Safety Precautions
Before getting started, please read the following important safety precautions.
1. Be sure to ground yourself to prevent static charge when installing the internal
components. Use a grounding wrist strap and place all electronic components in
any static-shielded devices. Most electronic components are sensitive to static
electrical charge.
2. Disconnect the power cord from the IRU152 before making any installation. Be
sure both the system and the external devices are turned OFF. Sudden surge of
power could ruin sensitive components. Make sure the IRU152 is properly
grounded.
3. Make sure the voltage of the power source is correct before connecting the
equipment to the power outlet.
4. Turn OFF the system power before cleaning. Clean the system using a cloth
only. Do not spray any liquid cleaner directly onto the screen.
5. Do not leave this equipment in an uncontrolled environment where the storage
temperature is below -45℃or above 85℃. It may damage the equipment.
6. Do not open the system’s back cover. If opening the cover for maintenance is a
must, only a trained technician is allowed to do so. Integrated circuits on
computer boards are sensitive to static electricity. To avoid damaging chips
from electrostatic discharge, observe the following precautions:
Before handling a board or integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. This will help to discharge any static
electricity on a human body.
When handling boards and components, wear a grounding wrist strap, available
from most electronic component stores.

General Cleaning Tips
You may need to take the following precautions before you begin to clean the
computer. When you clean any single part or component for the computer, please
read and understand the details below fully.
When you need to clean the device, please rub it with a piece of dry cloth.
1. Be cautious of the tiny removable components when you use a vacuum cleaner
to absorb the dirt on the floor.
2. Turn the system off before you start to clean up the component or computer.
3. Never drop the components inside the computer or get circuit board damp or
wet.
4. Be cautious of all kinds of cleaning solvents or chemicals when you use them
for the sake of cleaning. Some individuals may be allergic to the ingredients.
5. Try not to put any food, drink or cigarette around the computer.

Cleaning Tools
Although many companies have created products to help improve the process of
cleaning your computer and peripherals users can also use household items to clean
their computers and peripherals. Below is a listing of items you may need or want to
use while cleaning your computer or computer peripherals.
Keep in mind that some components in your computer may only be cleaned using a
product designed for cleaning the same types of components. Please read the
instructions that come with a cleaning product to avoid misusage.
Cloth: A piece of cloth is the best tool to use when rubbing up a component. Although
paper towels or tissues can be used on most hardware as well, we still recommend you
to rub it with a piece of cloth.
Water or rubbing alcohol: You may moisten a piece of cloth a bit with some
water or rubbing alcohol and rub it on the computer. Unknown solvents may be
harmful to the plastics parts.
Vacuum cleaner: Vacuuming the dust, dirt, hair, cigarette particles, and other
particles out of a computer can be one of the best methods of cleaning a
computer. Over time these items can restrict the airflow in a computer and
cause circuitry to corrode.
Cotton swabs: Cotton swaps moistened with rubbing alcohol or water are
excellent tools for wiping hard to reach areas in your keyboard, mouse, and
other locations.
Foam swabs: Whenever possible it is better to use lint free swabs such as foam
swabs.
Note
We strongly recommend that you should shut down the system before you start
to clean any components.
Please follow the steps below:
1. Close all application programs
2. Close operating software
3. Turn off power
4. Remove all devices
5. Pull out the power cable
