2. Remote control distance is not enough.
• The wrong position of transmitter antenna or receive antenna.
• Nearby radio interference.
• Battery is empty.
• Obstacle screens off part of the signal.
3. The transmitter can´t control the receiver.
• The transmitter or receiver enters into the bound status by

time.
• The distance between two transmitters is too close. Please keep
more than 5 meters as far as possible.
5. The item number of acquisition module does not appear in
the transmitter screen.
• The data cable of acquisition module is connected to the wrong
places.
• The plug of data cable is damaged.
6. The unstable data of speed acquisition.
• The position of speed sensor is not proper, which drifts too far.
7. The simulator can not be checked on the computer.
