Software Setup
Overview
The software setup allows for calibrating and/or selecting options for sensor type, tank
shape, and alarm type. Options are displayed sequentially every 8 seconds. Blinking lights
represent selectable options and solid lights represent selected options. Select options by
touching the pad. If you make a mistake, wait for the sequence to complete and try again.
Calibration must be set for both empty and full tanks. Settings are saved when power is off.
