Software Update 5.53

This update has now been superseded by update 5.54:

A new software update has been released for most IHS programs. For the Duet platform, this version enables the display of both EEG channels simultaneously in the EEG panel and includes the ability to show and hide the contralateral responses. For all platforms it now allows the recalculation of Fsp and Fmp and includes new features for P300 acquisition, and adds general software improvements. See our New Features video on our YouTube channel, here:
