LOT Number
The LOT number can be found on the bottom of the charging base adjacent to the [LOT] symbol.
The LOT number, for the handpiece, is also available on the display screen in Settings. In addition,
the LOT number is visible inside the housing of the handpiece, under the battery cover.
4.4 CALIBRATION
Loop
is the first curing light system with the ability to validate its delivery of irradiance to the tooth surface. To
™
maintain like new performance, it is recommended to perform a monthly calibration which is completed in a few
seconds.
The Loop
calibration and charging base is a calibration tool that will automatically verify that the unit has precise
™
power levels.
Initial and Monthly Calibration Steps:
1. Position the charging base on a flat stable surface and check that the green power indicator is on.
2. Check that the battery charge status icon on the handpiece OLED display screen is green.
3. Make sure there is not a protective barrier sleeve on the handpiece.
4. Check that the lens is properly cleaned and completely dry. If needed, clean the lens with the supplied Loop
lens cleaning cloth. Refer to Section 5 for "Maintenance and Cleaning".
5. Ensure that the handpiece tip is rotated so the alignment marks are matched (Refer to Section 4.6 "Positioning
the rotating tip").
6. Raise the charging base tip to the calibration position (Fig. 1).
7. Insert the handpiece into the charging base (Fig. 2). Verify that the lens is positioned securely within the white
calibration area.
8. Loop
will automatically perform a calibration. (Fig. 3) Upon successful completion, a green check mark (Fig.
™
4) will be displayed along with an audible beep. If a red X is displayed (Fig. 5), a failure has occurred, and you
should repeat step 1 to 8. Should the failure persist, please contact customer service.
9. After a successful calibration, remove the handpiece from the charging base and lower the charging base tip
to the normal position.
10. Loop
is ready for use or may remain in the charging base until needed.

There is no harm in calibrating the device more frequently than the recommended monthly time period. You may
calibrate more often for the following reasons:
• When a Self-Check Dirty Lens fails on repeated attempts. Refer to Section "4.5 Self-Check Dirty Lens Detection".
• After removing hardened dental material from the lens surface.
• When calibration was not conducted as scheduled.
