LABELS
Each IS4220 has a serial number label and a laser class label on the bottom of
the unit. These labels provide important information like; date and location of
manufacture, model number, serial number, caution statements and laser class.
There is also text molded into the top of the case near the window that says,
“AVOID EXPOSURE - laser light emitted from this aperture”. The following
Figure shows examples of these labels*.
