Sony HT-IV300 Operating Instructions Manual page 10

Precautions
Use the unit near the wall outlet.
Disconnect the power plug from the
wall outlet immediately to cut off the
power supply completely if the unit
should emit smoke or an unusual smell
or should while using the unit.
Turning off the power button on the
unit does not cut off the power supply
completely.
On starting and shutting
down the unit
It takes some time until the unit starts/
shuts down after pressing the power
button since the unit optimizes the whole
system. Do not disconnect the power
plug from the wall outlet while the unit is
being turned off. Doing so could result in
malfunction.
Note on residual image
phenomenon
Do not leave a still image of the unit such
as the menu screen displayed on a TV
screen for long hours. This could result
in residual image phenomenon.
On placement
Do not install the unit in the following
places:
• Anywhere there is much vibration
• Anywhere that is extremely humid or
under direct sunlight
• Anywhere that is extremely cold or hot
Also, do not place any object filled with
water such as a flower vase on the unit or
use the unit where water may splash. If
water splash on the unit, a malfunction
may occur.

When moving the unit
Before connecting/wiring work, turn off
the unit. Make sure the unit is off, and
then disconnect the power plug from the
wall outlet.
On moisture condensation
Condensation creates a phenomenon
where moisture in the air adheres to
surfaces such as metal panels, etc., and
then changes to liquid. Note that
condensation may form temporarily in
cases such as when the unit is moved
quickly from a low-temperature
environment to a high temperature
environment or used in a room that has a
heater just turned on.
If condensation forms in the unit, leave it
turned off until the condensation
disappears.
• When the power plug is not connected
to the wall outlet, do not connect the
power plug and leave the unit.
• When the power of the unit is off, do
not turn on the unit and leave it.
• When the power of the unit is on, leave
it with the power on.
If you use the unit with condensation
present, a malfunction could result.
Cleaning the unit
Clean the cabinet and panel with a soft
cloth slightly moistened with a mild
detergent solution. Do not use thinner,
benzine, or alcohol which will damage
the surface.
When starting playback
Before starting playback, lower the
volume of the unit. If the volume is high
from the beginning, unexpected loud
sound may be output and it could
damage the speakers.
