PLACING THE SPEAKERS

● Place the speakers on a sturdy vibration-free surface. If you

cannot obtain good bass quality when the speakers are placed

directly on the floor, insert a block etc. between the speakers

and the floor.

● Better stereo images will be obtained when the speakers are

slightly angled in towards the listeners.

Note

Bacause these speakers are not a magnetically shielded

type, there may be some influence on a TV picture

depending on the type of TV or the placement of the

speakers. In such a case, place the speakers apart from the

TV.

REMOVING THE FRONT COVER

The front cover is fixed to the cabinet at six points, and can be

removed if desired. To remove the cover, hold both sides and

slowly pull straight away from the speaker. To reattach, line up

the six pegs on the inside surface of the cover with the six

corresponding holes on the speaker and push gently.

Note

When the cover is removed, take care not to touch the

speaker units with your hands or to exert excessive force

with tools.
