CAUTION
Battery stabilization requirements
When increasing or decreasing the float voltage on a
working system with batteries connected, always proceed
very slowly. Only turn the float potentiometer 1/4 turn at any
one time then allow the batteries to stabilize before
adjusting the FLT potentiometer again. The batteries
require a period of time to stabilize to the new voltage and
current levels.
