Proper Care and Maintenance
Display
(1) Lightly wipe to clean the dirty surface with absorbent cotton or other soft material like chamois,
soaked in the recommended chemicals without scrubbing it hard. Always wipe the surface horizon-
tally or vertically. Never give a wipe in a circle. To prevent the display surface from damage and to
keep the appearance in good state, it is sufficient, in general, to wipe it with absorbent cotton.
(2) The Response time will be extremely delayed at the temperatures lower than the specified op-
erating temperature range. However, this phenomenon does not mean a defect of the LCD module.
It will disappear in the standard operating temperature range.
(3) If the display area is hardly pushed during an operation, some display patterns will be abnor-
mally displayed.
(4) Pointed position of touch panel may shift owing to a change in resistance of touch panel de-
pending on the operation condition. To compensate this shift, the set shall be given a calibration
function.
(5) Input shall be made with a stylus pen (supplied by WN, polyacetal-R0.8). Chances are very high
that use of a metal piece including a ballpoint pen or sharp edge will impair accuracy.
