The sensor enclosure and DP-9000 exterior surfaces may be cleaned using a soft cloth and mild household cleaner. Do not use abrasive cleaners. Also brush the lenses, heat filters, and mirrors free of dust and lint from time to time with the lens brush supplied with the instrument. If any of these surfaces develops a hazy film, wipe it clean with a lens tissue or lintless cloth saturated with the anti-static lens cleaning solution, also supplied. Wipe the surface dry, but do not rub. Be particularly careful of the first-surface mirrors when cleaning.
Note: When illuminated by a bright light, the mirrors may appear to be slightly discolored and/or hazy. DO NOT attempt to remove this effect with cleaning. Slight surface imperfections will not affect instrument performance.
WARNING
To avoid electrical shock, make sure that the DP-9000 has been switched off and the power cord has been unplugged before cleaning. Do not allow water to get inside the enclosure.
