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.
