Angle adjustment
Fully retract the boom and lower the angle to zero degrees using a angle finder
to
determine
zero degrees.Remove the cover of the cable reel and check the +12.00vdc (Typically the voltage
is about 11.9- 13.5vdc) supply voltage (Brown wire) and the ground wire (white wire).
If it is not correct loosen the three mounting screws with a flat tip screwdriver and adjust the pot
until the angle indicates zero degrees on the display. Tighten the screws and check it at other
angles for accuracy.

Troubleshooting Manual
Check the voltage output of the length pot is approximately .250vdc ( wire), (tolerance of .246 to
.254)with fully retracted boom, if not adjust the length gear assembly until it is. Check the length
indication on the display. If it is correct , extend the boom and check the fully extended length.
The Brown wire (+12vdc supply voltage) and White wire (Ground) used for the angle is the same
supply voltage and ground for the length.
