1.5.1 Over Temperature Alert
If the internal temperature of the RS20i reaches a critical level of 50°C or greater, a red flashing
alert indicator will appear.
Figure 10. Over Temperature Alert message
The flashing alert message appears only on the Home screen. The RS20i will remain operational
and the menus can be accessed as usual. The actual circuit board temperatures appear on the
System Info page (Setup > System Info). The alert condition overrides, or temporarily disables
the screensaver mode if it is set. The alert will stop if the temperature cools below 50°C.
Note: This alert message often indicates that there is a problem with proper air flow through
the vent holes on both sides of the RS20i chassis. Check that there is nothing obstructing
these air vents. Be sure that the fan is spinning (you will feel air blowing out of the RS20i
from the fan). If the vents are clear and the fan is spinning, yet the temperature alert does not
stop, call your installer for service.
