What This Guide Helps With
Use when adjustable system components, monitor positioning, or other operator-positioning features cannot be moved or secured normally.
Step-by-Step Troubleshooting
1. Protect the Patient and Prevent Unintended Movement
Stop using any positioning feature that binds, drops, drifts, releases unexpectedly, or cannot be safely secured. Move the patient or examination to another verified system if the positioning problem interferes with safe scanning.
Expected outcome: The patient is not exposed to unstable equipment or unintended movement.
2. Confirm Which Motion Is Actually Affected
Identify the exact component staff cannot position. The Resona I9 is an ultrasound system and does not use the imaging gantry or powered patient table arrangement found on CT or radiographic systems, so document the actual affected system component rather than assuming a gantry fault.
Expected outcome: The affected monitor, console, cart, support, or other positioning component is clearly identified.
3. Inspect for Physical Obstruction
Check around the affected component for cables, probe cords, accessories, storage items, wall contact, furniture, or other objects restricting normal movement. Do not force a mechanism through resistance.
Expected outcome: The normal travel path is unobstructed. If clearing an obstruction restores smooth and secure positioning, troubleshooting can stop after verification.
4. Check Locks, Brakes, and User-Accessible Releases
Verify accessible positioning locks, cart brakes, latches, or release controls are in the correct state for the requested movement. Inspect for obvious damage or incomplete engagement without disassembling the mechanism.
Expected outcome: User-accessible locking and release mechanisms operate normally and the component can be positioned safely.
5. Inspect External Cables During Movement
Check that probe cables, power cords, network cables, peripheral cables, and other external connections have adequate slack and are not caught around moving structures.
Expected outcome: External cabling does not restrict motion or become pinched during positioning.
6. Compare Normal Mechanical Feel
With the system unloaded and safe to manipulate, move the affected component only through its normal intended range. Stop immediately if there is grinding, excessive resistance, looseness, instability, or inability to hold position.
Expected outcome: Movement is smooth, controlled, and stable. If normal movement and secure positioning are restored, proceed to final verification.
7. Check for Recent Movement or Impact
Determine whether the system was recently transported, struck, repositioned between rooms, or had accessories added. Inspect externally for bent supports, loose covers, damaged handles, or other visible evidence.
Expected outcome: No transport-related or externally visible mechanical condition remains.
8. Perform Final Functional Verification
Verify the affected component can be moved through the required clinical positions, remains where placed, does not pinch cables, and does not interfere with probe use or operator access.
Expected outcome: Positioning is smooth, secure, and repeatable. If successful, troubleshooting can stop and the system may be returned to service according to facility policy.
If the Problem Persists
External obstruction, locks, cables, accessories, and obvious mechanical causes have been ruled out. Persistent inability to move or securely position a component may involve a mechanical support, adjustment mechanism, brake, structural component, or other service-level condition.
Remove the device from service if the positioning problem creates instability, pinch risk, uncontrolled movement, or interferes with safe clinical operation. Label it Out of Service and send it for repair or bench evaluation using appropriate Mindray documentation and approved test equipment.
Mechanical adjustment or repair should be performed only by qualified personnel. After repair, verify the full required range of movement, stability, cable clearance, and basic system function before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Never force an ultrasound monitor, console, or support mechanism that binds; unexpected release can injure the patient or operator and damage connected cables.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported the Resona I9 monitor assembly could not be positioned normally during examinations."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an external peripheral cable routed through the movement path and restricting travel."
Resolution
What action was taken.
Example:
"Clinical Engineering rerouted and secured the cable, verified smooth positioning and stable operation throughout the required range, and returned the system to service."
Helpful Details to Include (If Known)
- Exact component affected
- Whether movement is blocked, stiff, loose, or drifting
- Position where the problem occurs
- Lock or brake condition
- Cable routing
- Recent transport or impact
- Visible physical damage
- Abnormal noise during movement
- Results before and after correction
- Final device status
Final Thought
Protect the patient from unstable equipment, identify the actual affected motion, rule out external obstruction and cable problems first, verify safe positioning, escalate mechanical faults appropriately, and document the findings clearly.
That is successful troubleshooting.
