How to access Logitech system application / CollabOS:
If you are using Logitech Tap, Tap IP or Tap Scheduler, follow your service provider/platform's instructions for reaching system/device settings. This will bring you to the Logitech Settings application in CollabOS.
When using Rally Bar, Rally Bar Mini or RoomMate without a Logitech Tap Controller, you can access the Logitech Settings using the included remote control. On the Rally Bar, Rally Bar Mini, or RoomMate remote control, press and hold the hookswitch (end call) button for 5 seconds. The Logitech settings application will then be displayed on the TV screen and can be navigated using the remote control.
