What This Guide Helps With
Error: WRONG USE displayed when a control button is held too long, causing table movement lockout or unresponsive controls.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- If the table is actively in use, stop all movement and ensure the patient is stable
- Transfer the patient if safe positioning cannot be maintained
Verify the Reported Error and Behavior
- Confirm “WRONG USE” is displayed on the control interface
- Observe when the error appears (during or after button press)
- Check if controls become unresponsive
Release All Control Buttons
- Ensure no buttons are being held down
- Release hand control and foot pedal inputs
- Wait a few seconds for system reset
Inspect Hand Control and Foot Pedal
- Check for stuck or continuously pressed buttons
- Inspect for debris, fluid intrusion, or physical damage
- Confirm buttons return to neutral position after pressing
Check Cable and Connection Integrity
- Verify hand control cable is fully seated
- Inspect for pinched, frayed, or damaged cables
- Ensure secure connections at all ports
Test Normal Operation
- Press one button at a time briefly
- Confirm smooth and responsive table movement
- Ensure error does not reappear
If the Problem Persists
If the error continues without any buttons being pressed, external causes have been ruled out. The issue may indicate a faulty hand control, foot pedal, or control interface circuit.
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device before performing any checks.
