Trouble Correction
Power light is off and no screen display
is present when starting the machine.
1. Check power supply.
2. Check power cable and plug.
3. Check power adapter.
Character and gray scale are displayed,
but no ultrasonic image on the screen. Probe is not properly connected. Turn off the power and
reconnect the probe.
Intermittent stripe, snow, or far-field
interference appears on screen.
1. Check power supply.( spark interference present)
2. Check environment.(source of interference around the
machine, such as electric motor, ultrasonic atomizer,
automobile, computer or other interference )
3. Check power plug/socket of the instrument or probe
connectors. They shall be properly contacted.
Image display is not clear.
1. Adjust the total gain, near field, far field.
2. Adjust the brightness and contrast level.
Control panel malfunction Restart the system by turning off the main unit power.
9.3 Periodic Safety Checks
To ensure the system performance and safety, it must be checked after using 1 year. When check the
instrument, please consult the International Trade Dept of Kaixin or its dealers, as they need to have
professional technology engineers.
1. The following safety checks should be performed at least every 12 months by a qualified person who
has adequate training, knowledge, and practical experience to perform these tests.
 Inspect the equipment and accessories for mechanical and functional damage.
 Inspect the safety relevant labels for legibility.
 Inspect the fuse to verify compliance with rated current and breaking characteristics.
 Verify that the device functions properly as described in the instructions for use.
 Test the protection earth resistance according to IEC 60601-1: Limit: 0.1Ω.
 Test the earth leakage current according to IEC 60601-1: Limit: NC300μA, 300uA (for UL) SFC:
1000μA.
 Test the touch current according to IEC 60601-1: Limit: NC 100μA, SFC: 500μA.
 Test the patient leakage current according to IEC 60601-1: Limit: for a.c.: 100μA (B), for d.c.:
10μA (B).
 Test the patient leakage current under single fault condition with mains voltage on the applied part
according to IEC 60601-1: Limit: for a.c.: 500μA (B), for d.c.: 50μA (B).
The leakage current should never exceed the limit. The data should be recorded in an equipment log.
If the device is not functioning properly or fails any of the above tests, the device has to be repaired.
2. Please clean the plug of power cord at least once a year. Too much dust on plug may cause the fire.
