Precautions - Sony HT-DDW1500 Operating Instructions Manual

Precautions

On safety
Should any solid object or liquid fall into the
cabinet, unplug the receiver and have it
checked by qualified personnel before
operating it any further.
On power sources
• Before operating the receiver, check that the
operating voltage is identical with your local
power supply.
The operating voltage is indicated on the
nameplate on the back of the receiver.
• The unit is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the unit
itself has been turned off.
• If you are not going to use the receiver for a
long time, be sure to disconnect the receiver
from the wall outlet. To disconnect the AC
power cord, grasp the plug itself; never pull
the cord.
• The AC power cord must be changed only at
a qualified service shop.
On heat buildup
Although the receiver heats up during
operation, this is not a malfunction. If you
continuously use this receiver at a large
volume, the cabinet temperature of the top,
side and bottom rises considerably. To avoid
burning yourself, do not touch the cabinet.
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 television, VCR, or tape deck. (If
the receiver is being used in combination
with a television, 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 turn off and unplug the receiver.
If you encounter color
irregularity on a nearby TV
screen
The front and center speakers and the sub
woofers are 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 surround and
surround back speakers 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 once, then turn it on again
after 15 to 30 minutes.
If color irregularity is observed
again...
Place the speaker further away from the TV
set.
If howling occurs
Reposition the speakers or turn down the
volume on the receiver.
