5.9 Main unit check before and after operation
5.9.1 Inspection before start-up
Check the following items before starting the machine:
1. The temperature, humidity and atmospheric pressure shall meet the requirements of operation
condition.
2. No condensation occurs.
3. No distortion, damage or contamination on system and peripheral. Clean the parts as specified in
relevant sections, if the contaminant is present.
4. Check the control panel, LCD screen and enclosure to ensure they are in good working condition and
free of abnormity (such as cracks and loosened screws).
5. No damage on power cable, and hard up on its connection.
6. Check probe and its connections to ensure they are free of abnormity (such as scuffing, drop-off or
contamination). If the contaminant is present, clean, disinfect the contaminated objects as specified
in relevant sections.
7. No barriers around the intake of equipment.
8. See to it that probe has been cleaned, disinfected; else dispose it as specified in relevant sections.
9. Check all the ports of the machine for possible damage or blockage.
10. Clean the field and environment.
5.9.2 Inspection after start-up
Check the following items after starting the machine:
1. No abnormal voice, strange smell and overheating appear.
2. Check the machine to ensure a normal start-up: The power indication light is on and startup picture is
shown on the screen. Then the machine will be automatically set in B mode.
3. Check the acoustic lens for abnormal heat when the probe is in use. This can be done by hand
touching the probe to feel the temperature of the lens.
4. Check the image to ensure trouble-free display (no excessive noise or flicker).
5. Check the control panel to ensure normal operation condition.
6. Check the instrument to ensure that the phenomenon of local high temperature will not appear.
5.10 System reset
In case of abnormal screen display or no-working for system operation, try to restart the system by
turning on/off the main unit power.
Attention:
If the overheat acoustic lens is placed on the patient’s skin, heat injury may
occur.
Attention
: Thoroughly clean the coupling gel on the probe surface each time after
ultrasonic operation, or the coupling gel may become hardened on the acoustic lens of the
probe, deteriorating quality of image.
