Archer III - Starting and Carb Ice Detector

From an Archer III POH, Section 7

7.39 *CARBURETOR ICE DETECTION SYSTEM
A carburetor ice detection system is available as optional equipment.
The system consists of a control box mounted on the instrument panel, a
probe sensor mounted in the carburetor and a red warning light to indicate the
presence of ice in the carburetor. If ice is present apply full carburetor heat.
Refer to Carburetor Icing, Section 3, Emergency Procedures. To adjust the
system for critical ice detection, first turn on the airplanes master switch and
then turn on the ice detection unit. Turn the sensitivity knob fully
counterclockwise causing the carb. ice light to come on. Now rotate the
sensitivity knob back (clockwise) until the ice light just goes out. This
establishes the critical setting.
WARNING
This instrument is approved as optional
equipment only and Flight Operations should not
be predicated on its use.
 
Interesting, thanks for passing that along from the POH. I swear when I looked through it I could not find it, oh well!
