4.3.1.3.  FAN Mode: 
The operating temperature of the repeater may not exceed 100°C 
[212°F].  Depending  on  environmental  conditions,  the  internal 
FAN will help the heat-sync to keep temperature under the limit, 
extending the repeater performance. 
Press on the arrow to list down the possible values:

Auto:  The  FAN  will  work  controlled  by  repeater  temperature 
limits  programed  on  the  alignment  procedure  (See  ST-9116 
Service manual – Alignment). 
On: The FAN will remains all time on. This option will demand 
more  quiescent  current  than  required  becoming  inefficient.  It 
should be useful for high temperature environments. 
Off: The FAN never will blow. 
4.3.1.4.  Set Low Power on Voltage: 
If the DC power voltage drops under the limit programmed on this 
field, then the repeater will jump to the low RF power programed for 
the  repeater  to  save  battery.  This  feature  is  especially  useful  for 
solar-powered sites or when the site works on power back up during 
a possible AC failure.
