The NEC Versa 2205C has an internal modem that you can use to send and receive faxes, cruise the Internet, and download information. A modem converts data so it can be transmitted over phone lines and then converts it back again so you can read it on your computer.

Your NEC Versa 2205C comes with several online service gateways — all the basic software you need to communicate with the outside world.

Use the following procedure to connect a phone line to the NEC Versa 2205C.

NOTE

You also can use a PC card modem. This will necessitate disabling the internal modem. See the online

Basics

for how to disable the internal modem. See the online for information on how to purchase the modem PC card option.

Traveling with Your

NEC Versa 2205C

The NEC Versa 2205C makes a natural traveling companion. Using a battery, you can use the computer anywhere you go. Here is some information you might find helpful when taking the NEC Versa on the road.

■ Carry an extra charged battery pack for additional

battery power.

■ Check that you have everything you need before you leave

on a trip. Be sure you have all the necessary cables and accessories. (See the checklist at the end of this chapter.)

■ If you run your system with battery power, maximize

battery life by using power-saving features whenever possible.

■ Take the AC adapter in case you have an electrical

outlet handy. This saves battery power for when you really need it.

■ Carry along any application or data files on diskette that

you might need.

TIP: Speed the trip through airport security by carrying a charged system. Inspectors want to see the screen display a message. The boot message is usually sufficient.

If your system is fully charged, the inspection only takes a minute or so. Otherwise, be prepared to attach the AC adapter and power cable. If you don’t have these, the inspection might include a disassembly of the system.

POWER CONNECTIONS

With the right accessories, you can run your NEC Versa 2205C almost anywhere! Your system self-adjusts to various power sources. The United States, Canada, and most of Central and South America use 110-volt alternating current (AC). Most other countries of the world use 220-volt AC. The NEC Versa 2205C adapts to voltages ranging from 100 to 240 volts.

There are a few countries with areas that use direct current (DC) as their main power source. You need a DC-to-AC converter in particular areas of Argentina, Brazil, India, Madeira, and South Africa.

To use your system overseas, you need an adapter plug and transformer. There are five different plugs available worldwide. You can buy these at an electronics supply store.

TIP: When using a modem outside the U.S. and Canada, you might need an international telephone adapter. You can buy this at an electronics supply store.

For more information on using a modem, see Chapter 2, "Learning to Use the Hardware" and Appendix C, “Modem Commands, Registers, and Codes” in this guide.

Setting Up a Healthy

MAKING YOUR COMPUTER WORK FOR YOU

Work Environment

Prolonged or improper use of a computer workstation may pose a risk of serious injury. To reduce your risk of injury, set up and use your computer i n the manner described in this appendix.

Contact a doctor if you experience pain, tenderness, swelling, burning, cramping, stiffness, throbbing, weakness, soreness, tingling and/or numbness in the hands, wrists, arms, shoulders, neck, back, and/or legs.

Computers are everywhere. More and more people sit at computers for longer periods of time. This appendix explains how to set up your computer to fit your physical needs. This information is based on ergonomics — the science of making the workplace fit the needs of the worker.

WARNING

Some nerve, tendon, and muscle disorders (musculoskeletal disorders) may be associated with repetitive activities, im-

proper work environments, and incorrect work habits. Examples of musculoskeletal disorders that may be associated with certain forms of repetitive activities include: carpal tunnel syndrome, tendinitis, tenosynovitis, de Quervain’s tenosynovitis, and trigger finger, as well as other nerve, tendon, and muscle disorders.

Setting Up a Healthy Work Environment A-1

Page 66

Although some studies have shown an association between increasing hours of keyboard use and the development of some musculoskeletal disorders, it is still unclear whether working at a computer causes such disorders. Some doctors believe that using the keyboard and mouse may aggravate existing musculoskeletal disorders.

Some people are more susceptible to developing these disorders due to pre-existing conditions or psychosocial factors (see “Pre-existing Conditions and Psychosocial Factors” later in the appendix).

To reduce your risk of developing these disorders, follow the instructions in this appendix. If you experience discomfort while working at your computer or afterwards, even at night, contact a doctor as soon as possible. Signs of discomfort might include pain, tenderness, swelling, burning, cramping, stiffness, throbbing, weakness, soreness, tingling and/or numbness in the hands, wrists, arms, shoulders, neck, back, and/or legs.

NOTE

To increase your comfort and safety when using your notebook computer as your primary computer system at your home or office, note the following recommendations:

■ use a separate, external keyboard attached to

your notebook computer

■ use a separate, external monitor attached to

your notebook computer.

A-2 Setting Up a Healthy Work Environment

Page 67

ARRANGE YOUR EQUIPMENT

Arrange your equipment so that you can work in a natural and relaxed position. Place items that you use frequently within easy reach. Adjust your workstation setup to the proper height (as described in this appendix) by lowering the table or stand that holds your computer equipment or raising the seat height of your chair. Position your notebook computer directly in front of you for increased safety and comfort.

ADJUST YOUR CHAIR

Your chair should be adjustable and stable. Vary your posture throughout the day.

Check the following:

■ Keep your body in a relaxed yet upright position. The

backrest of your chair should support the inward curve of your back.

■ Use the entire seat and backrest to support your body.

Tilt the backrest slightly backwards. The angle formed by your thighs and back should be 90° or more.

■ Your seat depth should allow your lower back to com-

fortably contact the backrest. Make sure that the backs of your lower legs do not press against the front of the chair.

■ Extend your lower legs slightly so that the angle between

your thighs and lower legs is 90° or more.

■ Place your feet flat on the floor. Only use a footrest

when attempts to adjust your chair and workstation fail to keep your feet flat.

■ Be sure that you have adequate clearance between the

top of your thighs and the underside of your workstation.

Setting Up a Healthy Work Environment A-3

Page 68

■ Use armrests or forearm supports to support your fore-

arms. If adjustable, the armrests or forearm supports should initially be lowered while all the other adjustments discussed in this appendix are made. Once all these adjustments are completed, raise the armrests or adjust the forearm supports until they touch the forearms and allow the shoulder muscles to relax.

ADJUST YOUR INPUT DEVICES

Note the following points when positioning your notebook computer or any external input devices.

■ Position your keyboard directly in front of you. Avoid

reaching when using your keyboard or mouse.

■ If you use a mouse, position it at the same height as the

keyboard and next to the keyboard. Keep your wrists straight and use your entire arm when moving a mouse. Do not grasp the mouse tightly. Grasp the mouse lightly and loosely.

■ Adjust the keyboard height so that your elbows are near

your body and your forearms are parallel to the floor, with your forearms resting on either armrests or forearm supports, in the manner described previously. If you do not have armrests or forearm supports, your upper arms should hang comfortably at your sides.

■ Adjust the keyboard slope so that your wrists are

straight while you are typing.

■ Type with your hands and wrists floating above the key-

board. Use a wrist pad only to rest your wrists between typing. Avoid resting your wrists on sharp edges.

■ Type with your wrists straight. Instead of twisting your

wrists sideways to press hard-to-reach keys, move your whole arm. Keep from bending your wrists, hands, or fingers sideways.

A-4 Setting Up a Healthy Work Environment

Page 69

■ Press the keys gently; do not bang them. Keep your

shoulders, arms, hands, and fingers relaxed.

ADJUST YOUR SCREEN OR MONITOR

Correct placement and adjustment of the screen or external monitor can reduce eye, shoulder, and neck fatigue. Check the following when you position the screen or external monitor.

■ Adjust the height of your screen or external monitor so

that the top of the screen is at or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen or external monitor.

■ Position your screen or external monitor no closer than

12 inches and no further away than 28 inches from your eyes. The optimal distance is between 14 and 18 inches.

■ Rest your eyes periodically by focusing on an object at

least 20 feet away. Blink often.

■ Position the screen or external monitor at a 90° angle to

windows and other light sources to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen or external monitor.

■ If reflected light makes it hard for you to see your screen

or external monitor, use an anti-glare filter.

■ Clean your screen or external monitor regularly. Use a

lint-free, non-abrasive cloth and a non-alcohol, neutral, non-abrasive cleaning solution or glass cleaner to minimize dust.

■ Adjust the screen or external monitor’s brightness and

contrast controls to enhance readability.

■ Use a document holder placed close to the screen or ex-

ternal monitor.

Setting Up a Healthy Work Environment A-5

Page 70

■ Position whatever you are looking at most of the time

(the screen or reference material) directly in front of you to minimize turning your head while you are typing.

■ Get regular eye check-ups.

VARY YOUR WORKDAY

If you use your computer for prolonged periods, follow these instructions.

■ Vary your tasks throughout the day.

■ Take frequent short breaks that involve walking,

standing, and stretching. During these breaks, stretch muscles and joints that were in one position for an extended period of time. Relax muscles and joints that were active.

■ Use a timer or reminder software to remind you to

take breaks.

■ To enhance blood circulation, alter your sitting posture

periodically and keep your hands and wrists warm.

PRE-EXISTING CONDITIONS AND PSYCHOSOCIAL FACTORS

Pre-existing conditions that may cause or make some people more susceptible to musculoskeletal disorders include the following: hereditary factors, vascular disorders, obesity, nutritional deficiencies (e.g., Vitamin B deficiency), endocrine disorders (e.g., diabetes), hormonal imbalances, connective tissue disorders (e.g., arthritis), prior trauma (to the hands, wrists, arms, shoulders, neck, back, or legs), prior musculoskeletal disorders, aging, fluid retention due to pregnancy, poor physical conditioning and dietary habits, and other conditions.

Psychosocial factors associated with these disorders include: workplace stress, poor job satisfaction, lack of support by management, and/or lack of control over one’s work.

Modem Commands,

AT Commands

Registers, and Codes

AT commands, S registers, and result codes are universally understood instructions for network communications. Most fax/modem applications automatically initialize your modem with the proper AT commands and you do not need to change anything. In case you ever do need to communicate directly with your modem, or change a setup string, the following tables list the most commonly-used AT commands, S registers, and result codes that you can use to configure and use your optional internal 14.4 Kbps data/fax modem.

AT commands tell the modem how to operate. Except for the escape sequence (+++) (switch to command mode) and the commands in the following table with the letters

Entering a command without a value is the same as entering a command with zero (0) as the value. Bold indicates the default value.

A/ command (repeat last command), precede all the

AT.

S Registers

The modem provides S registers to let you control many of its parameters. Some of these S registers are Read-Only (RO) registers. Some are bit mapped. For bit-mapped S registers, each option controlled by the register is assigned a bit. The state of the bit determines whether the option is enabled. The value of the S register is then set by adding the values of all bits representing enabled options.

BATTERY DISPOSAL

Your bridge battery (not your main battery) is made of nickel-cadium (Nicad). the Nicad bridge battery must be collected, recycled, or disposed of in an environmentally-approved manner.

Your main battery, made of Lithium Ion (Li-Ion), and your CMOS lithium battery are not recyclable.

The incineration, landfilling, or mixing of Nicad batteries with the municipal solid wasted stream is prohibited by law in most areas.

Return Nicad batteries to a federal or state-approved recycler. This may be where you purchased the battery or a local seller of automotive bat-

teries. In MINNESOTA, call 1-800-225-PRBA if you need further disposal information.

Contact your local waste management officials for other information regarding the environmentally sound collection, recycling, and disposal of the batteries.
