Setting Up an Infrared Transmission

For information about using infrared software and enabling or
disabling infrared ports, refer to the operating system Help files
and to the documentation included with the external infrared
device.
To set up 2 infrared devices, such as the notebook and an
optional printer, for optimal transmission:
Position the devices so that their infrared ports face each
other at a distance of no more than 3.3 feet (1 meter).
Position the ports so that they face each other directly. The
maximum capture angle is 30 degrees, so the ports must be
aligned no more than 15 degrees off center vertically or
horizontally.
Shield the ports from direct sunlight, flashing incandescent
light and fluorescent light.
Be sure that signals from a remote control or other wireless
device (such as a cell phone, a headset, or an audio device)
do not aim at either port.
During the transmission, do not move either device and do
not allow objects or movement to disrupt the beam.

Avoiding Standby While Using Infrared

Standby is not compatible with infrared transmission. If the
notebook is in Standby, an infrared transmission cannot be
initiated.
If Standby initiates during an infrared transmission, the
transmission stops. To resume from Standby, briefly press
the power button. The transmission resumes when the notebook
resumes from Standby.
