Bluetooth™ Networking Overview
“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 interfer-
ence with other devices, limiting the range of a Bluetooth
device to about 10 meters (about 32 feet).
Exposure to Radio Frequency Radiation
The radiated output power of this internal wireless radio is
far below the FCC radio frequency exposure limits. Never-
theless, this Bluetooth radio must be used in such a man-
ner that the antenna is 2.5 cm or further from the human
body.
The radio and antenna are mounted internally in this
printer in such a way that, when the printer is used in a
standard configuration (belt clip, soft case, shoulder
strap), the 2.5 cm distance from the users body will be
met. Do not use the printer in an unauthorized manner.
The internal wireless radio operates within guidelines
found in radio frequency safety standards and recom-
mendations. The level of energy emitted is far less than the
electromagnetic energy emitted by wireless devices such
as mobile phones.
Each Encore with the Bluetooth option has a unique
Bluetooth Device Address (BDA) loaded into its radio mod-
ule when manufactured.
Bluetooth software runs in the background in order to
respond to connection requests, which one device (known
as the master or the client) must request from another. The
second device (the slave or the server ) then accepts or
rejects the connection. A Bluetooth enabled Encore will
always act as a slave device. The miniature network this
connection creates is sometimes referred to as a “piconet”
and can consist of several Bluetooth enabled devices.
For the most part, communications using the Bluetooth
protocol are initiated and processed without any operator
intervention, much like the IrDA system described previ-
ously.
