Operation
a) Making a link (pairing)

With some mobile phones it may be necessary after the pairing process to conrm
the link between your mobile phone and the product.
This is normally necessary if you already have at least one other Bluetooth device
registered to the mobile phone or if the mobile phone is connected to another device

The link will disconnect if the product or paired Bluetooth device is turned off
or removed from range. When the respective device is turned back on or when

automatically restored.
