CAUTION: Do not operate your portable computer for an extended period of time with the base resting directly on your body. With extended operation, heat can potentially build up in the base. Allowing sustained contact with the skin could cause discomfort or, eventually, a burn.

❑ Do not attempt to service the computer yourself. Always follow installation

instructions closely.

❑ Do not carry a battery in your pocket, purse, or other container where metal

objects (such as car keys) could short-circuit the battery terminals. The resulting excessive current follow can cause extremely high temperatures and may result in damage from burns.

❑ Be sure that noting rests on your AC adapter’s power cable and that the

cable is not located where it can be tripped over or stepped on.

❑ Place the AC adapter in a ventilated area, such as a desk top or on the floor,

when you use it to run the computer or to charge the battery. Do not cover the AC adapter with papers or other items that will reduce cooling; also, do not use the AC adapter while it is inside a carrying case.

❑ Use only the AC adapter and batteries that are approved for use with this

computer. Use of another type of battery or AC adapter may risk fire or explosion.

❑ Before you connect the computer to a power source, ensure that the voltage

rating of the AC adapter matches that of the available power source. 115 V/ 60 Hz in most of North and South America and some Far Eastern countries such as Taiwan. 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan. 230 V/50 Hz in most of Europe, the Middle East, and the Far East.

❑ If you use an extension cable with your AC adapter, ensure that the total

ampere rating of the products plugged in to the extension cable does not exceed the ampere rating of the extension cable.

❑ To remove power from the computer, turn it off, remove the battery, and dis-

connect the AC adapter from the electrical outlet.

❑ To help avoid the potential hazard of electric shock, do not connect or dis-

connect any cables or perform maintenance or reconfiguration of this product during an electrical storm.

Pursuant to FCC CFR 47, Part 68:

When you are ready to install or use the modem, call your local telephone company and give them the following information:

❑ The telephone number of the line to which you will connect the modem ❑ The registration number that is located on the device

The FCC registration number of the modem will be found on either the device which is to be installed, or, if already installed, on the bottom of the computer outside of the main system label.

❑ The Ringer Equivalence Number (REN) of the modem, which can vary. For

the REN of your modem, refer to your modem’s label.

The modem connects to the telephone line by means of a standard jack called the USOC RJ11C.

Type of service

Your modem is designed to be used on standard-device telephone lines. Connection to telephone company-provided coin service (central office implemented systems) is prohibited. Connection to party lines service is subject to state tariffs.

If you have any questions about your telephone line, such as how many pieces of equipment you can connect to it, the telephone company will provide this information upon request.

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.

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

1 The Industry Canada label identifies certified equipment. This certification

means that the equipment meets certain telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). 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.

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 coordinated by a representative 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.

Notes for Users in Australia and New Zealand

Modem warning notice for Australia

Modems connected to the Australian telecoms network must have a valid Austel permit. This modem has been designed to specifically configure to ensure compliance with Austel standards when the country/region selection is set to Australia. The use of other country/region setting while the modem is attached to the Australian PSTN would result in you modem being operated in a non-compliant manner. To verify that the country/region is correctly set, enter the command ATI which displays the currently active setting.

To set the country/region permanently to Australia, enter the following command sequence:

AT%TE=1 ATS133=1 AT & F AT & W AT%TE=0 AT Z

Failure to set the modem to the Australia country/region setting as shown above will result in the modem being operated in a non-compliant manner. Consequently, there would be no permit in force for this equipment and the Telecoms Act 1991 prescribes a penalty of $12,000 for the connection of non-permitted equipment.

Notes for use of this device in New Zealand

❑ The grant of a Telepermit for a device in no way indicates Telecom accep-

tance of responsibility for the correct operation of that device under all operating conditions. In particular the higher speeds at which this modem is capable of operating depend on a specific network implementation which is only one of many ways of delivering high quality voice telephony to customers. Failure to operate should not be reported as a fault to Telecom.

❑ In addition to satisfactory line conditions a modem can only work properly

if: (a) it is compatible with the modem at the other end of the call and (b) the application using the modem is compatible with the application at

the other end of the call - e.g., accessing the Internet requires suitable software in addition to a modem.

❑ This equipment shall not be used in any manner which could constitute a

nuisance to other Telecom customers.

❑ Some parameters required for compliance with Telecom’s PTC Specifica-

tions are dependent on the equipment (PC) associated with this modem. The associated equipment shall be set to operate within the following limits for compliance with Telecom Specifications:

(a) There shall be no more than 10 call attempts to the same number within

any 30 minute period for any single manual call initiation, and

(b) The equipment shall go on-hook for a period of not less than 30 seconds

between the end of one attempt and the beginning of the next.

apart.

❑ Immediately disconnect this equipment should it become physically dam-

aged, and arrange for its disposal or repair.

❑ The correct settings for use with this modem in New Zealand are as follows:

ATB0 (CCITT operation) AT&G2 (1800 Hz guard tone) AT&P1 (Decadic dialing make-break ratio = 33%/67%) ATS0=0 (not auto answer) ATS10=less than 150 (loss of carrier to hangup delay, factory default of 15

recommended) ATS11=90 (DTMF dialing on/off duration=90 ms) ATX2 (Dial tone detect, but not (U.S.A.) call progress detect)

❑ When used in the Auto Answer mode, the S0 register must be set with a

value of 3 or 4. This ensures: (a) a person calling your modem will hear a short burst of ringing before

the modem answers. This confirms that the call has been successfully switched through the network.

(b) caller identification information (which occurs between the first and

second ring cadences) is not destroyed.

❑ The preferred method of dialing is to use DTMF tones (ATDT...) as this is

faster and more reliable than pulse (decadic) dialing. If for some reason you must use decadic dialing, your communications program must be set up to record numbers using the following translation table as this modem does not implement the New Zealand “Reverse Dialing” standard.

Number to be dialed: 0 1 2 3 4 5 6 7 8 9 Number to program into computer: 0 9 8 7 6 5 4 3 2 1 Note that where DTMF dialing is used, the numbers should be entered nor-

mally.

❑ The transmit level from this device is set at a fixed level and because of this

there may be circumstances where the performance is less than optimal. Before reporting such occurrences as faults, please check the line with a standard Telepermitted telephone, and only report a fault if the phone performance is impaired.

❑ It is recommended that this equipment be disconnected from the Telecom

line during electrical storms.

❑ When relocating the equipment, always disconnect the Telecom line connec-

tion before the power connection, and reconnect the power first.

❑ This equipment may not be compatible with Telecom Distinctive Alert

cadences and services such as FaxAbility.

NOTE THAT FAULT CALLOUTS CAUSED BY ANY OF THE ABOVE CAUSES MAY INCUR A CHARGE FROM TELECOM

General conditions

Stress injury

Carefully read the Instruction Manual for Safety & Comfort. It contains informa- tion on prevention of stress injuries to your hands and wrists than can be caused by extensive keyboard use. Chapter 3, Getting Started, also includes information on work space design, posture and lighting that can help reduce physical stress.

Heat injury

◆ Avoid prolonged physical contact with the computer. If the computer is used

for long periods, its surface can become very warm. While the temperature will not feel hot to the touch, if you maintain physical contact with the computer for a long time (if you rest the computer on your lap, or if you keep your hands on the palm rest, for example) your skin might suffer low-heat injury.

◆ If the computer has been used for a long time, avoid direct contact with the

metal plate supporting the I/O ports. It can become hot.

◆ The surface of the AC adaptor can become hot when in use. This condition

does not indicate a malfunction. If you need to transport the AC adaptor, disconnect it and let it cool before moving it.

◆ Do not lay the AC adaptor on a material that is sensitive to heat. The mate-

rial could be damaged.

Pressure or impact damage

Do not apply heavy pressure to the computer or subject it to strong impact. Excessive pressure or impact can cause damage to computer components or otherwise cause malfunctions.
