Pairing
What is “Pairing?”
Pairing is a Bluetooth function that enables Bluetooth devices to remain permanently linked to another.
What “Pairing” means in terms of security?
As mentioned, Pairing allows devices to permanently link with each other. The pass key authentication will also
be perpetuated in Pairing, meaning that devices will not ask for a pass key once they are paired. Paired devices
will remain linked, even if other paired devices are turned off. Once a paired device turns back on, it is ready to be
used and service requests will not ask for the pass key again. The built-in 128 bit security encryption of
Bluetooth assures the privacy of your paired devices. Note: If devices are unpaired, it is necessary to enter a pass
key each time a service request is made from or to another Bluetooth device.

Pairing Devices
Right-click on the Bluetooth device and select
on “Pair device”.
Enter a Pass Key when asked.
Note: The Pass Key on both devices must be
the same!
Example: If Device 1 tries to pair with Device
2, Device 1 will prompt for a Pass Key. Enter
any Pass Key. Device 2 will then ask for a
Pass Key. Enter the Pass Key, which has
been set for Device 1. Done!
The device is now paired with your computer.
