Cautions - Hitachi CM2111M User Manual

The rear cover MUST be removed only by authorized service personnel. This colour monitor
contains high voltage components.
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.
After the power has been turned on or "DEGAUSS" button has been pressed, the CRT is
demagnetized for approximately 10 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 tapes/disks apart from this unit.
DO NOT repeat OFF and ON in a short period. It may cause blurred colours or distortion of the
displayed pattern.
For complete separation from the power source, remove the power cord from the monitor or
from the wall outlet.
Avoid direct rays of the sun or room lighting onto the CRT screen in order to prevent eye
fatigue.
This monitor has a non-glare and anti-electrostatic treatment on the surface of the screen.
Use water or an alcoholic solvent with a soft cloth like gauze to clean the surface of the screen.
NEVER use an abrasive, glass cleaner containing highly concentrated ammonia and strong base
chemicals since they damage the surface treatment.
Clean the cabinet and controls with a lightly moistened soft cloth.
DO NOT use aerosol sprays, solvents or abrasive cleaners.
