Dear Melvin,

 

Thanks very much for this.

 

We have been piloting the use of a new mobile device - Motion C5 MCA - in a hospital serting - actually an ICU. The topic I raised was one possible explanation of some earlier problems we encountered. We now think those problems are attributable to other factors which have since been resolved. But we are keeping this under review and will take note of these references, for which many thanks.

 

kind regards

 

Colin
