Figure 11. Over Temperature Alert message
The alert message appears only on the Home screen. The AP20 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 AP20 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 AP20 from the
fan). If the vents are clear and the fan is spinning, yet the temperature alert does not stop, call
Datasat Technical Service or your technician.
