To prevent malfunctions caused by the weak batteries, charge the memory protection batteries for over 12-hours before installation or after a long-time vacation (over 30 days).

Before installation, initialize the terminal and leave it turn on over 12-hours.

•

After a long-time vacation, initialize the terminal and restore the program

•

data if the terminal is in malfunction, and leave it turn on over 12-hours. Over 48-hours charging makes the batteries fully charged.

3. DISASSEMBLY

NOTE:

* Please make a back-up copy of the clients’ data before disassembling.

* When the power is turned off, the internal battery enables the hibernate function.

* There are several kinds of screws. Be sure to use the

correct type of screws when reassembling.

It is advisable to sort the screws as shown in the right

after removing them.

* When assembling/disassembling the Stand, be careful not to get the ﬁngers caught.

* Use caution when handling the LCD unit and the inverter for the backlight as there is the risk of

high-voltage electrical shock.

* Internal battery:

• Do not disassemble or short-circuit the battery.

• Do not place the battery near a heat source or expose it to direct ﬂame or heat.

• Place the battery with its (+) and (-) terminals in the correct orientation.

• Do not recharge the battery. (Primary battery)

* When assembling, be sure that it is free of dust and other foreign matters. Pay special attention when replacing the touch panel and LCD

* Do not tangle the cables in principle.
