WARNING
Do not insert or remove the S.BUS connector while
the receiver power is ON.
Since the S.BUS servo switches the operation mode automatically
according to the type of signal (S.BUS signal/PWM signal) from the re-
ceiver, if the connector is inserted or removed while the power is ON, an
S.BUS 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 func-
tions before flight.
What is S.BUS?
Different from conventional radio control systems, the
S.BUS
system uses data communication to transmit control signals
from a receiver to a servo, gyro, or other
S.BUS
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.BUS
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.
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 3 seconds. Following that it will return to the
normal operation mode.
5
When the LED of the receiver changes from blinking
red to solid green, linking is completed.
(A link waiting state is ended in 3 second.)
* 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 receiv-
er power and ensure the receiver is properly linked to the
transmitter.
Please power up your system in this order. Transmit-
ter first, followed by the receiver.
If the R3001SB receiver was previously linked to an-
other transmitter, make sure that transmitter is not oper-
ating 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 transmit-
ter. 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 no-
tice this situation. In order to avoid the problem,we strongly recom-
mend you to double check whether your receiver is really under con-
trol 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.
Channel Modes (S.BUS
⇔
CH3)
The R3001SB 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 sta-
tus through flashing a pattern that corresponds to the
CH mode.
*Cannot exit this CH setting mode before the operation mode is
fixed.
**See the next 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 B" "Mode A" "Mode
B"....
Mode A
Mode B

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.
