109Chapter 3. Communications Operations of the BHT-100Q/100B3.1 Infrared CommunicationThe BHT has an integrated infrared (IR) communications device which enables wire-less transfer of programs and data between the BHT and the host computer andbetween 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 tocountry, unlike radio devicesThe BHT may communicate with other IrDA-compliant equipment just by aligning theirIR ports with each other. The effective IR range and IR port angle may differ dependingupon the target equipment, so observe the instructions given in manuals furnishedwith such equipment.If IR transfer fails, bring the BHT closer to the target station or change the IR portangle, and try again.
