Sony HT-SF470 Operating Instructions Manual page 66

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. Therefore, we recommend using an
outdoor antenna.
• 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 components, be sure
to tum 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 speakers and subwoofer are not
magnetically shielded, we recommend that
you place them slightly further away from TV
set (page 15).
If color irregularity is
observed...
Tum off the TV set, then tum it on again after
15 to 30 minutes.

On cleaning
• Clean the cabinet, panel, and controls with a
soft dry cloth. Do not use any type of
abrasive pad, scouring powder, scrubbing
brush or sponge.
• If it is stained with oil or fingerprints, breath
on the surface and wipe it with soft dry cloth.
On S-AIRfunction
• As the S-AIR product(s) transmits sound by
radio waves, sound may skip when radio
waves are obstructed. This is a characteristic
of radio waves and is not malfunction.
• As the S-AIR product(s) transmits sound by
radio waves, equipment that generates
electromagnetic energy, such as a
microwave oven, may interfere with sound
transmission.
• As the S-AIR product(s) uses the radio
waves that share the same frequency as other
wireless systems, such as wireless LAN or
Bluetooth devices, interference or poor
transmission may result. In this case, take
the following steps:
- Avoid placing the S-AIR product(s) near
other wireless systems.
- Avoid using the S-AIR product(s) and the
other wireless systems at the same time.
- The transmission may be improved by
changing the transmission channel
(frequency) of the other wireless
system(s). For details, refer to the
operating instructions of the other wireless
system(s).
