Polycom B189 TouchScreen calibration

[salva5]

How do we adjust the touchscreen calibration on Polycom B189 conference phones?
We want to adjust the sensitivity & responsiveness of the touchscreen.
We have B189 H.323 polycoms , firmware: App File R1.0.1.08 , Kernel V13.R133.tar
We cannot find calibration settings from the CRAFT menus.
Please advise.

FYI - the B189 is not a "Polycom" device.

Ok, Thanks. Force of habit in using the name polycom for conference phone...
My query is:
