6.3 Matters Common to Both LCD–Mounted Type
and Stand–Alone Type i Series
6.3.1 Liquid crystal display (LCD)
Brightness of the monochrome LCD
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.
LCD with a touch panel
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.
Protection sheet for the touch panel
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.)
Replacing the protection sheet
D Materials used
1)Protection sheet A02B–0236–K110 : For 10.4I LCD with touch
panel and soft key
A02B–0236–K130: For 10.4I 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)
D Replacement procedure
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.
• If the touch panel surface becomes cloudy, oil is still left on the
surface. Remove oil completely.
• 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.
<6> With a dry soft cloth, wipe off moisture completely.
