Philips Speech Mike Query

CRIS version 2.12.13
Philips Speech mike Premium 3500.

We have several speechmikes when in use with CRIS that turn on when placed horizontal and then turn off when brought upright. When in the upright position the button can be pressed and then it turns. Like a deadmans switch.

The Phillips software ensures me that the motion control is turned off

This issue has only just started an only effecting a handful of workstations that I am aware of.

Has anyone else experienced this problem?
