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).
Bluetooth compliant printers equipped are identified by
a small “Bluetooth” logo under the unit’s IR window.
Exposure to Radio Frequency Radiation
The radiated output power of this internal wireless 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 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 de-
vices such as mobile phones.
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 cre-
ated by this connection is sometimes referred to as a
“piconet” and can consist of several Bluetooth enabled
devices.
Each Encore with the Bluetooth option has a unique
Bluetooth Device Address (BDA) loaded into its radio mod-
ule when manufactured.
