When the ambient temperature is low, the brightness of the LCD
decreases. (The LCD screen is dark particularly immediately after the
power is turned on.) This phenomenon is not a failure but is a property
specific to the LCD. When the ambient temperature increases, the LCD
screen becomes brighter. The monochrome LCD has a brightness control
function. For the method of adjustment, see Section 1.17.
The touch panel is operated by directly touching the LCD screen. For this
operation, be sure to use a FANUC–supplied pen (A02B–0236–K111)
dedicated to the touch panel. If a sharp–pointed pen is used, for example,
to touch the LCD screen, the LCD surface may be flawed or damaged.
Moreover, do not touch the LCD screen directly with a finger. Otherwise,
the operability of the LCD may deteriorate, and the LCD screen may get
dirty.
A protection sheet is attached the face of an LCD with a touch panel to
protect the thin film of the touch panel and LCD. If the protection sheet
is damaged, it can be replaced. (The protection sheet is a consumable
part.)
1) Protection sheet A02B–0236–K110:For 10.4” LCD with touch
panel and soft key
A02B–0236–K130:For 10.4” LCD with touch
panel
2) Neutral detergent (detergent that can clean oily dirt off = detergent
for kitchen can be used)
3) Soft cloth (such as towel)
1) Before replacement
<1> Turn off the power to the machine.
<2> Peel off the old protection sheet from the surface of the touch
panel.
<3> Wipe off adhesive residue if any on the screen surface with
alcohol.
<4> Use the detergent to remove oil or dirt stuck to the surface of the
touch panel.
<5> With a soft, damp cloth, wipe off detergent completely.
D If the touch panel surface becomes cloudy, oil is still left on
the surface. Remove oil completely.
D If oil or detergent is left on the surface of the touch panel, the
protection sheet cannot adhere to the panel completely and
will sometimes peel off easily.
