NOTE 

After entering the calibration mode, 

and after the last button push, if the  

exit procedure, item 6 above, is  

not done within 90 seconds, the 

calibration procedure will cease and  

reset to the last saved setting. 

 

 
 
 

Alternative Aux Switch Options 

 
As noted on page 3, point 3, denergizing the “Oval’s” point 3 will initiate a full retraction of the tabs and indicators.  If point 3 
remains denergized, the “Oval” will remain shut down.  Alternatively, if point 3 is denergized and immediately reenergized, the 
“Oval” will initiate a full tab retraction but will remain on.  This feature will accommodate connecting point 3 through a gearshift 
switch which is open circuit at neutral.  In this case, after the engine is started and put in gear, point 3 would be energized, readying 
the “Oval” for use.  Then, at the end of the trip, when the gearshift is returned to neutral, or even passed through neutral to reverse, the 
“Oval” would initiate full tab retraction and shut down.  This scheme would provide tab retraction upon reaching the docking area 
instead of waiting for engine shutdown.  With some thought, other interesting options for controlling point 3 may come to mind.
