Operating Range: Up to 65 feet depending on target reflectivity:

1/2” reflective tape (T-5) @3600 RPM: up to 65 ft. (19.8 m) or up to 75° from target

White/Black contrast @3600 RPM:	up to 3 ft. (91 cm) or up to 45°
	from target
Black mark on dental drill:	up to 4 in. (10 cm) at over
	260,000 RPM

or comes on solid. If you can’t get a good setting, change the gain. Press and release the Learn/Gain button (6) to change the gain of the input amplifier. Each time the button is pressed, the gain is changed. The Auto/Gain LED (3) will blink to show what gain has been selected. If the button is held down, the gain will increase automatically after each LED ‘blink’ pattern. Refer to Table 2. The larger the gain, the weaker the signal being picked-up. Using a large gain for a strong signal is not recommended since the input will saturate.

7.0 ADVANCED FEATURE (TARGET POLARITY)

The input circuitry can be set to optimally work with two different target types: a reflective (white, shiny) target on a mostly non-reflective (black, dull) background or a non-reflective (black, dull) target or a mostly reflective (white, shiny) background. These will be referred to as a white target or a black target. When the unit is first turned on, the On Target LED (1) will indicate which target type the sensor is set up for. While the Laser On LED (2) is blinking, the On Target LED will be on for a white target or off for a black target. The unit will still work when set up for the “wrong” target type, but it won’t have as great a range. When set for a white target, the unit triggers on the black to white transition. When set for a black target, the unit triggers on the white to black transition.
