WARNING
This product is not a toy and is NOT suitable for children under the age of 14. Adults should keep the product out of the reach of children and exercise caution when operating this product in the presence of children.

1. R8SM Introduction
RadioLink R8SM is a 2.4G 8 channels receiver with weight of 1.5g(0.05oz) and dimension of 18x13mm(0.71”x0.51”), supporting signal output of PPM and SBUS and is compatible with RadioLink transmitter T8FB/T8S.
2. Binding
Each receiver has an individual ID code and must bind with transmitter before using. When the binding is done, the ID code will be stored in the transmitter and there’s no need to rebind. Therefore, when a new R8SM is purchased, binding needs to be done in order to work with transmitter.
Binding steps
Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.
Switch on the transmitter and the RED led on R8SM will start flashing slowly.
There is a black binding button(ID SET) on the side of receiver. Press the button for more than 1 second and release, the RED led will flash quickly, meaning binding process is ongoing.
When the RED led stops flashing and is always on, binding is complete. If not succeed, repeat the above steps.
3. Working Modes
Two signal working modes
Blue/purple LED, S-BUS signal, 8 channels totally.
Red LED, PPM signal, 8 channels totally
S-BUS and PPM signal change
Quick press the ID SET switch twice within 1 second, the signal is changed from S-BUS to PPM.
The red LED indicates the PPM and blue/purple indicates S-BUS.

5. Note of Antenna Installation
In order to maximize the signal transmission, it’s greatly advised that
Keep antennas as straight as possible, or the effective control range will reduce.
Big models may contain metal parts that influence signal emission. In this case. antennas should be positioned at both sides of the model to ensure the best signal status in all circumstances.
Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no over bending.
Keep antennas away from motor, ESC or other possible interference sources.
Sponge or foam material is advised to use to prevent vibration when installing receiver.
Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration and high temperature.
Special vibration-proof material for R/C like foam or rubber cloth is used to pack to protect receiver. Keeping the receiver in a well sealed plastic bag can avoid humidity and dust, which would possibly make the receiver out of control.
When all the above steps are complete, please turn off the transmitter and repower on to test if the receiver is correctly bind with it.
Thank you again for choosing RadioLink product.
