Selecting fine audio equipment such as the unit you’ve just
purchased is only the start of your musical enjoyment Now it’s time
to consider how you can maximize the fun and excitement your
equipment offers This manufacturer and the Electronic Industries
Association’s Consumer Electronics Group want you to get the most
out of your equipment by playing it at a safe level One that lets the
sound come through loud and clear without annoying blaring or
distortion-and, most importantly, without affecting your sensitive
hearing
We recommend you to avoid prolonged exposure to excessive
noise
Sound can be deceiving Over time your hearing “comfort level”
adapts to higher volumes of sound So what sounds “normal” can
actually be loud and harmful to your hearing
Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts
To establish a safe level
l Start your volume control at a low setting
l Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion
Once you have established a comfortable sound level
l Set the dial and leave it there
Taking a minute to do this now will help to prevent hearing
damage or loss in the future After all, we want you listening for a
lifetime

Polarization - If the unit is equipped with a polarized AC power
plug (a plug having one blade wider than the other), that plug
will fit into the AC outlet only one way This is a safety feature If
you are unable to insert the plug fully into the outlet, try
reversing the plug If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet Do not defeat the
safety purpose of the polarized plug
Power Cord Protection - AC power supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them Never take hold of the plug
or cord if your hand is wet, and always grasp the plug body
when connecting or disconnecting it
Nonuse Periods - When the unit is not used, turn the power
off When left unused for a long period of time, the unit should
be unplugged from the household AC outlet

with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode See figure below

The subwoofer can be placed in any position as long as it is at a
reasonable distance from the TV
Note that some experimentation can yield the smoothest low
frequency performance Placement near a corner can increase the
apparent output level, but can result in unnatural bass
