Med X Change 4Klear Lite
Med X Change · Model 4Klear Lite
4Klear Lite is a Medical Grade Native 4K Camera designed for surgical microscopes. The remote camera head offers a large ½” Native 4K CMOS chip designed to better duplicate the surgeon’s field of view (FOV) seen in the microscope. Produce live 4K video, control camera settings and manage entire patient workflow via an easy to use 12.7cm multi-touch screen.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Image sensor / CCD fault
HighSymptoms: No image, color shift, or visible artifacts.
Root cause: Image sensor or its driver board aging.
Camera cable / connector wear
MediumSymptoms: Intermittent signal or no image at the tower.
Root cause: Cable flex fatigue or connector pin wear.
Coupler / lens fault
MediumSymptoms: Blurry, dark, or off-center image.
Root cause: Coupler or lens element misalignment/damage.
White balance / calibration fault
LowSymptoms: Color inaccuracy that won't correct on white-balance.
Root cause: Calibration drift or button/sensor fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Image sensor / CCD fault
- Confirm the presentation - typically no image, color shift, or visible artifacts.
- Check the most likely cause first: image sensor or its driver board aging.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the camera head / sensor assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Camera cable / connector wear
