During the transmission, do not move either device and do
not allow objects or movement to disrupt the beam.

Using Standby with Infrared

Standby is not compatible with infrared transmission. If the
notebook is in Standby, an infrared transmission cannot be
initiated. If Standby is initiated during an infrared transmission,
the transmission stops. To resume from Standby, press the power
button. The transmission resumes when the notebook resumes
from Standby. However, any program that was using the infrared
transmission when Standby was initiated may not continue at the
point it was stopped. For example, if a program was printing
when Standby was initiated, the program resumes transmission
after the notebook resumes, but the print job may not resume.

an optional mini PCI device. For more information on using your

supported through an optional integrated module. For more
