An alternative method, (instead of performing steps 3, 4 & 5 above) is<br />
to leave the jumper in its original position; and to press the ’On’ button<br />
while carefully shorting out the two pins of LK1 (furthest from the potentiometer<br />
connector) with a small electrical screwdriver.<br />
6. Insert the Calibration plate (90-034-01) with its inserts set at ‘225’<br />
and move the deflector up to the plate.<br />
7. Press the ‘Micro’ button when the display shows ‘225’, - the display will<br />
now change to read 160.<br />
8. Insert the Calibration plate with its inserts set at ‘160’ and move the deflector<br />

read ‘105 ‘<br />
