1.

To assure the finest performance, please read this manual
carefully.  Keep it in a safe place for future reference.

2.

Install this unit in a cool, dry, clean place – away from windows,
heat sources, sources of excessive vibration, dust, moisture and
cold.  Avoid sources of humming (transformers, motors).  To
prevent fire or electrical shock, do not expose the unit to rain or
water.

3.

Never open the cabinet.  If something drops into the set, contact
your dealer.

4.

Do not use force on switches, controls or connection wires.  When
moving the unit, first disconnect the power plug and the wires
connected to other equipment. Never pull the wire itself.

5.

Do not attempt to clean the unit with chemical solvents; this might
damage the finish.  Use a clean, dry cloth.

6.

Be sure to read the “TROUBLESHOOTING” section regarding
common operating errors before concluding that the unit is faulty.

7.

When not planning to use this unit for long periods of time (ie.,
vacation, etc.), disconnect the AC power plug from the wall outlet.

8.

To prevent lightning damage, disconnect the AC power plug when
there is an electrical storm.

9.

Since this unit has a built-in power amplifier, heat will radiate from
the rear panel.  Therefore, place the unit apart from the walls,
allowing a space of at least 10 cm (3-15/16”) above, behind and
on the both sides of the unit. Also, do not position with the rear
panel facing down on the floor or other surface.

10.

Super-bass frequencies reproduced by this unit may cause a
turntable to generate a howling sound. In such a case, move this
unit away from the turntable.

11.

As this speaker contains strong magnet, avoid placing watches,
magnetic tapes, etc. near this unit. Also, placing the speaker near
a TV set may impair picture color. If this happens, move the TV
set away from the speaker.

12.

If you hear distortion (i.e., unnatural, intermittent “rapping” or
“hammering” sounds) coming from this unit, reduce the volume
level. Extremely loud playing of a movie soundtrack’s low
frequency, bass-heavy sounds or similarly loud popular music
passages can damage this speaker system.

13.

This unit has a port called “air woofer” which is for reproducing a
super-bass sound.
Be careful not to put a hand or some objects into the port,
otherwise it may give you an electric shock or give this unit a
damage, or cause a fire.

IMPORTANT
Please record the serial number of this unit in the space below.

Serial No.:

The serial number is located on the rear of the unit.
Retain this Owner’s Manual in a safe place for future reference.
