1. Turn potentiometer P3 (10, Fig. 7-41) until the LED Tank empty
(1, Fig. 7-41) just begins to light up.
2. Turn back to the switching point when the LED Tank empty just goes off.
3. From the switching point, turn half of a revolution more to the left.
NOTE: The closer the setting is to the switching point, the higher the
sensitivity.
4. Turn potentiometer P4 (9, Fig. 7-41) until all of the LEDs (2 to 5,
