- Mount the bound receiver in the target place in the model.
- Switch on the RC system so that you could observe the movement of the servos.
- Put the model on a at 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 ying 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 specic transmitter and follow the procedures of your
specic 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 specic transmitter. the status LED on the
receiver turns solid green when terminated.
- Have your helper position the model and check effective radio range before every
ight while simulate all the servo movements which will take place when the model is
in ght. The ground range must always be at least 50m in order to ensure safe and
reliable model control.
The last bound receiver is the master receiver when the system would be in use. Every
telemetry sensors installed in the model must be connected to the master receiver,
since the only master receiver transmits sensor data through the downlink channel. The
second and all further receivers are operated as the slave mode which are connected
in parallel to the master, with the downlink channel switched off. The control signals can
be passed to a number of receivers simultaneously and also the different signal can be
assigned to each receiver through the Channel Mapping function of the transmitter or
the optional SMART BOX. The typical example would be the use of two servos for each
aileron, etc.
NOTICE : Make sure to double check that transmitter is bound to receiver by turning
off/on transmitter’s power after binging process is completed
2) Range checking
Before every ying session and especially with a new model, it is important to perform a
range check. All Graupner aircraft transmitters incorporate a range testing system which,
when activated, reduces the output power, allowing a range check. Notice that every
ying must not be permitted in the range checking mode and the model is restrained on
the ground. After binding the receiver to the transmitter, switch the on transmitter and
the receiver and wait until the status LED on the receiver turns solid red.
