Problem

A Focus 5^th generation user is attempting to pair with an IOS device but during pairing either a message ‘Unsupported device’ or pairing fails for another reason. 

Resolution

1. Consider if it is possible that the Focus may already have been paired with the device. Since the Focus V has 4 slots for establishing Bluetooth connections, an existing connection pairing may already be available.  Check pairing slots.
   
2. If there has previously been an unsuccessful pairing between a Focus and IOS device the IOS device may have stored and held onto incomplete pairing information that prevents it from establishing a clean pairing.
