Cisco TelePresence System EX90
Contents Introduction
Administrator Settings—EMC Resilience Mode
If the Touch controller is used in environments with
considerable amounts of electromagnetic noise
present, you may experience an appearance of false
signals—as if someone tapped the Touch controller
when nobody obviously did so.
To cope with this you may set the EMC Resilience
Mode to On. You must then tap and hold for a little
while, rather than just tap, in order to make the system
aware of your tapping. This will avoid the appearance
of false signals.
