Calculation of Focus 1 and Global Filters

When RoomPerfect™ calculates the filters the display shows the following, ‘Calculating filters - Please
wait’.

The filter calculation process can be expected to take anywhere between 5 seconds and a minute de-
pending on the specific task.

When RoomPerfect™ has calculated the room correction filters, they are automatically saved. The Focus
filter is saved as setting 1 and Global is saved as setting 9 out of the possible 9 filter settings.

You have now successfully completed a guided set-up and the RoomPerfect™ Advanced Menu is now
available.
