Ergonomic Considerations
n 9 N
Ergonomic Considerations
You will be using your computer as a portable device in a variety of environments. Whenever possible, you should attempt
to take account of the following ergonomic considerations for both stationary and portable environments:
❑ Position of your computer – Place the computer directly in front of you. Keep your forearms horizontal, with your wrists
in a neutral, comfortable position while using the keyboard or the pointing device. Let your upper arms hang naturally at
your sides. Take frequent breaks while using your computer. Excessive use of the computer may strain eyes, muscles, or
tendons.
❑ Furniture and posture – Sit in a chair with good back support. Adjust the level of the chair so your feet are flat on the
floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and avoid slouching forward or leaning
far backwards.
Before Use >
Ergonomic Considerations
n 10 N
❑ Viewing angle of the computer display – Use the display tilting feature to find the best position. You can reduce eye
strain and muscle fatigue by adjusting the tilt of the display to the proper position. Adjust the brightness level of the display
as well.
❑ Lighting – Choose a location where windows and lights do not cause glare and reflection on the display. Use indirect
lighting to avoid bright spots on the display. Proper lighting adds to your comfort and work efficiency.
❑ Positioning an external display – When using an external display, set the display at a comfortable viewing distance.
Make sure the display screen is at or slightly below eye level when you are sitting in front of the monitor.

Notes on Using the Wireless LAN Function
General notes on using the wireless LAN function
❑ In some countries, using WLAN products may be restricted by the local regulations (e.g. limited number of channels).
Before activating the WLAN function, read the Safety Information carefully.
❑ The IEEE 802.11a standard and the IEEE 802.11n standard are not available on ad-hoc networks.
❑ The 2.4 GHz band used by wireless LAN compatible devices is also used by other various devices. Although technologies
to minimize interference from other devices that use the same band are employed on wireless LAN compatible devices,
such interference may cause lower communication speed, narrower communication range, or broken wireless
connections.
❑ The communication speed and range may vary depending on the following conditions:
❑ Distance between communication devices
❑ Existence of obstacles between devices
❑ Device configuration
❑ Radio conditions
❑ Ambient environment that includes existence of walls and materials of such walls
❑ Software in use
❑ Communications may be cut off depending on radio conditions.
❑ Actual communication speed may not be as fast as the one displayed on your computer.
❑ Deploying WLAN products compliant with different standards that use the same band on the same wireless network may
reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed
to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a
different standard that uses the same band. When the communication speed is not as fast as expected, changing the
wireless channel on the access point may increase the communication speed.

Note on the data encryption
The WLAN standard includes the encryption methods: Wired Equivalent Privacy (WEP), which is a security protocol, Wi-Fi
Protected Access 2 (WPA2), and Wi-Fi Protected Access (WPA). Proposed jointly by the IEEE and Wi-Fi Alliance, both WPA2
and WPA are specifications of standards based on interoperable security enhancements that increase the level of data
protection and access control for existing Wi-Fi networks. WPA is designed to be forward compatible with the IEEE 802.11i
specification. It utilizes the enhanced data encryption Temporal Key Integrity Protocol (TKIP) in addition to user authentication
using 802.1X and Extensible Authentication Protocol (EAP). Data encryption protects the vulnerable wireless link between
clients and access points. Besides that, there are other typical LAN security mechanisms to ensure privacy, such as:
password protection, end-to-end encryption, virtual private networks, and authentication. WPA2, the second generation of
WPA, provides stronger data protection and network access control and is also designed to secure all versions of 802.11
devices, including 802.11b, 802.11a, 802.11g, and 802.11n standards, multi-band and multi-mode. In addition, based on the
ratified IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of
Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1X-based authentication. WPA2
is backward compatible with WPA.
