Jabra BT2020 - Headset - Over-the-ear Instruction Manual page 14

Pairing creates a unique and encrypted link between two Bluetooth devices
and lets them communicate with each other. Bluetooth devices will not work
if the devices have not been paired.
Passkey or PIN is a code that you enter on your Bluetooth enabled device
(e.g. a mobile phone) to pair it with your Jabra BT2020. This makes your
device and the Jabra BT2020 recognize each other and automatically work
together.
Standby mode is when the Jabra BT2020 is passively waiting for a call. When
you 'end' a call on your mobile phone, the headset goes into standby mode.
Dispose of the product
according to local
standards and regulations.
