For users who are using the mobile control app on a desktop PC or laptop, it is advisable to switch off the virutal keyboard to avoid having to confirm flow rate or wavelength changes twice with the ’’Apply’’ button. The virtual keyboard can be switched off via System Settings > Preferences > Switch off ’’Show virtual keyboard’’. Please do not switch off the virtual keyboard, if you are using a tablet PC, as the Pop-up keyboard of your tablet will be switched off for all tablet applications.
