R3008SB CH MODE

The R3008SB receiver is a very versatile 

unit.  It has 8 PWM outputs, S.BUS and S.BUS2 

outputs.  Additionally the PWM outputs can be 

changed from channels 1-8 to channels 9-10.  If 

you only desire to use it as an 7 channel receiver 

(without S.BUS), it can be used without any 

setting changes.

* There is a danger of receiving an electric shock.

* A short circuit across the battery terminals may cause 

abnormal heating, fire and burns.

Please double check your polarity ( ＋ and 

－ ) when hooking up your connectors. 

* If ＋ and － of wiring are mistaken, it will damage, 

ignite and explode.

The R3008SB is capable of changing its channel 

allocations as described in the table below.   
1. Turn on the receiver.  (At this moment, the 

transmitter should be off.)  Then, LED blinks 

RED in about 3 seconds. Next, wait until it 

becomes solid RED.

2. Press and hold the Mode Switch more than 

5 seconds.

3. Release the button when the LED blinks 

RED and GREEN simultaneously.

4. The receiver is now in the "Operation 

CH Set" mode.  At this moment, the LED 

indicates current set status through flashing 

a pattern that corresponds to the CH 

mode.

*Cannot exit this CH setting mode before the operation 

mode is fixed.

*See the below table that shows correspondence between 

"CH mode" and way of flashing LED.

*Default CH mode is "Mode B".

5. By pressing the Mode Switch, the operation 

CH is switched sequentially as "Mode C"  

"Mode D"  "Mode A"....

6. The operation mode will be set by pressing 

the Mode Switch more than 2 seconds at 

the desired CH mode.

7. Release the button when the LED blinks 

RED and GREEN simultaneously. Then, the 

operation CH is fixed.

8. After confirming the operation CH mode 

is changed, turn off and back on the 

receiver power.

*The “Operation CH Set” mode cannot be changed during 

the receiver communicates to the transmitter.

Use this connector when using a voltage 

telemetry device to send the battery voltage (DC0 

~ 70V) from the receiver to the transmitter. 

You will need to purchase the optional External 

Voltage input cable (CA-RVIN-700) FUTM5551.

You can then make a cable with an extra 

connector to the External voltage connector.
