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
The Bluetooth Stereo Headset has a default passkey 1234 for pairing, which is stored in its internal
memory. Usually users are 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 stereo
headset is connected to. Please refer to the users’ manual of the devices for the specific operation.
Note!
The paired devices remain paired even when both of the devices are powered off, or when a service
connection is interrupted or stopped.
