On cleaning
• To keep the cabinet looking new, periodically clean
it with a soft cloth. Stubborn stains may be removed
with a cloth lightly dampened with a mild detergent
solution. Never use strong solvents, such as thinner,
benzene, or abrasive cleansers, since these will
damage the cabinet.
• Avoid touching the lens. To remove dust on the lens,
use a soft dry cloth. Do not use a damp cloth,
detergent solution, or thinner.
• Clean the filter at regular intervals.
On repacking
• Save the original shipping carton and packing
material; they will come in handy if you ever have to
ship your unit. For maximum protection, repack your
unit as it was originally packed at the factory.
