How to change the polar pattern.
Locate the pattern switch on the PSU. Use this switch to operate the

intermediate positions. The center position is the Cardioid setting.
As you turn from position to position it will take a few seconds for the
polarization voltage to settle and achieve the desired polar pattern.
