3.1 Infrared Communication
The BHT has an integrated infrared (IR) communications device which enables wire-
less transfer of programs and data between the BHT and the host computer and
between the BHTs, instead of the conventional wire transfer.
The IR communications device features the following:
•Wireless communications
•Small and lightweight design
•High transmission speed
•Freedom from the codes/regulations and licenses which differ from country to
country, unlike radio devices
The BHT may communicate with other IrDA-compliant equipment just by aligning their
IR ports with each other. The effective IR range and IR port angle may differ depending
upon the target equipment, so observe the instructions given in manuals furnished
with such equipment.

If IR transfer fails, bring the BHT closer to the target station or change the IR port

angle, and try again.
