Determine if the image frequency for the VOR/ILS Nav falls within the range of the TFM-500. If
so, select two sets of frequencies that will cause the TFM-500 to be set as close as possible to
the image frequency. Chose one set in the localizer frequency range and the other in the VOR
frequency range. Record those values in the spaces provided in the following chart. Modulate the
TFM-500 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 moment of flags or needles on the
navigation display.
