6.7.8. Servicing Experience
The causes of troubles are simply analyzed only for reference because the circuit is complex, so
the troubles are not necessarily caused by following reasons. Our repair and maintenance are not
limited to follow the trouble analysis.
1. Trouble description: The indicator is still off and no display on the screen after the unit is
switched on.
Analysis: Maybe power supply or the power cord and plug is in trouble or the fuse breaks down,
or BRIGHT and CONTRAST need to be adjusted. If necessary, pull the fuse box out, replace
the old fuses, and then reposition the fuse box.
2. Trouble description: The signal of echo is abnormal.
Analysis: The probe may be broken, and then change it for another try. And if that doesn’t work,
the probe socket or mainboard may be broken down.
3. Trouble description: Interrupted Stripe and snow-shaped interference on the screen
Analysis: Maybe the power supply is interfered by other electrical equipment or operation
