Installation:
9. Locate the equipment for proper ventilation. For ex-
ample, the equipment should not be placed on a bed,
sofa, rug, or similar surface that may block ventilation
openings; or, placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air
through the ventilation openings.
10. Locate the equipment away from heat sources such as
radiators, heat registers, stoves, or other appliance (in-
cluding amplifiers) that produce heat.
11. Mount the equipment in a wall or cabinet only as de-
scribed in this owners manual
12. Do not use this equipment near water; for example,
near a bathtub, washbowl, kitchen sink, laundry tub, in
a wet basement or near a swimming pool, etc.
13. Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The equipment may fall, caus-
ing serious injury to a person, and serious damage to
the product.
Connection:
