Chapter 2. Getting Started the BHT and System Mode

In addition, the BHT-7500S/7500W may operate in a radio communications system

(spread-spectrum communication) by connecting with access points by a wireless

local area network (wireless LAN).

●Access point: Wireless communications base unit for the BHT-7500S/7500W

●Ethernet port: Connects the access points and Ethernet

Radio communications system (only BHT-7500S/7500W connectable)
