold the Link/Mode switch, then turn on the receiver. Keep the switch held for more than one second. The LED will flash, indicating the current status.
Release the switch.
Turn off the receiver. This process toggles between "Normal" and "High Speed" modes.

LED Status during Mode Change:
- Holding the switch for 0 to 1 second: No function.
- Holding the switch for more than 1 second: Shows current mode with blinking LED (Red Blink = Normal, Green/Red Blink = High Speed). Then, the LED becomes solid as the mode changes (Red Solid = Normal, Green/Red Solid = High Speed, becoming Red after one second).
Checking Operation Mode:
- When turning on the receiver (without a FASST transmitter nearby for a firmer check):
  - LED is Red for "Normal mode."
  - LED is Green and Red (making Orange) for "High Speed mode" (changes to Red after two seconds).
- If a FASST transmitter is on nearby, the LED may briefly show the above status before changing to the status indicated in the "LED Indication" table.

Linking to the Transmitter:

Press and hold the Link/Mode switch for more than two seconds.
- WARNING: Do not perform the linking procedure with the motor's main wire connected or the engine operating, as this may result in serious injury.
- IMPORTANT: While linking, cycle receiver power and verify that the receiver is under the control of the intended transmitter.

Re-adjusting F/S Position (for TM-8 only):

Press and hold the Link/Mode switch between one and two seconds.

LED Indication Table:

Green Solid, Red Solid: Initializing when on "High Speed mode."
Green Off, Red Solid: No signal reception.
Green Solid, Red Off: Receiving signals.
Green Blink, Red Off: Receiving signals but ID is unmatched.
Alternate blink: Unrecoverable error (EEPROM, etc.).

What is S.BUS?

S.BUS is a data communication system that transmits control signals from a receiver to S.BUS compatible devices (servos, gyros, etc.). Instead of individual wires for each channel, S.BUS uses a single signal line to send commands like "move channel 3 servo to 15 degrees." S.BUS devices execute only commands for their own set channel, allowing multiple servos to be connected to the same signal line.

Connection by S.BUS system:

The R6203SB has an S.BUS output port. Conventional servos can also be used alongside S.BUS devices.

Channel settings for S.BUS servos can be configured using an SBC-1 channel changer or a CIU-2 USB serial interface.
Conventional servos cannot be used via the S.BUS output.
When using servos with a remote battery pack, use an S.BUS Hub with Cable (2-way/remote battery pack use). Refer to the instruction manual for the S.BUS Hub with Cable for connection methods.

Maintenance Features:

The device is designed for reliable operation with dual antenna diversity to ensure continuous signal reception.
The LED indicators provide clear status updates for linking, signal reception, and error conditions, aiding in troubleshooting.
The ability to switch between "Normal" and "High Speed" modes allows for flexibility in setup, but requires careful attention to servo compatibility to prevent malfunction.

Compliance Information (for U.S.A.):

The Futaba R6203SB complies with part 15 of the FCC Rules. Operation is subject to two conditions: (1) the device may not cause harmful interference, and (2) the device must accept any interference received, including interference that may cause undesired operation.
