To validate these twoBluetooth devices to each other and create a trusted relationship between them, aBluetooth passkey (or PIN) is required. The default passkey stored in the BT-868internal memory is [1234]. You are usually required to enter the passkey onthat device during pairing.The pairing only needs to be done once. You do not need to pair it again until youwant to use it with another device. Afterwards, every time you switch on yourHeadset, it will automatically connect to your mobile phone. Please note,however, Nokia Bluetooth mobile phones required you to reconnect to it manually.
