Wireless Communications with Bluetooth®
The following section only applies when the ZBR3 Bluetooth Radio
(FCC ID:
“Bluetooth” is a worldwide standard for the exchange of data between two devices via radio frequencies. Bluetooth radios are relatively low powered to help prevent interference with other devices running at similar radio frequencies. This limits the range of a Bluetooth device to about 10 meters (about 32 feet).
Both the printer and the device it communicates with must follow the Bluetooth standard.
Bluetooth Networking OverviewBluetooth software is always running in the background, ready to respond to connection requests. One device (known as the master or the client) must request a connection with an- other. The second device (the slave or the server) then accepts or rejects the connection. A Bluetooth enabled RW 420 printer will normally act as a slave creating a miniature network with the terminal sometimes referred to as a “piconet.”
For the most part, communications using Bluetooth are initiated and processed without any operator intervention.
Each Bluetooth enabled RW 420 printer has a unique Blue- tooth Device Address (BDA) loaded into its radio module when manufactured.
Exposure to Radio Frequency Radiation
The radiated output power of this internal Bluetooth radio is far below the FCC radio frequency exposure limits. Nevertheless, this Bluetooth radio must be used in such a manner that the antenna is 2.5 cm. or further from the human body.
The radio and antenna are mounted internally in this printer such that when the printer is worn with the back of the printer
