Be careful
of static electricity
on CRT surface!
To prevent electrical shock by the static electricity on the CRT surface, disconnect the
power cord at least 30 seconds after turning OFF the power.
~
Avoid frequent
power
ON-OFF
switching
!
Do not repeat OFF and ON power switching in a short period.
This may cause blurred
colours or distortion of the displayed pattern.
~
Be careful
of generated
magnetism
!
After the power has been turned ON or when the degauss function has been manually
engaged, the CRT is demagnetised for approximately 7 seconds.
This generates a
strong magnetic field around the front cover which may affect the data stored on
magnetic tape or disks near the front cover.
Place such magnetic recording equipment
and tapesldisks away from this unit.
