Feedback Setup:

1. Switch off the 977HL and connect the feedback sensor bar using the 3.5mm jack

plug.

2. Switch on the 977HL. The LCD display will now display an additional
bargraph that represents the voltage being detected by the sensor bar.

3. Use the front panel controls to set the correct output voltage (page 9) and the rate
(page 11).

4. The 977HL will now continuously adjust the balance of the output to attain the most
accurate neutralisation of charge possible.
