Important Notes
Placement
354b
• Do not expose the unit to direct sunlight, place it near 
devices that radiate heat, leave it inside an enclosed 
vehicle, or otherwise subject it to temperature extremes. 
Also, do not allow lighting devices that normally are used 
while their light source is very close to the unit (such as a 
piano light), or powerful spotlights to shine upon the same 
area of the unit for extended periods of time. Excessive heat 
can deform or discolor the unit.
355
• To avoid possible breakdown, do not use the unit in a wet 
area, such as an area exposed to rain or other moisture.
356
• Do not allow rubber, vinyl, or similar materials to remain 
on the unit for long periods of time. Such objects can 
discolor or otherwise harmfully affect the finish.
357
• Do not put anything that contains water (e.g., flower vases) 
on the unit. Also, avoid the use of insecticides, perfumes, 
alcohol, nail polish, spray cans, etc., near the unit. Swiftly 
wipe away any liquid that spills on the unit using a dry, 
soft cloth.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth 
or one that has been slightly dampened with water. To 
remove stubborn dirt, use a cloth impregnated with a mild, 
non-abrasive detergent. Afterwards, be sure to wipe the 
unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any kind, 
to avoid the possibility of discoloration and/or defor-
mation.
Additional Precautions
558b
• To avoid disturbing your neighbors, try to keep the unit’s 
volume at reasonable levels (especially when it is late at 
night).
559a
• When you need to transport the unit, package it in the box 
(including padding) that it came in, if possible. Otherwise, 
you will need to use equivalent packaging materials.
