This is why different version numbers are displayed on the website (e.g. 3.71/2.65). When running a firmware upgrade, Philips software version 4.3 or later will always pick proper firmware components for the currently connected device.

To run firmware upgrades with this 4-in-1 firmware you need to use SpeechControl version 4.3 (or later), SpeechMike SDK 4.3 (or later) or PRDM 4.3 (or later).

NOTE: This firmware CAN NOT be used for upgrades of the SpeechMike Premium Touch SMP37xx/SMP38xx
