Troubleshooting

Problems Caused by Faulty Hardware

NCD terminals have four major components: base, monitor, keyboard, and mouse. If found to be faulty, the base and/or monitor must be returned for repair. The mouse and/or keyboard are replaceable.

Isolating Faulty Components

One of the best ways of tracking down hardware problems is to swap components among compatible terminals. Swapping components lets you determine which component is faulty.

For example, if a keyboard appears to be faulty, turn off the terminal, disconnect the keyboard, and connect a keyboard from another NCD terminal. If the second keyboard works, you know that the problem is with the first keyboard and not with another component, such as the keyboard controller in the base.

Mouse Troubleshooting

Most mouse problems are caused by a dirty mouseball or a loose connection between the mouse cable and the base. If you have problems using your mouse:

1. Check the mouse cable connector. Make sure it is firmly connected to the base’s mouse connector.

2. Turn the mouse upside down and remove the ball. Clean the ball and its socket, and reassemble the mouse.

3. Clean your mouse pad or the area of the desk where your mouse sits.

Monitor Troubleshooting

Generally, if the monitor is out of focus, too bright, or too dark, adjust the monitor’s brightness and contrast knobs. Each monitor model has its own set of controls. Check the monitor operating booklet for more information about your monitor.

Base Troubleshooting

A flashing power indicator indicates there is a hardware problem in the base.

If you find you must return a base for repair, send it in the same configuration as when it failed.

In Case of Trouble

If you encounter difficulties, you can send e-mail or a FAX to NCD Technical Support or contact them by phone.

For information on services available from NCD Technical Support, contact your NCD representative or send mail to [email protected].

Returning Components

If you have to return a component, follow these steps.

1. Gather the information listed in “Phoning Technical Support.”

2. Contact NCD Service Operations to determine the faulty component and to obtain a Return Authorization Number (RMA).

• e-mail: [email protected]

• phone:(415) 691-7445

3. Once you have obtained an RMA number, package the component for return.

If possible, use the original cartons and packing materials. If the original cartons and materials are not available:

• Wrap each component in bubble wrap.

• Place each component in sturdy carton that leaves 4 inches of bubble

wrap and packing material around the component.

If you would rather not pack the component yourself, NCD recommends that you take it to a commercial packing and shipping company and ask that the content be wrapped according to these instructions.

4. Mark each return package with the assigned RMA number and address each package as shown below to avoid problems or delays:

Guidelines for Productive and Healthy Use of Your X Terminal

You may have rea d or heard of articles which have lin ked prolonged viewing of co mputer video display termin als with eye fatigue, and prolonged use of computer keyboards and mouse devices with repetitive stress injuries such as carpal tunnel syndrome. One common example is the syndrome known as “tennis elbow.” Although a conclusive direct causal relationship between computer use and these adverse health effects has yet to be scientifically proven, NCD recommends that you read and follow these guidelines in setting up and using your new NCD X terminal.

• Set up your X terminal in a well lit, glare and shadow-free environment.

• Avoid using your X terminal in a position you find awkward or unnatural.

• Select a chair that provides good lower back support. Adjust your chair so that your feet rest flat on the floor with your

thighs in a horizontal position.

• Place your keyboard on a surface so that your wrists are not tilted, or only slightly tilt ed while using the keyboard. Many people find a comfortable keyboard height is at the same level as their elbows.

• If the height of your work surface cannot be adjusted, position the chair at a comfortable height and use a footrest to place your feet on a level surface.

• Place your mouse on a surface which is at the same height as your keyboard. Many people find using the mouse and keyboard within 16" inches of the body is comfortable.

• Avoid resting your arm on your work surface and merely bending your wrist when using your mouse. Consider using a wristrest to provide a padded surface for your wrists when working with your mouse.

• Place y our display monitor at a comfortable viewing dista nce. Many pe ople fa vor a distan ce of 16" to 28" from their e yes. Position the screen so that you are not looking up or down at the screen.

• Take breaks to rest your eyes , stretch your muscles, and move around.

• Vary your work patterns so that you alternate working at your X terminal with other tasks that use different muscle groups

and allow you to focus yo ur eyes at different distances.

• See your physician if you experience persistent muscle ache, joint pain, eye fatigue or other discomfort when using your X terminal.

These are guidelines. What is comfortable for some may not be comfortable for you. You are the only one who can decide if these guidelines are appropriated for your needs.

What about electromagnetic emissi ons from your monitor? Many objects we encounter in our everyda y lives produce very low frequency (VLF) and extremely low frequency (ELF) electro-

magnetic emissions. These objects include such common appliances as portable cellular telephones, televisions, toasters, electric blankets, and video display terminals (VD T) such as the monitor wh ich is part of your X terminal. VDTs, have been the focus of a growing controversy over the potential health effect of VLF and ELF emissions.

NCD is monitoring this issue and shares the public’s concern over the potential health consequences of exposure to VLF and ELF emissions from VDTs. To date, the research and testing on this subject is i nconclusive. Moreover, the link, if any between VDT emissions a nd adverse health effects is unproven a nd the subject of much debate. Stress, postural stra in and poor working conditions are frequently cited in addition to, and instead o f, VDT emissions as posing p otential healt h hazards to frequent users of VDTs.

The prevailin g professional opin ion to date is that VDTs are safe. NCD products comply with the applicable regul ati ons and standards for electromagnetic radiation set forth by the U.S. Code of Federal Regulations, Underwriters Laboratories, Inc., the Canadian Stan dards A ssociation and the German VDE Standa rd. Whe n and if n ew or ad ditional stand ards are adopted, NCD w ill take appropriate steps to comply with them.

Even though the preponderance of profession al opinion i s that VDTs are sa fe, som e of our cust omers have asked us fo r informatio n on how to reduce th eir exposure to VLF and EL F emissions. Although NCD does not endorse the following as having health benefits, the easiest and perhaps most economical and effective measures are to turn off your display when not in use, to position your display at arm’s length, and to avoid working in areas where you are po sitioned close to the rear of a VDT where the emissions are strongest. Also, shields are available from third party vendors that reduce glare and electric emi ss ions.
