Activate the PW Display
To activate the PW spectral display, follow these steps:
1. Press PW once. The 2D sector is live and the Trackball is assigned to the PW
cursor line.
2. Position the cursor to the desired portion of the image, and press PW a sec-
ond time. This freezes the
2D image and activates the PW spectral display.
3. Pressing PW again toggles between the active spectrum and the real-time
sector image. You may also reposition the
PW sample while the 2D image is
frozen. The cursor line in the
2D image will move, but the 2D image remains
frozen.

They are controlled by the Main knob. Press the Main knob to toggle between
the options.
Volume Increases or decreases the amplification of the audio signal sent to
the system speaker.
PW Gain Turn the knob clockwise to increase the amplification of the Dop-
pler signal. Turn counterclockwise to decrease.
