Setting up your work space
Establishing a comfortable work site is important for you and your computer. A poor work environment or stressful work habits can result in discomfort or serious injury from repetitive strain to your hands, wrists or other joints. Proper ambient conditions should also be maintained for the computers operation. This section discusses the following topics: General conditions Placement of the computer and peripheral devices Seating and posture Lighting Work habits
In general, if you are comfortable, so is your computer, but read the following to make sure your work site provides a proper environment. Make sure there is adequate space around the computer for proper ventilation. Make sure the AC power cord connects to an outlet that is close to the computer and easily accessible. The temperature should be 5 to 35 degrees Centigrade (41 to 95 degrees Fahrenheit) and the relative humidity should be 20 to 80 percent. Avoid areas where rapid or extreme changes in temperature or humidity may occur. Keep the computer free of dust, moisture, and exposure to direct sunlight. Keep the computer away from heat sources, such as electric heaters. Do not use the computer near liquids or corrosive chemicals. Do not place the computer near objects that create strong magnetic fields (e.g., stereo speakers). Do not operate the computer in close proximity to a mobile phone. Leave ample ventilation room for the fan. Do not block the vents.

Placement of computer

Position the computer and peripheral devices to provide comfort and safety.
Set the computer on a flat surface at a comfortable height and distance. The display should be no higher than eye level to avoid eye strain. Place the computer so that it is directly in front of you when you work and make sure you have adequate space to easily operate other devices. Allow adequate space behind the computer to let you freely adjust the display. The display should be angled to reduce glare and maximize visibility. If you use a paper holder, set it at about the same height and distance as the computer.

Seating and posture

The height of your chair in relation to the computer and keyboard as well as the support it gives your body are primary factors in reducing work strain. Refer to the following tips and to figure 3-1.

BELOW EYE LEVEL

FOOT REST

90 ANGLES

Figure 3-1 Posture and positioning of the computer Place your chair so that the keyboard is at or slightly below the level of your elbow. You should be able to type comfortably with your shoulders relaxed. Your knees should be slightly higher than your hips. If necessary, use a foot rest to raise the level of your knees to ease pressure on the back of your thighs. Adjust the back of your chair so it supports the lower curve of your spine. Sit straight so that your knees, hips and elbows form approximately 90 degree angles when you work. Do not slump forward or lean back too far.

Writing CDs on CD-RW/DVD-ROM drive
You can use the CD-RW/DVD-ROM drive to write data to either CD-R or CDRW discs. The following applications for writing are supplied: RecordNow! and DLA, licensed by Sonic Solutions.
NOTE: CD-R discs can be written to only once. CD-RW discs can be rewritten many times.
Important message (CD-RW/DVD-ROM drive)
Before you write or rewrite to CD-RW disc, read and follow all setup and operating instructions in this section. If you fail to do so, the CD-RW/DVD-ROM drive may not function properly, and you may fail to write or rewrite, lose data or incur other damage.
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: TAIYOYUDEN CO., LTD. Mitsui Chemicals Inc. MITSUBISHI CHEMICAL CORPORATION RICOH Co., Ltd. Hitachi Maxell Ltd. CD-RW: MITSUBISHI CHEMICAL CORPORATION RICOH Co., Ltd. The following special media recommended the next manufacturers. 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. CD-RW can generally be rewritten about 1,000 times. However, the actual number of rewrites is affected by the quality of the media 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 HDD access speed. They may cause unstable operation and damage data. Write from the computers HDD 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 RecordNow! has not been confirmed. Therefore, operation with other software cannot be guaranteed.

Using the microphone

Your computer has a built-in microphone that can be used to record monaural sounds into your applications. It can also be used to issue voice commands to applications that support such functions.
Writing CD/DVDs on DVD Super Multi drive supporting DVD+R DL Modem Since your computer has a built-in microphone and speaker, feedback may be heard under certain conditions. Feedback occurs when sound from the speaker is picked up in the microphone and amplified back to the speaker, which amplifies it again to the microphone. This feedback occurs repeatedly and causes a very loud, high-pitched noise. It is a common phenomenon that occurs in any sound system when the microphone input is output to the speaker (throughput) and the speaker volume is too loud or too close to the microphone. You can control throughput by adjusting the volume of your speaker or through the Mute function in the Master Volume panel. Refer to your Windows documentation for details on using the Master Volume panel.
This section describes how to connect and disconnect the internal modem to and from a telephone jack. NOTE: The internal modem does not support voice functions. All data and fax functions are supported. CAUTIONS: 1. In case of a lightning storm, unplug the modem cable from the telephone jack. 2. Do not connect the modem to a digital telephone line. A digital line will damage the modem.

If you continue to use the computer while the Battery indicator flashes, the computer enables Hibernation mode (so you dont lose data) and automatically turns off. NOTES: The computer enters Hibernate mode only if Hibernation is enabled in two places: the Hibernate tab in Power Options and Setup Action tab in TOSHIBA Power Saver. You must recharge a battery pack when it becomes discharged.

Procedures

To recharge a battery pack while it is installed in the computer, connect the AC adaptor to the DC IN socket and plug the other end into a working outlet. The Battery indicator glows amber when the battery is being charged. CAUTION: Use only the computer connected to an AC power source or charge the battery pack. Do not attempt to charge the battery pack with any other charger.
The following table shows the approximate time required to fully charge a discharged battery. Charging time (hours) Battery type Battery pack (6 cell) Battery pack (12 cell) RTC battery Power on 8 hours or later 8 hours or later 24 hours Power off 4 hours 4 hours Dont charge
NOTE: The charging time when the computer is on is affected by ambient temperature, the temperature of the computer and how you use the computer. If you make heavy use of external devices, for example, the battery might scarcely charge at all during operation. Refer also to the section Maximizing battery operating time.

Battery charging notice

The battery may not charge right away under the following conditions: The battery is extremely hot or cold. If the battery is extremely hot, it might not charge at all. Also, to ensure the battery charges to its full capacity, charge the battery at room temperature of 10 to 30C (50 to 86F). The battery is nearly completely discharged. Leave the AC adaptor connected for a few minutes and the battery should begin charging.
The Battery indicator may show a rapid decrease in battery operating time when you try to charge a battery under the following conditions:
The battery has not been used for a long time. The battery has completely discharged and been left in the computer for a long time. A cool battery is installed in a warm computer.
In such case, follow the steps below. 1. Fully discharge the battery by leaving it in the computer with the power on until the power automatically shuts off. 2. Plug in the AC adaptor. 3. Charge the battery until the Battery indicator glows green. Repeat the steps two or three times until the battery recovers normal capacity. NOTE: Leaving the AC adaptor connected will shorten battery life. At least once a month, run the computer on battery power until the battery is fully discharged, then recharged the battery.
Monitoring battery capacity
Remaining battery power can be monitored in TOSHIBA Power Saver. NOTES: 1. Wait at least 16 seconds after turning on the computer before trying to monitor the remaining operating time. The computer needs this time to check the batterys remaining capacity and to calculate the remaining operating time, based on the current power consumption rate and remaining battery capacity. The actual remaining operating time may differ slightly from the calculated time. 2. With repeated discharges and recharges, the batterys capacity will gradually decrease. Therefore, an often used, older battery will not operate for as long as a new battery even when both are fully charged. In this case, TOSHIBA Power Saver will indicate a 100% charge for both the old and new battery, but the displayed estimated time remaining will be shorter for the older battery.

All computer equipment generates radio frequency signals. The FCC regulates the amount of signals a computing device can allow past its shielding. A Class A device is sufficient for office use. Class B provides a more stringent classification for home equipment use. TOSHIBA portable computers comply with Class B computing device regulations. Random Access Memory (RAM): High speed memory within the computer circuitry that can be read or written to.

restart
restart: Resetting a computer without turning it off (also called warm boot or soft reset). To restart the computer, press Ctrl + Alt + Del while the computer is on. See also boot. RCA jack: A single-pin connector that carries composite video signals, which include both contrast and color information. See also S-video. RGB: Red, green, and blue. A device that uses three input signals, each activating an electron gun for a primary additive color (red, green, and blue) or port for using such a device. See also CRT. RJ11: A modular telephone jack. ROM: Read Only Memory: A nonvolatile memory chip manufactured to contain information that controls the computers basic operation. You cannot access or change information stored in ROM. RS-232C: The Electronic Industries Association (EIA) interface standard that describes the 25-pin connector interface and control, data, and status signals that allow asynchronous communications between computers, printers, communications and other peripheral devices. serial: The handling of data bits one after the other. serial communications: A communications technique that uses as few as two interconnecting wires to send bits one after another. serial interface: Refers to a type of information exchange that transmits information sequentially, one bit at a time. Contrast: Parallel interface. serial port: A communications port to which you can connect devices, such as a modem, mouse, or serial printer. SIO: Serial Input/Output. The electronic methodology used in serial data transmission. soft key: Key combinations that emulate keys on the IBM keyboard, change some configuration options, stop program execution, and access the numeric keypad overlay. software: The set of programs, procedures and related documentation associated with a computer system. Specifically refers to computer programs that direct and control the computer systems activities. See also hardware. stop bit: One or more bits of a byte that follow the transmitted character or group codes in asynchronous serial communications. subpixel: Three elements, one red, one green and blue (RGB), that make up a pixel on the color LCD. The computer sets subpixels independently, each may emit a different degree of brightness. See also pixel.
