RECCOMENDATION
Always make a note of the position of the ‘Free play’ or ‘Adjust A’ potentiometer before
adjusting its position. Because these potentiometers are very sensitive we advise to
measure its setting before making changes using a Voltmeter as shown in the figure
below.
It is advised to measure voltage for both potentiometers and
write down its settings, before making any changes.
By doing this, you can always go back to these settings.
