Telephone company procedures
The goal of the telephone company is to provide you with the best service it can. In order to do this, it may occasionally be necessary for them to make changes in their equipment, operations, or procedures. If these changes might affect your service or the operation of your equipment, the telephone company will give you notice in writing to allow you to make any changes necessary to maintain uninterrupted service.

If problems arise

If any of your telephone equipment is not operating properly, you should immediately remove it from your telephone line, as it may cause harm to the telephone network. If the telephone company notes a problem, they may temporarily discontinue service. When practical, they will notify you in advance of this disconnection. If advance notice is not feasible, you will be notified as soon as possible. When you are notified, you will be given the opportunity to correct the problem and informed of your right to file a complaint with the FCC. In the event repairs are ever needed on your modem, they should be performed by TOSHIBA Corporation or an authorized representative of TOSHIBA Corporation.

Disconnection

If you should ever decide to permanently disconnect your modem from its present line, please call the telephone company and let them know of this change.

Fax branding

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device to send any message via a telephone fax machine 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, other entity or individual sending the message and the telephone number of the sending machine or such business, other entity or individual. In order to program this information into your fax modem, you should complete the setup of your fax software before sending messages.
Instructions for IC CS-03 certified equipment

Writing CDs on DVD-ROM&CD-R/RW drive
Depending on the type of drive installed, you may be able to write CDs. The DVD-ROM&CD-R/RW drive lets you write as well as read CD-ROMs. Observe the precautions in this section to ensure the best performance for writing CDs. For information on loading and unloading CDs refer to the Using optical disk drives section. Refer to the Writable discs, Chapter 2 for details about the types of writable CD/DVD discs.
When writing to media using an optical drive, always connect the AC adaptor to a power plug socket or power source to ensure maximum performance. If data is written powered by the batteries, writing may sometimes fail due to low battery power and data loss may occur.
Before writing or rewriting
Please observe the following points when you write or rewrite the data. We recommend the following manufacturers of CD-R and CD-RW media. Media quality can affect write or rewrite success rates. CD-R: TAIYO YUDEN CO., LTD. MITSUBISHI CHEMICAL CORPORATION RICOH Co., Ltd. Multi-Speed and High-Speed CD-RW: MITSUBISHI CHEMICAL CORPORATION RICOH Co., Ltd. Ultra-Speed CD-RW: MITSUBISHI CHEMICAL CORPORATION TOSHIBA has confirmed the operation of CD-R and CD-RW media of the manufacturers above. Operation of other media cannot be guaranteed. The actual number of rewrites to CD-RW is affected by the quality of the disc and the way it is used. Be sure to connect the AC adaptor when you write or rewrite. Be sure to close all other software programs except the writing software. Do not run software such as a screen saver which can put a heavy load on the CPU. Operate the computer at full power. Do not use power-saving features. Do not write while virus check software is running. Wait for it to finish, then disable virus detection programs including any software that checks files automatically in the background. Do not use hard disk utilities, including those intended to enhance hard disk drive access speeds. They may cause unstable operation and damage data. Write from the computer's hard disk drive to the CD. Do not try to write from shared devices such as a LAN server or any other network device. Writing with software other than Sonic RecordNow! has not been confirmed. Therefore, operation with other software cannot be guaranteed.

Display Controller and Modes

Display controller

The display controller interprets software commands into hardware commands that turn particular parts on the screen on or off. 15.4" WXGA, 1280 horizontal 800 vertical pixels Because of the LCDs increased resolution, lines may appear broken in DOS mode. A high-resolution external monitor connected to the computer can display up to 2,048 horizontal and 1,536 vertical pixels at up to 16M colors. The display controller also controls the video mode, which uses industry standard rules to govern the screen resolution and the maximum number of colors that can be displayed on screen. Software written for a given video mode will run on any computer that supports the mode.

Video modes

The computer supports video modes defined in the tables below. If your application offers a selection of mode numbers that do not match the numbers on the table, select a mode based on mode type, resolution, character matrix, number of colors and refresh rates. Also, if your software supports both graphics and text modes, the screen display may appear to operate faster using a text mode.

Appendix D

S-registers
S-registers contain the settings that determine how a number of functions of the internal modem operate. For example, how many times to let the telephone ring before the modem answers and how long to wait before it hangs up if a connection fails. You can also customize certain AT commands such as the escape sequence and command line termination. The contents of the registers are changed automatically when you modify corresponding settings in your communication software. If you choose, however, you can display and edit the contents of the registers manually when the modem is in command mode. If the value is out of the acceptable range, then an error is generated. This chapter describes the settings for each S-register.

S-register values

The format for displaying the value of an S-register is: ATSn? where n is the register number. After you type in the register press Enter. The format for modifying the value of an S-register is: ATSn=r where n is the register number, and r is the new register value. After you type in the register and its new value press Enter. Some registers vary from one country/region to another.

Auto answer ring number

This register determines the number of rings the modem will count before automatically answering a call. Enter 0 (zero) if you do not want the modem to automatically answer at all. When disabled, the modem can only answer with an ATA command.
Range: 0-255 Default: 0 Units: rings

Ring counter

This register is read only. The value of S1 is incremented with each ring. If no ring occurs over a six-second interval, this register is cleared. Range: 0-225 Default: 0 Units: rings
AT escape character (user defined)
This register determines the ASCII values used for an escape sequence. The default is the + character. The escape sequence allows the modem to exit data mode and enter command mode when on-line. Values greater than 127 disable the escape sequence. Range: 0-255, ASCII decimal Default: 43 Units: ASCII

Using the Hard Disk Drive (HDD) Protection
This computer has a function for reducing the risk of damage on hard disk drive. Using the acceleration sensor built in the computer, HDD Protection detects vibration, shocks, and those signs in the computer, and automatically moves the HDD (Hard Disk Drive) head to the safe position to reduce the risk of damage that could be caused to the disk by head-to-disk contact. This function does not guarantee that the hard disk drive will not be damaged. A secondary hard disk drive fitted to the computer is not supported by the HDD protection function.
When vibration is detected, the following message is displayed, and the icon in the notification area of the taskbar is changed to the protection state. This message is displayed until the OK button is pressed or 30 seconds pass. When vibration subsides, the icon returns to the normal state.

This function can be set to four levels. The sensitivity levels in which vibrations, impacts and their similar signs are detected can be set to OFF, 1, 2 and 3 in ascending order. Level 3 is recommended for better protection of the computer. However, when the computer is used as handheld or in other unstable conditions, setting the detection level to 3 could result in frequent execution of HDD Protection, which will slow HDD reading and writing. Set a lower detection level when the speed of HDD reading and writing is a priority. Different detection levels can be set depending on whether the computer is used as handheld or mobile usages, or whether it is used in a stable environment such as on a table in the workplace or at home. By setting different detection levels for the computer depending on whether it runs with the AC power (desktop) or with batteries (handheld or mobile usage), the detection level automatically switches according to the power connection mode.

K: Taken from the Greek word kilo, meaning 1000; often used as equivalent to 1024, or 2 raised to the 10th power. See also byte and kilobyte. KB: See kilobyte. keyboard: An input device containing switches that are activated by manually pressing marked keys. Each keystroke activates a switch that transmits a specific code to the computer. For each key, the transmitted code is, in turn, representative of the (ASCII) character marked on the key. kilobyte (KB): A unit of data storage equal to 1024 bytes. See also byte and megabyte.
level 2 cache: See cache. Light Emitting Diode (LED): A semiconductor device that emits light when a current is applied. Liquid Crystal Display (LCD): Liquid crystal sealed between two sheets of glass coated with transparent conducting material. The viewing-side coating is etched into character forming segments with leads that extend to the edge of the glass. Applying a voltage between the glass sheets alters the brightness of the liquid crystal.
