Infrared Communication
The infrared port of this unit can be used to exchange data with another ST4ex/ST4i, or
with another device equipped with infrared communication capabilities. Remember that
the two infrared ports must be pointed directly at each other when performing
communication. The distance between the two infrared ports must be less than 20 cm.
For infrared data communication with another device, the other device must confirm with
IrDA 1.2 standards, and it must specifically support infrared data communication with
ST4ex/ST4i.
IMPORTANT
●
Make sure the units do not move while infrared data communication is in progress.
●
Infrared data communication may be impossible under strong sunlight or inverter
type fluorescent lighting.
●
Infrared data communication problems can be caused by the distance and angle
between the two ports, outdoor sunlight, and low battery level.
●
Dirt and dust on the infrared port surface can cause communication errors and
other problems. Use a soft, dry cloth to wipe off the dirt and dust.
