2.6 Start Procedures for the F24-12S, F24-12D: 
1.  If the red STOP knob is pushed in, turn it clockwise about 45 degrees to reset it and allow 
it to pop up. This knob must be in the up position in order to operate the transmitter. 
2.  Put the green key into its slot in the front of the transmitter, next to the red STOP knob. 
3.  Turn the green key clockwise. The green key must go past the ON position detent, to the 
START position. Then release it and it will spring back to the ON position. 
4.  Use the pushbuttons to control the equipment. The model F24-12D uses two-step 
pushbuttons; pressing them to the first detent will activate the equipment at the slow 
speed, and pressing them fully will activate the equipment at the fast speed. 
5.  Press the red STOP knob or turn the green key to OFF to stop movement immediately 
and drop out the mainline contactor. 
6.  Turn the green key to OFF and remove it whenever the transmitter is not in use to prevent 
unintentional operation. 
7.  The F24-12S and F24-12D models have an extra relay in the receiver, labeled R0. 
Turning the green key to START after the equipment has already been started will close 
this relay. This relay will not engage the first time the key is turned to START when 
starting up the equipment. See section 5.3 for detailed information on this option.
