Bluetooth wireless technology facilitates instant
connections, which are maintained even when the
devices are not in the line of sight. Enhanced audio
quality voice transmission is provided under
adverse conditions, making it possible to use a
headset connection to the phone at all times.
Using Bluetooth wireless technology
in Z520
True wireless connection
Connect without cables to headsets, car handsfree
equipment, computers/PDAs, digital still cameras
and other devices.
Simultaneous Bluetooth connections
The Bluetooth profile lets the user connect to sev-
eral units simultaneously. For example, the user
can talk on the phone using a Bluetooth headset
and send an image to another phone at the same
time. It is also possible to let several players join a
Bluetooth supported game. The Z520 supports
Bluetooth specification 2.0.
Up to 16 paired devices
The phone identifies and maintains up to 16 paired
devices which are displayed in a list.
Radio link
No line of sight required; the phone can remain in a
briefcase or in a pocket (whereas infrared requires
line of sight).
Secure and user-friendly
Data connection with a Bluetooth computer/laptop
or PDA turns the phone into a modem for connect-
ing to the Internet and for data transfer.
Synchronization
Fast synchronization, even without line of sight, of
calendar, notes and phone book with computer/
laptop.
Range
The range is up to 10 meters. When searching,
devices in close range are discovered first.
Business cards
Quick exchange of business cards, notes and cal-
endar events with other phones and devices.
Imaging and music
Music files, images and video clips can be
exchanged with another mobile phone, computer
or laptop. Images and video clips can also be
exchanged with a digital still camera.
Audio quality
The phone uses an algorithm that repairs lost audio
packets. When needed, a new packet is inserted
with content based on previous packets. This, in
conjunction with re-transmissions, the high sensi-
tivity and high output power radio will enhance the
audio quality compared to a standard Bluetooth
device.
File sharing
By using the Server role of the File Transfer Profile,
the phone enables the user to use a computer to
manage content files that reside in the phones file
system. Most computer Bluetooth applications
provide an explorer like user interface for the file
transfer service. When connecting to the phone,
the computer application will show some of the
folders that the user can find under the File Man-
ager icon on the phones standby screen, i.e. Pic-
tures, Sounds, Videos, Themes and Others. The
content in the Games and Applications folder is not
exposed in the file transfer server. Opening one of
these folders will show a list of files related to that
folder, e.g. images in the Pictures folder. Using the
computer application the user can now: retrieve
files from phone to computer, delete files from the
phone and transfer files from the computer to the
phone using the normal drag and drop mecha-
nisms provided by the computer.
Media viewing
The phone can send images and sounds to a
media viewer device, for example the Bluetooth
media viewer MMV-100 or the Bluetooth Media
Center MMV-200. This allows the user to conven-
iently run a slide show on the TV showing a set of
phone camera pictures for family and friends. After
selecting an image in the Pictures folder under the
File manager icon, the user can select the Remote
screen option under More. The phone will then
