Do not put othe
r devices (a TV, a
display device, etc.) or magnetized
objects near the CRT monitor.
Installing the CRT monitor near those
may have an
effect on the screen
(disturbing colors or swaying the
screen).
★
Move the device seemed to effect
away as possible. In case the
phenomenon does not stop even so,
Ground the earth wire of the
