Questions answered in these manuals
How many height sensors does the UC4+ system use?
Normally three height sensors are used, but the system can be configured with up to six sensors.
How do I switch between Automatic and Manual mode?
Toggle the "AUTO" switch on the control panel; in Manual mode you can use the boom control switches, and in Automatic mode the system controls boom height automatically.
How can I adjust the target boom height?
Use the +/- switch while in AUTO mode, or momentarily press the sprayer’s main lift control switch; each press changes the target height by one inch.
