Instructions for IC CS-03 certified equipment

1NOTICE: 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.

2The user manual of analog equipment must contain the equipment’s Ringer Equivalence Number (REN) and an explanation notice similar to the following:

The Ringer Equivalence Number (REN) of this device is 0.9B.

General Precautions

Toshiba computers are designed to optimise safety, minimise strain and withstand the rigors of portability. However, certain precautions should be observed to further reduce the risk of personal injury or damage to the computer. Be certain to read the general precautions below and to note the cautions included in the text of the manual.

Stress injury

Carefully read the Safety Instruction Manual. It contains information on prevention of stress injuries to your hands and wrists than can be caused by extensive keyboard use. The User's Guide also includes information on work space design, posture and lighting that can help reduce physical stress.

Heat Warning

The base of the PC can become very warm; while the temperature will not be too hot to the touch, prolonged physical contact may result in a temporary heat imprint on the skin. It is recommended that prolonged physical contact is avoided.

Also, 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.

Mobile phones

Use of mobile phones can interfere with the PC sound system. The PC operation is not impaired but it is recommended that a distance of 30cm is maintained between the PC & the mobile phone.

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.

PC card overheating

Some PC cards can become hot with prolonged use. If two cards are installed, both can become hot even if only one is used extensively. Overheating of a PC card can result in errors or instability in the PC card operation. Also, be careful when you remove a PC card that has been used for a long time.

Front with the display open

The caps lock light glows when you press the Caps Lock key. When this light is on, pressing a letter key on the keyboard produces an uppercase (capital) letter.

The scroll lock light glows when the scroll lock function is active. The scroll lock key temporarily prevents the display from updating and controls the way the cursor control keys work with some programs. It’s up to the program to implement this behavior. Many programs ignore the scroll lock setting.

The cursor control mode light glows when the cursor control overlay is on. When this light is on, pressing an overlay key moves the cursor in the direction of the white arrow printed on the left top of the key instead of the letter printed on the key.
