For Better Communications - Fujitsu l2010 User Manual

For better communications

This personal computer may not operate properly according to the particular operating environment.
Strictly observe the following precautions when installing the main unit of the computer:
• Since this personal computer and equipment compliant with IEEE802.11a differ in operation
frequency, it is not possible to communicate between both. Be careful of this.
• The recommended wireless communications distance is within a line-of-sight radius of 25 meters.
For reasons related to the characteristics of the wireless LAN, however, the actual communications
distance depends on the structure or materials type of building in which the wireless LAN function
is to be used, the presence/absence of obstructions, the types of software to be used, installation
status, radio-wave status, or other operating conditions. Decreases in communications speed or
a communications failure may also occur.
• Distance the main unit of this personal computer from other electric appliances. If the main unit
of the person computer is installed near a powered-on electric appliance, the computer may not
be able to communicate properly or trouble may occur in the electric appliance.
If the computer is unable to communicate properly, change the channel to be used or the installation
location. During the use of a microwave oven or other equipment generating strong high-frequency
energy, in particular, the personal computer may be highly susceptible to the energy and unable
to communicate properly.
• If a broadcasting station or wireless communications equipment is present nearby and this prevents
the computer from communicating properly, moving the main unit of the computer is suggested.
Radio interference may also occur if the intensity of ambient radio waves is too high.
• About radio interference with the Bluetooth
Since the Bluetooth
TM
Bluetooth is used near the main unit of this personal computer, radio interference may occur,
leading to decreases in communications speed or to a connection failure. If these events actually
occur, undertake the following countermeasures:
– Space the Bluetooth
meters.
– Within a distance of 10 meters, turn off the power of either the Bluetooth
the personal computer.
