354b
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed vehi-
cle, 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.

Maintenance
401b
• To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
