Even if using a receiver with the BATTERY FAIL SAFE function, it may not operate correctly. Therefore always check the battery voltage and charge the battery quickly.
When using 5 or more servos for large scale models, use a separate power
supply. An S.BUS Hub with Cable (2-way/remote battery pack use) sold separately
can be utilized for using a separate power supply in the S.BUS system.
• System use
For full performance, 2.4GHz system is recommended.
• Programming function
This servo can be connected to a PC by using the CIU-2 USB Adapter sold
separately and its various operating characteristics can be changed as a programmable servo by means of dedicated software "S-Link". S-Link is downloadable from a Futaba WEB site. However, channel setting and other operating characteristics settings cannot be made with the existing S.BUS PCLink
software. When you use a transmitter with an S.BUS setting function. By connecting a servo to the S.BUS setting connector of the transmitter, a program
setup of a servo can be performed on the screen of a transmitter. This servo
does not have stop mode function. Therefore becomes as [ hold ] when the input
signal of a servo stops. Depending on a setup, a servo carries out vibration. If a
servo continues carrying out vibration, it will break, please restore a setup.

1. Set the channel at the S.BUS2 servos.
Set the channel at the S.BUS2 servos by using an S.BUS channel setting
tool.
* Refer to the S.BUS channel setting tool instruction manual for the S.BUS servo
channel setting method.
2. Connect the servos to an S.BUS or S.BUS2 compatible receiver.
Connect the servos from the S.BUS or S.BUS2 port of the S.BUS or S.BUS2
compatible receiver via S.BUS hubs.

:KDWLV6%86"
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 device. 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. Many S.BUS servos is
in the connected state, one servo of them can be set it up. The ID
code of each servo is used for it. ID code is indicated on the seal
of the case. After carrying in a model, it is convenient, if you use
attached ID seal and CH seal when ID cannot be seen.

High-Torque Servo Usage Precautions
zServo Horn
Please use an optional aluminum arm, when you use this servo with a large
scale model that is not less than 50cc. Attached resin arms will be damaged
because of the intensity shortage.
Also, please use the attached LOCK-SCREW. Ordinary screw will loose and
come off from the servo by the vibration.
