my best GUESS.......
SLV=SLaVe (slave), FREE means what it say, "FREE"
CW= ClockWise, CCW=Counter-ClockWise
So for a gyro instrument of some type, probably a RMI or HSI?????
Do you want it (whatever instrument it is linked to) to show the same heading as the heading indicator, if so, then "slave" position. For independent operation, the "free" position.
To align the instrument (in FREE mode?) to the heading that you want, use the CW or CCW switch to rotate.
Janitrol gas/fuel powered heater shows red if overheat, can only be reset on the ground. Not really that important, but why did it overheat.......
Yellow may just show low suction pressure, so gyro may still work, but not optimum?
