The RBRCTM Seal
The RBRCTM Seal on the easily removable nickel-cadmium battery pack contained
in our product indicates that SHARP is voluntarily participating in an industry program to
collect and recycle these battery packs at the end of their useful life, when taken out of
service within the United States. The RBRCTM program provides a convenient alternative to
placing spent nickel-cadmium battery packs into the trash or municipal waste stream,
which is illegal in some areas.
SHARP’s payments to RBRCTM makes it easy for you to drop off the spent battery pack at local retailers
of replacement nickel-cadmium batteries, or at authorized SHARP product service centers. You may also contact
your local recycling center for information on where to return the spent battery pack. SHARP’s involvement in this
program is part of its commitment to protecting our environment and conserving natural resources.

3-6. Shutdown switch
Shutdown switch used when the OS or application programs are
straying and the system can not return to the normal state.
You must not use this shutdown switch when the UP-5700 is running
normally. Use this switch only when the main power source is not cut
off even if the main unit power switch is set to OFF position. UP-5700
is turned OFF and the hardware is reset by turning the main power
switch OFF and then pressing the shutdown switch.
[Out line]
The shutdown switch is single shot type. (Normally OFF position)
Push ON: This position is used to reset stand-by mode for power
supply unit when software hang up.
Release OFF: Usually the shutdown switch needs to be set to this
position when the UP-5700 is operated.
[Operating method]
The shutdown switch is a push switch. If it is push ON, UP-5700
performs to stop supplying the power when the power switch is set
into stand-by mode.
NOTE: The shutdown operation will be ignore when te power switch
is set into power-on position.
3-7. System switch
The system switch is used to preset for system configuration.
[Out line]
The system switch is consist of DIP switch and Jumper switch.
[DIP switch]
The PSC2 simply reads switched signals from the DIP switch as
hardware. The meaning of DIP switch wholly depends on the soft-
ware.

3-8. Power switch
The power switch is used to turn the POS terminal on or stand-by
If the communication function is used, the AC power can be turned off
by software operation for power saving after communication.
[Out line]
The power switch has the positions ON and OFF (Stand-by)
ON position: Usually the power switch needs to be set to this 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 software program con-
trol 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.

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 water 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.
