Maintenance
Filter
The filter should be checked and cleaned periodically to prevent system
overheating. To clean the filter, remove the filter cover, then remove debris
or dirt from the filter. Replace the filter and the cover.
The touchscreen isn’t
responding to your touch.
Power off, wait a few seconds and
power on. When the Envizio Plus
start-up screen displays, touch below
the Envizio Plus logo to re-calibrate
the touchscreen. Follow the instruc-
tions on the screen and touch the
calibration mark everywhere it
appears on the screen. When the
system is finished with the
re-calibration, the Home screen
displays and the system is ready for
operation.
The Envizio Plus does not start
when powered on.
Ensure that you have +12 VDC to the
Envizio Plus system. If the Envizio
Plus turns on, but does not start-up
properly and has a partially blank
screen, you will need to ensure that
voltage to the Envizio Plus system is
at least +9.5 VDC and no greater than
+15 VDC.
