User Manual

5. Range warning
Since the transmitter‟s output is much higher than that of the receiver, the user tends to be hard to notice
the seriousness of the situation and try to keep full control of the model. So when the receiver signal in
the down-link channel becomes too weak, the transmitter repeats a single warning beep every second.
You should fly back the model towards the safe place until the warning signal ceases. If the beep warning
does not cease when you fly back, it is that the transmitter or receiver low voltage warning or temperature
warning is activated, you must land the model and cease operations without delay in this situation.
RECEIVER
1. Servo connection
Plug the servos into the row of sockets on the right end of the receiver. The connector has polarity, note
the small chamfer on one edge. The socket polarity is also marked on the case, brown wire (-), red (+)
and orange (signal).The servo sockets of the receiver are numbered and one of the sockets, from
channel 1 to 6, can be used as the battery socket, and also both of the receiver power supply and the
servo can be connected to it in parallel with Y-lead. Especially the channel 6 that is used for the sum
signal could be programmed by the TELEMETRY BOX.
When using High Power servos, connect the receiver power supply to one of the sockets, from channel
1 to 6, with Y-lead

2. Telemetry socket
The channel 5 has “T” mark which means Telemetry interface. Telemetry interface with the optional
telemetry sensors, the latest firmware updating with the USB interface and the programming with the
SMART BOX could be processed. If the telemetry sensors are connected to the socket of the channel 5,
a servo is no longer work in this socket. When using receiver GR-12Li (JST ZHR-3 Conn) or GR-12Lm
(SHR-03V-S-B Conn), the adapter cable is also needed.
