DON’T continue to operate the equipment if you are in any doubt about it
working normally, or if it is damaged in any way—switch off, withdraw the mains
plug and consult your dealer.
DON’T remove any fixed cover as this may expose dangerous voltages.
DON’T leave equipment switched on when it is unattended unless it is specifically stated that it is
designed for unattended operation or has a standby mode.
Switch off using the switch on the equipment and make sure that your family know how to do this.
Special arrangements may need to be made for infirm of handicapped people.
DON’T use equipment such as personal stereos or radios so that you are distracted
from the requirements of traffic safety. It is illegal to watch television whilst driving.

damage your hearing.
DON’T obstruct the ventilation of the equipment, for example with curtains or soft furnishing.
Overheating will cause damage and shorten the life of the equipment.

complete safety always fit the manufacturer’s approved stand or legs with the
fixings provided according to the instructions.
DON’T allow electrical equipment to be exposed to rain or moisture.
ABOVE ALL.
NEVER let anyone, especially children, push anything into holes, slots or any
other opening in the case—this could result in a fatal electrical shock.
NEVER guess or take chances with electrical equipment of any kind—it is
better to be safe than sorry!

Precautions for installation
To prevent deformation or discoloration of the cabinet, do not install the unit
where it is exposed to direct sunlight or high humidity, and avoid installation near
air conditioning outlets.
Speaker vibrations may cause howling. Place the unit as far away from the player
as possible.
Take the occurrence of earthquakes or other physical shocks into consideration
when selecting the installation place, and secure the unit thoroughly.
Tuner reception may become noisy or hissing if this unit is installed nearby the
tuner. In this case, leave a more distance between the tuner and this unit or use
an outdoor antenna for better tuner reception without interference from this unit.
The unit is magnetically shielded to avoid color distortions on TVs. However,
if not installed properly, it may cause color distortions. So, pay attention to the
following when installing the unit.
When placing this unit near a TV set, turn off the TV’s main power switch or
unplug it before installing this unit.
Then wait at least 30 minutes before turning on the TV’s main power switch again.
Some TVs may still be affected even though you have followed the above. If this
happens, move this unit away from the TV.
When the TV screen shakes, move this unit away from the TV to find a position
where the screen doesn’t shake and then set the unit there.
