2.3

Installation Place

· The

monitor

should

placed away

from

the device which generates the

magnetic fields,

eg.

transformer and

motor,

because

the magnetic fields

cause

the miss-convergence.

• The sufficient ventilation

necessary

· In order

get the excellent display image and prevent eye fatigue,

recommended

avoid the

direct

light shining
