QL 420 User’s Guide

27

This device complies with the essential requirements of the R&TTE
Directive 1999/5/EC. The following test methods have been applied in
order to prove presumption of compliance with the R&TTE Directive 1999/
5/EC:

• EN 60950: 2000
Safety of Information Technology Equipment
• EN 300 328-2 V1.2.1 (2001-12)
Technical requirements for spread-spectrum radio equipment
• EN 301 489-17 V1.2.1 (2002-08)
EMC requirements for spread-spectrum radio equipment.

This device is a 2.4 GHz wireless LAN transceiver, intended for indoor
home and office use in all EU and EFTA member states, except in France
where restrictive use applies.
The use of this radio in France is subject to additional restrictions. You
may only use the radio in French territory when it is set to reduced power.
If the radio is contained in a printer, then the power setting will print out on
the two-key report as either “Normal” or “Reduced (France)”.

  In order to exchange data, two Bluetooth enabled devices

must establish a connection.  Bluetooth software is always run-
ning in the background, ready to respond to connection requests.
One device (known as the 

master 

or the 

client)

 must request a

connection with another.  The second device (the 

slave 

or the

server

) then accepts or rejects the connection.   A Bluetooth en-

abled QL 420 will normally act as a slave, but in theory any Blue-
tooth device can be either a master or a slave.  This miniature
network is sometimes referred to as a “piconet” and can consist
of several Bluetooth enabled devices.

Each Bluetooth QL 420 has a unique Bluetooth Device Address

(BDA) loaded into its QuickLink module when manufactured.
For the most part, communications using the Bluetooth protocol
are initiated and processed without any operator intervention,
much like the IrDA system described previously.
