®
TECHNOLOGY
What is Bluetooth
®
wireless
technology?
Bluetooth
®
wireless technology is a radio
technology that connects devices, such as mobile
phones and headsets, without wires or cords
over a short distance of approximately 10 meters
(
Approx. 33 feet
)
. Get more information at www.

What is Bluetooth
®
wireless
profiles?
Bluetooth
®
wireless profiles are the different
ways that
Bluetooth
®
devices communicate with
other devices.
Bluetooth
®
phones support either
the headset profile
(
HSP
)
, the hands-free profile
(
HFP
)
or both. In order to support a certain profile,
a phone manufacturer must implement certain
mandatory features within the phone’s software.
The followings are the currently supported profiles
for BLT573.
Headset Profile
(
HSP
)
This is the most commonly used profile, providing
minimal controls including the ability to ring,
answer a call, hangs up and adjusts the volume.
What is pairing?
Bluetooth
®
devices will not work if the devices
have not been paired.
With a mobile phone featuring
Bluetooth
®
technology, you must ‘
pair’ the BLT573 with the
phone before you use it for the first time.
‘Pairing’ creates a unique wireless link between
the phone with
Bluetooth
®
wireless technology
and your BLT573 eliminating the need to repeat
the pairing process during future use.
What is passkey?
Passkey or PIN is a code that you enter on your
mobile phone to pair it with the
Bluetooth
®
receiver
unit. This makes your phone and the
Bluetooth
®
receiver unit recognize each other and automatically
work together
.
The
Bluetooth
®
wireless function in your
phone has to be turned on to establish
automatic connection.
Object Push Profile
(
OPP
)
A basic profile for sending “objects”, such as
contacts and virtual business cards. It is called
push because the transfers are always instigated
by the sender
(
Client
)
, not the receiver
(
Server
)
.
