3-8. Power switch

[Out line]

The power switch has the positions ON and OFF (Stand-by) ON position: Usually the power switch needs to be set to t his posi-

tion when the POS-terminal is operated.

OFF position: This position is used to turn the stand-by mode. When

the power switch is set to this position, power supply stops automatically. But if the soft ware program control the power supply to hold, even if the power switch is set into this position, power supplying will be kept until an software program allows power supply no to hold.

[Operating method]

The power switch is a seesaw switch, and it can be tipped toward the ON or OFF.

4. Software

2. Cautions on handling CPU and POWER FAN

When removing or performing any other operation on the CPU and POWER FAN, be sure to handle them with care, because it may cause abnormal sound or deteriorate the performance while the CPU FAN is rotating if they are dropped or given heavy impact.

3. Note for handling of Touch panel

· The transparency of the touch panel should be vitally important.

Do not put finger prints or wat er print on the surface. Use clean finger such or gloves and masks.

· For handling, do not hold the transparent are, and do not hold the

heat seal connector section to assure reliability.

· Do not overlay touch panels. The edge may damage the surface.

· Do not put a heavy thing on the touch panel.

· Do not apply a strong shock, and do not drop it.

· When attaching the protection film again, carefully check for no

dirt. If there is any dirt, it is transferred.

· To clean dirt on the surface, use dry, soft cloth or a cloth immersed

in ethyl alcohol.

· Check that the housing does not give stress to the touch panel.

· Be careful not to touch the touch panel with tools.

· The heat seal section is easily disconnected. Be careful not to give

a stress to the heat seal section when installing.

· The touch panel is provided with an air groove to make the exter-

nal and the internal air pressure equal to each other. If water or oil is put around the air groove, it may penetrate inside. Be careful to keep the air groove away from water and oil.

· Input is performed with fingers. Do not use a hard thing for input-

ting.

4. Note for handling of LCD

· The LCD elements are made of glass. BE careful not to give them

strong mechanical shock, or they may be broken. Use extreme care not to break them.

· If the LCD element is broken and the liquid is leaked, do not lick it.

If the liquid is attached to your skin or cloth, immediately clean with soap.

· Use the unit under the rated conditions to prevent against damage.

· Be careful not to drop water or other liquid on the display surface.

· The reflection plate and the polarizing plate are easily scratched.

BE careful not to touch them with a hard thing such as glass, tweezers. Never hit, push, or rub the surface with hard things.

· When installing the unit, be careful not to apply stress to the LCD

module. If an excessive stress is applied, abnormal display or uneven color may result.
