To test and calibrate UV lamp radiation:

1. StartȱtheȱUVȱCalibrationȱWizardȱfromȱtheȱOptionsȱmenuȱ(seeȱfigure 6Ȭ22ȱ

onȱpage 6Ȭ23).

2. Inȱtheȱfollowingȱscreen,ȱselectȱ

Calibrate UV Intensity toȱadjustȱtheȱlamp’sȱ

radiationȱlevelȱtoȱtheȱacceptableȱrange.ȱ

Before testing and calibrating the UV lamps:

¾ Make sure the glass lens on each of the UV lamps is clean. For easy

access, run the Head Cleaning Wizard, and use the special cleaning pad

supplied.

¾ Make sure that the glass over the UV radiation sensor is clean.
