General troubleshooting:
Standing Wave Alarm
1.The antenna is not connected
2. Feeders rolled together, did not start;
3. Antenna installation from the ground, wall or metal objects too close, adjust the antenna
installation location;
4. Antenna oscillator height and frequency do not match, adjust the height of the antenna to
the launch point.
Temperature alarm
1.Fan does not turn
2. The antenna does not match,which causes standing wave too large and temperature rises.
Adjust the antenna oscillator height corresponding to the launch frequency or adjust the
antenna position;
3. Into the outlet there are obstacles, blocked the flow of air temperature is too high;
4. engine room air convection, or the engine room temperature is too high.
