2. Select function required on slide switch.
3. Press and hold RED 'ON' button.
4. Aim light beam onto reflective marker on shaft.
5. Ensure GREEN LED on target light is on steadily.
Note: This LED flashes at a rate directly related to the speed of the pulses being received from the
refective marker, therefore at low speeds this will be a slow rate, at higher speeds the LED will appear
to glow continuously, if the light flickers or goes out, then the light beam is not being held steadily on
the target.
