Setting Up an Infrared Transmission
For information about using infrared software, refer to your
operating system Help file.
To set up infrared devices for optimal transmission:
■ Prepare the infrared ports on both devices for transmission.
■ Position the devices so that their infrared ports face one
another at a distance no greater than 1 meter (3.3 feet).
■ Position the ports so that they face one another directly.
Because the maximum capture angle is 30 degrees, the
ports must be aligned no more than 15 degrees off-center.
■ Shield the ports from direct sunlight, flashing incandescent
light, and energy-saving fluorescent light.
■ Be sure that no signals from remote control or other wireless
devices, such as headphones or audio devices, aim at a port.
■ 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/standby 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.
