About the Modem

This equipment complies with Part 68 of FCC rules. On the bottom of this equipment is a label that contains, among other information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this information must be provided to the telephone company.

The modem jack of this equipment complies with Sub-part F of Part 68 of FCC rules.

The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total RENs contact the telephone company to determine the maximum REN for the calling areas.

If the terminal equipment causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. But if advance notice isn't practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it necessary.

The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications in order to maintain uninterrupted service.

If trouble is experienced with this equipment, please contact Sharp Electronics Corp. for repair and (or) warranty information (Refer to the end of this section). If the trouble is causing harm to the telephone network, the telephone company may request you remove the equipment from the network until the problem is resolved.

The equipment cannot be used on public coin service provided by the telephone company. Connection to Party Line Service is subject to state tariffs. (Contact the state public utility commission, public service commission or corporation commission for information.)

ii

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device, including fax machines, to send any message unless such message clearly contains in a margin at the top or bottom of each transmitted page or on the first page of the transmission, the date and time it is sent and an identification of the business or other entity, or other individual sending the message and the telephone number of the sending machine or such business, other entity, or individual. (The telephone number provided may not be a 900 number or any other number for which charges exceed local or long-distance transmission charges.) To program this information, refer to the manual of the communication software.

Notice for Users in Canada

About the Modem

The Industry Canada label identifies certified equipment.

This certification means that the equipment meet certain telecommunications network protective, operational and safety requirements. The department does not guarantee the equipment will operate to the user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company.

The equipment must also be installed using an acceptable method of connection. In some cases, the company's inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

CAUTION Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

“The Ringer Equivalence Number (REN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device. To prevent overloading, the termination on a loop may consist of any combination of devices subject only to the requirement that the total of Ringer Equivalence Number of all the devices does not exceed 5.”

CHAPTER 1

1

Fast Start

Your new computer is ready to use as soon as you unpack it from the box. If you’re familiar with computers, follow the instructions in this chapter to get your system up and running in just a few minutes. If this is your first computer, you should read through the entire Operation Manual before starting the system.

Connecting AC Power

Run your computer the first time using AC power, rather than battery power. This ensures that you will not lose power while you complete the Windows setup operation.

Use only the AC adapter that was supplied with your computer,

or supplied by your computer vendor. You can damage your computer if you try to use an AC adapter that is not approved for use with this system.

When removing the AC power cord from a wall outlet, grip the plug and pull it from the socket. Never remove the power cord from the outlet by pulling on the cord. Always grip the plug.

Place your computer on a flat working surface and follow the steps below.

1.On the front edge of the computer, slide the cover latch to the right and raise the cover.

Cover latch

1-1

2.Plug the cable from the AC adapter into the AC adapter jack on the left side of the computer.

3.Connect the power cord to the AC adapter.

4.Plug the power cord into a suitable power outlet. The orange battery charge 1 indicator turns on when you connect AC power.

5.Press the power button located just above the Pause button on the keyboard. The green power indicator turns on when the power is turned on.

6.After a logo screen and several seconds of power-on testing, the computer loads the Windows 98 operating system.

7.As this is the first time you have used your computer, Windows begins by running the Windows 98 Setup Wizard.

1-2

Setting Up Windows 98

Windows 98 is pre-installed on your computer, including the special drivers and

software used by built-in components such as the audio and video system, the 1 modem, and the PC card slot. The Windows Setup program lets you enter personal

data such as your name, the date and time in your location, and so on. It takes just a few minutes to complete. The setup process has four steps:

Getting started

This section asks for your name.

Registration

This section configures your modem

Windows License

This section asks you to accept the Windows License Agreement and to enter the Windows Product Key

Final Settings

This section checks the date and time in your location, and then completes the configuration of your system

Once you start the system for the first time, be sure to complete the setup program. Windows does not display the Setup Wizard the next time you turn on the computer.

About Windows Properties Dialog Boxes

In this manual you are often asked to open a Component Properties dialog box, such as the Modem Properties dialog box, or the Display Properties dialog box. These dialog boxes let you make changes to the configuration and operation of the component by clicking check boxes or selecting radio buttons. To open a Property dialog box, click the Start button in the taskbar at the foot of the Windows display. Select Settings - Control Panel. In the Control Panel window, double-click on an icon to display a Properties dialog box, or similar window, for the component or feature represented by that icon. Some of the Properties dialog boxes that are used to configure components in your computer include:

Display

Modem

System

Turning Off Your Computer

When you’re finished using your computer, turn it off with the following steps:

1.Click the Start button in the taskbar and click on Shut Down from the Start menu.

2.In the Shut Down Windows dialog box, check the Shut down item and then click the OK button. The power indicator turns off.

3.Close the cover to keep the screen and keyboard clean and protected.

You can shut down the computer with the power button using the steps below:

1.From the Start menu, select Settings – Control Panel and double-click the

Power Management icon.

2.In the Power Management Properties dialog box, click the Advanced tab.

3.Select Shutdown in the drop down menu for “When I press the power button on my computer”, and then click Apply and OK.

If you have not saved a file, a dialog box appears prompting you to save the file.

Don’t turn off your computer if status indicators show that the

computer is still accessing data on the hard disk drive, the floppy disk drive or the CD-ROM drive. Data may be lost or damaged.

After turning off the computer wait at least five seconds before turning the computer back on. Turning the computer off and on without a pause can damage the system.

Since this is your first session using the computer, it’s a good idea to leave the AC adapter connected to the computer until the internal battery is fully charged. The orange battery charge indicator changes to green when the battery is fully charged.

CHAPTER 2

Basic Operations

2

This chapter describes some of the basic operations of your computer such as using the keyboard, adjusting the display, and so on.

Powering the Computer

You can operate your computer by using the AC adapter to connect to a suitable power outlet. You can also power the computer by the internal Lithium-Ion battery.

Whenever you use the AC adapter to power the computer, the internal battery automatically begins recharging. Recharging continues whether the computer is turned on or off.

Refer to Chapter 3 Battery and Power Management for a full description of battery charging and related information.

2-1

Power and Battery Indicators

For proper operations it is important to understand the operation of the power and 2 battery indicators located beside the right-side hinge of the upper cover.

Resetting the System

You may need to reset the system after adding hardware or software so that your computer recognizes newly installed devices or software. When the message appears after the installation, click OK, Yes, etc., to restart Windows 98.

You can also restart Windows 98 from the Start menu. Select Shut Down, then

Restart.

Warm Boot (Software Reset)

If the system is locked up because of a software problem, you can reset or reboot the system by pressing the Ctrl+Alt+Del keys simultaneously. Press the Ctrl+Alt+Del keys again to restart the computer.

Resetting may cause data loss. Use the software reset only if the normal Windows 98 Shut Down does not work because of software malfunction. Although resetting does not damage the system, you may lose the data you are processing.

Power Switch

You can turn off the computer with the power switch if the system has hardware or software problems so that you can’t use the Windows Shut Down command or the software reset. In this case, you need to hold the power button down for more than four seconds.

Reset Switch

If all other methods fail, you can reset the computer by pressing the hardware reset switch. The hardware reset switch is in a recessed location on the base of the computer. Activate the switch with a straightened paper clip or similar implement.

Function Keys

On their own, the operation of the function keys is usually determined by the software application that you are running. In combination with the Fn key they create hot-keys that you can use to control some of the computer functions. Icons embossed on the function key keycaps indicate the hot-key function.

Embedded Keypad

The numeric keypad is embedded in some of the right-side alphanumeric keys. The keypad functions are embossed in the upper right corner of the keypad keycaps. You activate the embedded numeric keypad by pressing the Num Lk key (press Fn+Insert). Repeat the keystroke to turn off the embedded keypad.
