Data transmission
problem.
Direct sunlight,
energy-saving
fluorescent light, or
flashing incandescent
light is close to the
infrared connections.
Remove the interfering
light source(s), or move
the infrared ports closer
together, or select a
slower fixed baud rate
for each device.
Interference from other
infrared-equipped
devices.
Keep infrared-equipped
remote control units,
such as wireless
headphones, pointed
away from the infrared
connection.
Dirty infrared lens. Clean the lens with a
lint-free cloth.
Distance. Move the infrared ports
closer together. They
should be no more than
3 feet (1 meter) apart.
Movement. Do not move either
unit during data
transmission.
Orientation. Adjust the infrared
ports so that the
maximum capture angle
is 30 degrees. Ports
must be aligned so
they’re no more than
15 degrees off center.
Physical obstruction. Remove any objects
between the two
infrared ports that
could be interfering with
the line-of-sight data
transmission.
