1-4. SAFETY PRECAUTIONS
The following messages are safety reminders on how to protect your systems from
damages, and extending the life cycle of the system.
1. Check the Line Voltage
a. The operating voltage for the power supply should be within the range of
100V to 240V AC; otherwise the system may be damaged.
2. Environmental Conditions
a. Place your PA-3122 on a sturdy, level surface. Be sure to allow enough
space around the system to have easy access needs.
b. Avoid installing your PA-3122 Series POS system in extremely hot or cold
places.
c. Avoid exposure to sunlight for a long period of time (for example, in a
closed car in summer time. Also avoid the system from any heating device.).
Or do not use the PA-3122 when it has been left outdoors in a cold winter
day.
d. Bear in mind that the operating ambient temperature is between 0°C and
35°C (32°F and 95°F).
e. Avoid moving the system rapidly from a hot place to a cold place, and vice
versa, because condensation may occur inside the system.
f. Protect your PA-3122 against strong vibrations, which may cause hard disk
failure.
g. Do not place the system too close to any radio-active device. Radio-active
device may cause signal interference.
h. Always shutdown the operation system before turning off the power.
3. Handling
a. Avoid placing heavy objects on the top of the system.
b. Do not turn the system upside down. This may cause the hard drive to
malfunction.
c. Do not allow any objects to fall into this product.
d. If water or other liquid spills into the product, unplug the power cord
immediately.

Chapter 1 Introduction
PA-3122 SERIES USER ′ S MANUAL Page: 1-7
4. Good Care
a. When the outside case gets stained, remove the stains using neutral washing
agent with a dry cloth.
b. Never use strong agents such as benzene and thinner to clean the surface of
the case.
c. If heavy stains are present, moisten a cloth with diluted neutral washing
agent or alcohol and then wipe thoroughly with a dry cloth.
d. If dust is accumulated on the case surface, remove it by using a special
vacuum cleaner for computers.

2-2-1. How to Set Jumpers
You can configure your board by setting the jumpers. A jumper consists of two or three
metal pins with a plastic base mounted on the card, and by using a small plastic "cap",
also known as the jumper cap (with a metal contact inside), you are able to connect the
pins. So you can set-up your hardware configuration by "opening"or "closing"pins.
Jumpers can be combined into sets that called jumper blocks. When jumpers are all in
the block, you have to put them together to set up the hardware configuration. The
figure below shows what this looks like.
Jumpers & caps
If a jumper has three pins for example, labelled PIN1, PIN2, and PIN3. You can
connect PIN1 & PIN2 to create one setting and shorting. You can either connect PIN2
& PIN3 to create another setting. The same jumper diagrams are applied all through
this manual. The figure below shows what the manual diagrams look and what they
represent.
