Bluetooth Passkey
The Bluetooth passkey (or PIN) is used to validate two Bluetooth devices to
each other and create a trusted relationship between them. It is used to
prevent unauthorized use of a Bluetooth device by people other than the
owner of the device. The process of creating a trusted relationship between
two Bluetooth devices is called “Pairing” (see next section).
Each ATO Bluetooth headset has a unique passkey, which is stored in its
internal memory. You can find the value of the passkey from the supplied
user registration card. Whether you need to use the passkey during pairing
depends on the kind of Bluetooth device that the headset will be connected to:
1. ATO Mobile Phone Adaptor – If you are using the headset with a mobile
phone that has the ATO Mobile Phone Adaptor that comes with the
Headset installed, you don’t normally need to use the passkey. Please
refer to the ATO Mobile Phone Adaptor user guide for more detailed
information.
2. ATO PC Adaptor – If you are using the headset with a PC that has the
ATO PC Adaptor connected, depending on the configuration of the PC
software, you may be required to enter the passkey on the PC during
pairing. Please refer to the user guide of the ATO PC Adaptor for
detailed information.
3. Bluetooth Mobile Phone or other devices – If you want to use the headset
with a mobile phone or other devices with Bluetooth capability, you are
usually required to enter the passkey on that device during pairing.
Please refer to the user guide of the mobile phone for the specific
operation.
