26 PRACTICAL FAULTSCheck probe connection, gain settings, freeze button, monitor cable, and power supply
Reconnect probe, inspect connector pins, try another port, and restart machine
Adjust gain, depth, focus, TGC settings, apply sufficient gel, and inspect probe surface
Increase gain, check power output, and verify probe contact with skin
Reduce gain, adjust TGC, and verify imaging preset
Press freeze/unfreeze button and verify system responsiveness
Clean probe, remove air bubbles in gel, and adjust scanning angle
Check probe cable for damage, reduce nearby electrical interference, and restart system
Verify depth control settings and selected imaging mode
Clean screen, restart system, and check touch calibration
Verify Doppler mode is enabled, adjust angle, and check velocity scale settings
Increase color gain, adjust ROI, and verify blood flow presence
Check charger connection, power outlet, and battery health
Allow system to cool, clean air vents, and ensure proper ventilation
Stop scanning temporarily, inspect probe, and check cooling recommendations
Close unnecessary functions, restart machine, and check storage availability
Verify power supply, battery condition, and system logs
Check calibration, imaging plane, and measurement settings
Check storage space, permissions, and connected storage devices
Reconnect USB device and verify compatibility
Check Wi-Fi/Ethernet settings and network availability
Verify printer connection, drivers, and paper availability
Reload presets, check user settings, and restore defaults if necessary
Record error code, restart system, and consult service documentation
Inspect cable for cuts, bends, or exposed wires and replace if needed
Perform system calibration according to manufacturer guidelines
