2. Channel Mapping
Access Receive CH mapping on transmitter then you may change to the desired channel
3. Range check
Before every flying session and especially with a new model, it is important to perform a range check. All
SJ aircraft transmitters incorporate a range testing system which, when activated, reduces the output
power, allowing a range check. Notice that every flying must not be permitted in the range checking
mode and the model is restrained on the ground. After binding the receiver to the transmitter, turn on
transmitter‟s power first and then turn on receiver‟s power. Make sure that the system is operating
normally through servo movement.
• Mount the bound receiver in the target place in the model.
• Turn on the RC system so that you could observe the movement of the servos.
• Put the model on a flat surface (pavement, closely mown grass or earth), and ensure that the receiver
antenna should be at least 15cm above from the ground.
• Face the model with the transmitter in your normal flying position, the antenna on the transmitter
shouldn‟t be toward the model directly and it keeps stand horizontally during range checking
• Enter range check mode of your specific transmitter and follow the procedures of your specific
transmitter to check the range. the transmitter repeat a single beep with a regular rhythm, indicating
the Range checking is processed normally.
• Walk over 50 meters away from the model with controlling the transmitter sticks constantly and check
whether the model is operating normally. You should have total control of the model with the trainer
switch pulled
• If control issues exist within 50 meters, the system should not be used. And contact your local Service
Department of SJ INCORPERATED.
• Range-check is automatically terminated in 90 seconds and it is also terminated by turning off the
range check function of your specific transmitter. the red status LED on receiver turns off when
terminated.
• Have your helper position the model and check effective radio range before every flight while simulate
all the servo movements which will take place when the model is in fight. The ground range must
always be at least 50m in order to ensure safe and reliable model control.
CAUTION: During normal operations (i. e. when controlling a model) never enter the
range check mode !
4. Fail-Safe function
In its default state, the receiver is set to “Hold” mode. If you lose connection, all channels hold last
given command and the status LED on the receiver turn solid red. The transmitter also repeats a single
warning beep every second. You can use the fail safe option by programming the throttle channel to
respond to a fail-safe situation. : the throttle channel of an engine-powered model should be set to idle,
the throttle channel of an electric-powered model to “stop”, and the throttle channel of a model
helicopter to “Hold”. When a signal is lost the throttle channel, all channels are driven to the failsafe
position so that it could prevent the model crashing and the personal injury or property damage.
