Determine if the image frequency for the VOR/ILS Nav falls within the range of
the NPX136D unit. If so, select two sets of frequencies that will cause the
NPX136D to be set as close as possible to the image frequency. Choose one
set in the localizer frequency range, and one in the VOR frequency range.
Record these values in the spaces provided in the following chart. Modulate the
NPX136D transmitter on the following frequencies for at least 20 seconds. Listen for
any noise or detected audio signals on the receiver audio; look for any movement of flags
or needles on the navigation display.
