Color irregularity occurs on the TV screen.
The subwoofer and the front speakers in this system
are magnetically shielded to prevent magnetic
leakage. However, some leakage may occur, as a
high-strength magnet is employed. If this happens,
check the following items:
• If the speakers are used with a CRT-based TV or
projector, install the speakers at least 0.3 meters
(1.0 ft) from the TV set.
• If the color irregularity persists, turn off the TV set
once, then turn it on after 15 to 30 minutes.
• If howling occurs, reposition the speakers farther
away from the TV set.
• Make sure that no magnetic object (magnetic latch
on a TV stand, health care device, toy, etc.) is
placed near the speakers.
