Do I need to install any new driver software to use the Philips AirBridge ACC4100 with my SpeechMike Premium Air?

Since the AirBridge is fully plug-and-play you don't need to install any new driver software to use your SpeechMike Premium Air with an AirBridge.

Only if a firmware upgrade of the AirBridge is needed users should use the latest SpeechControl 4.2 software
