IdentifyingtheBluetoothheadset
An individual identification code known as a “PIN code” is assigned to Bluetooth devices 
such as a headset. The PIN code allows mutual identification with paired devices to be 
carried out and recorded when initially when using a Bluetooth terminal device. This 
is known as “pairing”. Through pairing, interference and improper interception can be 
prevented.
Pairing is also carried out initially when communicating wirelessly with this radio using a 
Bluetooth headset.
Tip
The PIN code for the Yaesu Bluetooth headset “BH-2A” is 6111. Check the PIN code in the operating 
manual of the product when using Bluetooth headsets from other companies.
