Do not move either device during IrDA
communication as it may interrupt
data transmission.
INFRARED PORT
Infrared IrDA-compatible communication
is a function that allows for wireless data
transfer between your notebook and other
IrDA-compatible devices. Examples of IrDA-
compatible devices are another computer or a
printer. When carrying out this kind of com-
munication, both devices must be set so their
infrared ports are directly facing each other
without obstructions. A distance of 6" to 36"
between the device ports is ideal. Dirt or
scratches on the lens of your notebook or the
other device will degrade performance.
With Windows 98 SE, you can use the Infrared
Recipient program for infrared file transfers.
LapLink Professional software can also be used
for infrared file transfers. See your online help
for more information.
The following conditions may interfere with
infrared communications:
■
When the infrared communication ports
are not directly facing each other, or some
obstacle is between them.
■
When the infrared communication ports are
too far apart.
■
When a television or radio remote control
unit, or a wireless headphone is being
used nearby.
■
When a strong light such as direct sunlight,
fluorescent light, or incandescent light shines
on the port.

The internal modem is not intended for
use with Digital PBX systems. Do not
connect the internal modem to a digital
PBX as it may cause serious damage to
the internal modem or your entire note-
book. Consult your PBX manufacturer’s
documentation for details. Some hotels
have Digital PBX systems. Be sure to find
out BEFORE you connect your modem.
