Copyright 2014 Axiomtek Co., Ltd. All Rights Reserved Sep 2014, Version A1 Printed in Taiwan ii Safety Precautions Before getting started, please read the following important safety precautions. 1. User should not modify any unmentioned jumper setting without Axiomtek FAE’s instruction. Any modification without instruction might cause system to become damage 2. The tBOX323-835-FL does not come equipped with an operating system. An operating system must be loaded first before installing any software into the computer. 3. 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. 4. Disconnect the power cord from the tBOX323-835-FL 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 tBOX323-835-FL is properly grounded. 5. Make sure the voltage of the power source is correct before connecting the equipment to the power outlet. 6. Turn OFF the system power before cleaning. Clean the system using a cloth only. Do not spray any liquid cleaner directly onto the screen. 7. Do not leave this equipment in an uncontrolled environment where the storage temperature is below -40℃ or above 80℃. It may damage the equipment. 8. 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 your body. When handling boards and components, wear a wrist-grounding strap, available from most electronic component stores. iii Classification 1. 2. 3. 4. Degree of production against electric shock: not classified Degree of protection against the ingress of water: IP40 Equipment not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide. Mode of operation: Continuous General Cleaning Tips You may need 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 it 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. iv 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 able to be cleaned using a product designed for cleaning that component, if this is the case it will be mentioned in the cleaning. 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: Absorb 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 recommended that you should shut down the system before you start to clean any single components. Please follow the steps below: 1. Close all application programs 2. Close operating software 3. Turn off power switch 4. Remove all device 5. Pull out power cable v Scrap Computer Recycling If the computer equipments need the maintenance or are beyond repair, we strongly recommended that you should inform your Axiomtek distributor as soon as possible for the suitable solution. For the computers that are no longer useful or no longer working well, please contact your Axiomtek distributor for recycling and we will make the proper arrangement.
