Precautions
"General
!Please ensure that the subwoofer/amplifier unit is positioned in a well-ventilated
area and that there is at least 10 cm (4") of free space along the sides and back.
There must also be a minimum of 15 cm (6") of free space on the top of the sub-
woofer/amplifier unit.
!Use the system on a firm, level surface free from vibration.
!Keep the system away from direct sunlight, strong magnetic fields, excessive dust,
humidity and electronic/electrical equipment (home computers, facsimiles, etc.)
which generate electrical noise.
!Do not place anything on top of the components.
!Do not expose the system to moisture, to temperatures higher than 60°C (140°F)
or to extremely low temperatures.
!If the system does not work properly, unplug and plug it in again. Then turn on the
system.
!In case of an electrical storm, unplug the subwoofer/amplifier unit for safety.
!Hold the AC power plug by the head when removing it from the wall socket, as
pulling the lead can damage internal wires.
!Do not remove the outer cover, as this may result in electric shock. Refer
internal service to your local SHARP service facility.
!The ventilation should not be impeded by covering the ventilation openings with
items, such as newspapers, tablecloths, curtains, etc.
!No naked flame sources, such as lighted candles, should be placed on the compo-
nents of the system.
!Attention should be drawn to the environmental aspects of battery disposal.
!This system should only be used within the range of 5°C - 35°C (41°F - 95°F).
Warning:
The voltage used must be the same as that specified by this system. Using this prod-
uct with a higher voltage other than that specified is dangerous and may result in a
fire or other types of accident, causing damage. SHARP will not be held responsible
for any damage resulting from the use of this system with a voltage other than that
specified.
Caution:
!The subwoofer/amplifier unit will get warm whilst being used. Do not touch warm
areas of the subwoofer/amplifier unit for prolonged periods to avoid damage to
you.
!This system is equipped with a special function which protects the amplifier circuit
from damage. When it is activated, the sound switch is turned off. In this case, set
the AV control unit to the stand-by mode and turn it on again.
"Volume control
The sound level at a given volume setting depends on speaker efficiency, location
and various other factors. It is advisable to avoid exposure to high volume levels,
which occur whilst turning the system on with the volume control setting up high, or
whilst continually listening at high volumes.
