Introduction to Bluetooth Wireless Technology
Bluetooth is a short- range wireless communication technology. It allows wireless connections between
Bluetooth devices such as cellular phones, personal digital assistants (PDA), desktop and notebooks
computers, input-output devices (mouse, keyboards, printers), home appliances. Bluetooth refers to a
worldwide standard designed to operate in the internationally recognized ISM (Industrial Scientific and
Medical) frequency band. Within the ISM band (2.4Ghz – 2.48Ghz) Bluetooth transmissions hop
between 79 separate frequencies 1,600 times every second, and with a communication range of about
10 meters (class II).
Bluetooth Headset
The Bluetooth Headset is a Bluetooth device developed with the latest Bluetooth technology, which can
connect to other Bluetooth devices such as mobile phone, desktop or notebook computer, PDA (with
audio gateway profile supported) wirelessly within a range of 10 meters.

About Pairing
What is Pairing?
Pairing is a process of associating Bluetooth devices with each other. It will establish a permanent
security link between the devices and enable quick access to the services provided without the need
to enter passkeys.
Bluetooth Passkey
Each headset has a default passkey 1234 for pairing, which is stored in its internal memory. You are
usually required to enter the passkey 1234 in a pairing process with a Bluetooth mobile phone or other
devices, however it depends on the kind of Bluetooth device that the headset is connected to. Please
refer to the users’ manual of the devices for the specific operation.
Paired devices remain paired even when:
One of the devices is not powered on.
A service connection is interrupted or the service stopped.
One or both devices are rebooted.
