What This Guide Helps With
Identifies common external causes of touchscreen or keyboard unresponsiveness, including power, cable connections, system freeze, calibration issues, or temporary software lockups.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Confirm no patient is actively undergoing an EKG.
Expected outcome: Safe environment for troubleshooting.
2. Verify Device Power
Check that the machine is fully powered on and battery (if applicable) is charged.
Expected outcome: Power indicators active; device ready for input.
3. Inspect External Connections
Ensure keyboard, touchscreen cable (if detachable), and USB connections are secure.
Expected outcome: No loose cables causing input failure.
4. Perform a Soft Reset
Power cycle the unit by turning it off, waiting 30 seconds, and turning it back on.
Expected outcome: Temporary software glitches cleared; touchscreen/keyboard responsive.
5. Check for System Freeze or Error Messages
Observe the display for frozen screens or error alerts.
Expected outcome: Device returns to normal operation or displays actionable error code.
6. Confirm Calibration (Touchscreen Only)
Access calibration menu if touchscreen partially responds; recalibrate per on-screen instructions.
Expected outcome: Touch input correctly recognized across screen.
7. Swap Input Device (If External Keyboard Present)
If using an external keyboard, test with a known good keyboard.
Expected outcome: Confirms whether failure is keyboard-specific.
If the Problem Persists
All external causes have been ruled out.
Device should be:
Removed from service
Labeled Out of Service
Sent for repair or bench evaluation
Knowing when to stop prevents patient risk and further device damage.
Clinical Use Tip
Never troubleshoot while a patient is on the table.
Move patient to another device before addressing input issues.
Ensure all data is saved before power cycling.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Touchscreen and keyboard not responding during routine EKG setup."
Cause
What was observed during troubleshooting.
Example:
"Power confirmed, cables secure, software may be frozen; input devices tested."
Resolution
What action was taken.
Example:
"Soft reset performed; device partially responsive; sent for service evaluation."
Helpful Details to Include (If Known)
- Power indicators
- Error messages observed
- Input device tested
- Calibration status
- Final device status (e.g., OOS)
Final Thought
Prioritize patient safety by halting procedures before troubleshooting. Start with logical external checks and escalate appropriately. Document all findings to maintain operational integrity and support repair workflow.
That is successful troubleshooting.
