WARNING
Do not perform the linking procedure while the motor's main wire connected
or the engine is operating as it may result in serious injury.
When the linking is complete, please cycle the receiver power and ensure
the receiver is properly linked to the transmitter.
Please power up your system in this order. Transmitter first, followed by the
receiver.
If the R7103SB receiver was previously linked to another transmitter, make
sure that transmitter is not operating while linking the receiver to the new
transmitter.
WARNING
Don't touch wiring.
* There is a danger of receiving an electric shock.
Don't connect to Extra Voltage before turning on a receiver.
When not using EXT-VOL, "EXT-VOL Mode" is turned OFF.
Don't connect EXT-VOL CABLE other than port 2 of R7103SB.
Link to the transmitter
Easy Link ID allows FASSTest 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
When the LED of the receiver changes from blinking red to solid green, linking
is complete.
* Refer to the transmitters operation manual for complete details on how to place the transmitter into the
linking mode.
* If there are many FASSTest 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 FASSTest
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 to double check whether your receiver is really under control 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.
＜ How to change R7103SB into "EXT-VOL Mode" ＞
1
Turn on the receiver. LED lights up red.
[Transmitter is always OFF]
2
Press and hold the Mode/Link button for 5 seconds to 10 seconds.
*It becomes the mode which makes a mistake in exceeding 10 seconds. In that case, carry out power

4
Each press of the Mode/Link button advances the receiver to the next mode.
5
When you reach the mode that you wish to operate in, press and hold the Mode/
Link button for more than 2 seconds.
6
When LED blinks in green with red, it is the completion of a mode change.
7

Measurement of Extra Voltag
R7103SB can display the voltage of a receiver battery on a transmitter.
Furthermore, the following procedures are required in order to display the voltage of
another battery (Drive battery etc.).
1
The optional adapter for CA-RVIN-700 is purchased.
2
R7103SB is changed into "EXT-VOL Mode" in the following procedure.
*If "EXT-VOL Mode" is used, the port 2 cannot be used as the servo CH.
3
According to the manual of CA-RVIN-700, battery wiring is branched and it
connects.
4
One side of EXT-VOL CABLE is connected to the port 2 of R7103SB.
Channel Modes
The R7103SB is capable of changing its channel allocations as described in the table
below. Please choose the mode which suited the use in the following procedure from the
11 modes.
1
Press and hold down the Link/Mode button on the R7103SB receiver.
[Transmitter is always OFF]
2
Turn the receiver on while holding down the Link/Mode button. After power up,
the button can be released.
3
The LED should now be blinking red with green.
4
Each press of the Mode/Link button advances the receiver to the next mode.
[Refer to CH Mode table shown below.]
5
When you reach the mode that you wish to operate in, press and hold the
Mode/Link button for more than 2 seconds.
6
When LED blinks in green with red, it is the completion of a mode change.
7
Please cycle the receiver power off and back on again after changing the
Channel Mode.
*5 seconds after the receiver ON, LED shows CH Mode.
