Troubleshooting - Sony HT-M7 Operating Instructions Manual

On placement
• Place the receiver in a location with adequate
ventilation to prevent heat buildup and
prolong the life of the receiver.
• Do not place the receiver near heat sources,
or in a place subject to direct sunlight,
excessive dust, or mechanical shock.
• Do not place anything on top of the cabinet
that might block the ventilation holes and
cause malfunctions.
• Do not place the receiver near equipment
such as a TV, VCR, or tape deck. (If the
receiver is being used in combination with a
TV, VCR, or tape deck, and is placed too
close to that equipment, noise may result,
and picture quality may suffer. This is
especially likely when using an indoor
antenna (aerial). Therefore, we recommend
using an outdoor antenna (aerial).)
• Use caution when placing the receiver or
speakers on surfaces that have been specially
treated (with wax, oil, polish, etc.) as staining
or discoloration of the surface may result.
On operation
Before connecting other equipment, be sure to
turn off and unplug the receiver.
If you encounter color
irregularity on a nearby TV
screen
The center speaker is magnetically shielded to
allow it to be installed near a TV set. However,
color irregularities may still be observed on
certain types of TV sets. As the front speakers,
surround/surround back speakers and the
subwoofers are not magnetically shielded, we
recommend that you place them slightly
further away from a TV set (page 16).
If color irregularity is
observed...
Turn off the TV set, then turn it on again after
15 to 30 minutes.
If color irregularity is observed
again...
Place the speakers further away from the TV
set.
On cleaning
Clean the cabinet, panel, and controls with a
soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder, or solvent,
such as alcohol or benzine.
If you have any questions or problems
concerning your receiver, please consult your
nearest Sony dealer.
