9 Notice for Handling
A LCD (Liquid Crystal Display) has the following specific characteristics. These characteristics are not
indicative of a defect or malfunction.
(a) The display condition of an LCD may be affected by the ambient temperature.
(b) The LCD uses cold cathode tubes for backlight. Optical characteristics such as brightness or
uniformity will change during the LCD's life time
(c) Uneven brightness and/or small spots may appear depending on different display patterns.
(1) Electrostatic discharges may cause damage to a LCD. Therefore, the user should be handle a LCD with
care.
(2) The LCD display surface is made from a fragile glass material. Impulse or pressure to the LCD display
surface should be avoided.
(Shock < acceleration 30G X 7msec)
(3) The surface of the polarizer is very soft and easily scratched. Do not touch, push or rub by hard thing
more than HB of pencil hardness. (Even if using tissue paper, the surface of protection panel may be
scratched.) Also, please do not touch it by bare hand. Use a soft dry cloth for cleaning if there is dirt on
surface of panel. If dirt on surface is hard to remove, please wipe it with absorbent cotton, chamois or
other soft materials absorbing Normal-Hexane recommended as cleaning chemicals.
If using another type solution, there is a possibility that the surface of the panel may become discolored.
If a dirty cloth is used, there is a possibility that dirt from cloth may adhere to the surface of panel. Use
a clean cloth only. A pressure onto the surface of protection panel may cause the obstruction for
display)
(4) An atmosphere with high humidity should be avoided. If dew appears on the LCD monitor, the monitor
should be stored for over 30minutes in dry room prior to operating.
(5) Do not store and/or operate the LCD monitor in areas of high temperature and/or high humidity. Pack
the LCD monitor in electro-conductive pouch and store it under relatively low temperature atmosphere
(0 - 35 degree.C / 60%RH or below ), in case of a long term storage.
(6) Do not reassemble and/or readjust the LCD monitor.
(7) Do not display fixed pattern for an extended period of time may cause an after-image effect,
but it will disappear.
(8) Handle connector and cable with care.
(9) Light vertical stripes may be appeared depending on different display patterns. This is not trouble or
inferior.
(10) Light horizontal stripes may be appeared depending on different display patterns. This is not trouble or
inferior.
(11) Lamp start-up time also gets longer at lower temperature.
(12) Saliva and water drop on LCD display surface should be immediately wiped off since they degrade the
polarizer.
(13) Optical performance of the LCD changes by the temperature. (Response time gets longer at lower
temperature.)
(14) Please do not expose the LCD against the intensive light which is likely to degrade the polarizer & color
filter.
(15) If scratching by on the customer side, we don't bear the responsibility.
(16) The lamp of backlight has a little mercury. Please handle it appropriately in case of disposal.
