1.2 Important safety instructions
Read, follow, and retain for future reference all of the following
safety instructions. Heed all warnings on the unit and in the
operating instructions before operating the unit.
1. Cleaning - Unplug the unit from the outlet before cleaning.
Follow any instructions provided with the unit. Generally,
using a dry cloth for cleaning is sufficient but a moist, fluff-
free cloth or leather shammy may also be used. Do not use
liquid cleaners or aerosol cleaners.
2. Heat Sources - Do not install the unit near any heat
sources such as radiators, heaters, stoves, or other
equipment (including amplifiers) that produce heat.
3. Ventilation - Any openings in the unit enclosure are
provided for ventilation to prevent overheating and ensure
reliable operation. Do not block or cover these openings.
Do not place the unit in an enclosure unless proper
ventilation is provided, or the manufacturer's instructions
have been adhered to.
4. Object and liquid entry - Never push objects of any kind
into this unit through openings as they may touch
dangerous voltage points or short-out parts that could
result in a fire or electrical shock. Never spill liquid of any
kind on the unit. Do not place objects filled with liquids,
such as vases or cups, on the unit.
5. Lightning - For added protection during a lightning storm,
or when leaving this unit unattended and unused for long
periods, unplug the unit from the wall outlet and
disconnect the cable system. This will prevent damage to
the unit from lightning and power line surges.
6. Controls adjustment - Adjust only those controls specified
in the operating instructions. Improper adjustment of
other controls may cause damage to the unit. Use of
controls or adjustments, or performance of procedures
other than those specified, may result in hazardous
radiation exposure.
