Fan/Heat Monitor Alarm
Symptom
Explanation and Possible Solutions
Fan/Heat Monitor Alarm
Consult the Environment tab on the Properties dialog 
for readings of the fan speeds and unit temperature. 
Compare these readings to those recorded during 
normal operation to determine the nature of the 
problem. 
Verify that nothing has become inserted in the fan or 
ventilation holes which could restrict the fan operation 
or airflow. In a normal working environment i.e. setup 
in accordance with the 
the
unit is able to function correctly with a fan or fans 
disabled. 
If the condition persists then it could indicate that the 
temperature is above the level required for reliable 
operation and the unit should be returned to Thales for 
investigation/Repair.
