SERVICING NOTES
If the TV picture or monitor display is
magnetically distorted
Although this system is magnetically shielded, there
may be cases that the picture on some TV sets/personal
computer sets may become magnetically distorted. In
such a case, turn off the power of the TV set/personal
computer set once, and after 15 to 30 minutes turn it on
again. For the personal computer set, take the
appropriate measures such as data storage before
turning it off.
When there seems to be no improvement, locate the
system further away from the TV set/personal
computer set. Furthermore, be sure not to place objects
in which magnets are attached or used near the TV set/
personal computer set, such as audio racks, TV stands,
toys etc. These may cause magnetic distortion to the
picture due to their interaction with the system.
