Device calibration ensures accurate treatment delivery and maintains safety standards.
When Calibration is Needed (For CLINICAL DEVICES, used for multiple patients, Home Devices used by one patient can acknowledge the CAL message)
Regular Calibration Schedule:
- Every 100 hours of use, OR
- Once per year (whichever occurs first)
- When lamps are replaced
- If your device displays a "CAL Needed" message (this message will appear 100 hours after calibration or when one year passes since calibration)
Signs Your Device Needs Calibration:
- "CAL Needed" message
- Longer treatment times than normal
- Changes in treatment effectiveness
- After any lamp replacement
CAL Needed Resolution
When You See "CAL Needed":
- Do not continue treatments until calibration is completed
