Sensor Range Requires Manual Adjustment.
Sensor Range is measured in units from 1 to 5, with 1 being closest to the faucet and 5 being farthest from the faucet. The factory default
Sensor Range is 3.
A. To determine what the current Sensor Range setting is, press the red “Sensor” button on the upper right hand corner of the Optima Control
Box for 1 second. Five seconds after pressing the button, the green LED beside it will blink to indicate the Sensor Range setting. For
example, if it is set at 2, the green LED will blink 2 times.
B. To adjust the Sensor Range, press and hold the red “Sensor” button for three seconds and release once the green LED comes on to indicate
that you are in Sensor Range adjustment mode. Then press the “Sensor” button one second at a time for however many times you wish to
increase the range. For example, if the Sensor Range is set at 2 and you wish to increase it to 4, press the “Sensor” button two times for one
second each time..
C. If you wish to decrease the Sensor Range, follow the same procedure to enter into Sensor Range adjustment mode, and then press
the “Sensor” button one second at a time. The button is designed to go up to 5 units and then back down to 1 unit. For example, if the
Sensor Range is set at 4 and you wish to decrease it to 2, press the “Sensor” button three times for one second each time.
D. To conform your changes, wait 5 seconds and then press the red “Sensor” button on the upper right hand corner of the Optima Control Box
