CALIBRATION
1. After installation, remove cover from cable reel. With the boom full retracted and boom stops
disengaged (if applicable), adjust the length potentiometer by turning the screw in the center of the
large nylon gear on the length sensor counter-clockwise until a soft stop occurs, and reinstall the cover
on the reel.
The length should be calibrated to be about 0.1 feet (or 0.05m) accurate for both retraced and extended
lengths.
2. The angle sensor must be level. Remove cover from reel. Adjust the level of the angle sensor by
loosening the socket head cap screws and aligning the top of the angle sensor until parallel with the
boom. Reinstall the cover on the reel.
