7. For added protection for this product during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and dis-
connect the antenna or cable system. This will prevent
damage to the product due to lightning or power line
surges.8. Do not use attachments not recommended in this
owners manual as they may cause hazards.

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
