In case color irregularity is observed

With the magnetically shielded type of speaker
system, the speakers can be installed near a TV set.
However, color irregularity may still be observed in
the TV screen depending on the type of your TV set.
If color irregularity is observed...
Turn off the TV set once, then turn it on after 15 to 30
minutes.
If color irregularity is observed
again...
Place the speakers farther away from the TV set.
