For 8 mm to 18mm Amber Distance Gauges
To clean or replace the Distance Gauge window: (figure 6.1)
1. Wear dustless gloves to prevent smudges or fingerprints on lens.
2. Put the laser in STANDBY and remove the distance gauge assembly from the handpiece.
3. The Distance Gauge window is held in a groove in the rear (non treatment) end of the
assembly with an O-ring. A notched access in the groove allows easy removal of the O-
ring and window.
4. With the treatment end of the distance gauge pointing downwards, remove the O-ring with
tweezers, or poke a pointed object into the notch. Gently pull the O-ring toward the center
of the window to free the O-ring from the groove.
5. Turn the assembly upside down, allowing the window to fall out onto a clean surface. (If
needed, gently tap the side of the Distance Gauge with your finger).
6. (Used windows only)
a. Clean the windows in an alcohol solution. Rinse thoroughly with clean water, and dry
with a lint free tissue.
b. Re-inspect the window and if unacceptable, discard window and replace with a new
one.
7. Grasp the new or cleaned window by the edges and place it back into the Distance Gauge
assembly so it is resting flat on the ledge.
8. Reinsert the O-ring into the groove. Use the tip of the tweezers or a pointed object to
gently push the O-ring fully into the groove, being careful not to touch the window.
9. Perform a Calibration Procedure per section 5. Then slide the Distance Gauge back into
the HP.
