Verify Power and Connections
- Ensure the monitor is properly plugged into a working outlet.
- Confirm the AC adapter or battery is seated correctly and operational.
- Why: Touchscreen may appear unresponsive if the device is underpowered.
Check for Obstructions
- Clean the touchscreen with a soft, lint-free cloth and approved cleaner.
- Remove any screen protectors or films that may interfere.
- Why: Dirt, smudges, or residue can prevent proper touch recognition.
Restart the Monitor
- Power cycle the device: turn it off, wait 30 seconds, then turn it back on.
- Why: Temporary software or firmware glitches can cause touchscreen freezes.
Verify Input Method
- Ensure you are using a bare finger or approved stylus; other objects may not register.
- Why: The B450 touchscreen is capacitive and may not respond to non-approved objects.
Check Display and Calibration Settings
- Navigate (if possible via physical buttons) to touchscreen calibration settings and re-calibrate.
- Why: Miscalibration can make the touchscreen appear unresponsive or inaccurate.
Environmental Check
- Confirm the monitor is not exposed to excessive heat, moisture, or magnetic interference.
- Why: Environmental conditions can affect touchscreen sensitivity.
Test with External Interface (if available)
- If the monitor supports external input (mouse or keyboard), test responsiveness.
- Why: Determines if the issue is software-related or strictly touchscreen hardware.
If the Problem Persists
- Common external causes have been ruled out; the touchscreen or internal display controller may be failing.
- Action: Remove monitor from service. Label “Out of Service.” Send to Biomedical Engineering or vendor repair.
- Note: Knowing when to escalate is proper troubleshooting.
Clinical Use Tip
- Do not troubleshoot on an active patient. Move patient monitoring to a backup device before any troubleshooting.
- Only interact with the touchscreen when the monitor is safely offline.
Work Order Documentation (CCR Method)
Complaint
What was reported by the clinical staff.
Example:
“Touchscreen not responding during routine patient monitoring.”
Cause

Helpful Details to Include (If Known)
- Outlet tested and verified
- AC adapter or battery checked
- Screen cleaned and verified
- Monitor power-cycled
- Calibration attempted
- Environmental conditions noted
- Monitor removed from patient use
That is successful troubleshooting.
