In auto-To mode, the CDI displays with the deviation bar in the center position and the OBS showing a direct course to the selected station. The “TO” annunciator will show. When the receiver stabilizes the CDI will go back to normal operation and show any course deviation.
) Localizer (LOC) Mode. When a localizer frequency is the set as the active frequency and a valid navigation signal is being received the KX 125 shows localizer information. The CDI displays and LOC shows in the bottom half of the center display. The “FLAG” indicator shows in the bottom right of the display when no valid signals are being received in LOC mode.
The KX 125 has these controls:
) OFF/PULL TEST switch. Turn the switch fully counter-clockwise to set the receiver to OFF. Turn the switch clockwise to set the receiver on and to set the volume to the desired level. The KX 125 has automatic squelch. Pull the switch out to cancel the squelch and test the volume level. Push the knob in to set the automatic squelch.
) COM Frequency selector. The COM frequency selector has an inner knob and an outer knob. Turn the outer knob clockwise to increase the frequency in 1 MHZ increments. Turn the outer knob counter-clockwise to decrease the frequency in 1 MHZ increments. Turn the inner knob clockwise to increase the frequency in 50 kHz increments. Turn the inner knob counter-clockwise to decrease the frequency in 50 kHz increments. Pull the inner knob out to set 25 kHz increments.
) MODE Button. Momentarily press the mode selector button to change the NAV mode when a valid VOR frequency is set as the active frequency. The mode will rotate through CDI-BRG-RAD in order. Changing the active or standby frequency will not change the mode unless a localizer frequency is set as the active frequency.
Press and hold the MODE button for at least two seconds when a valid VOR frequency is selected as the active frequency to set the NAV receiver to Auto-To mode. You can enter Auto-TO mode directly from any mode.
) PULL IDENT switch. Pull the switch out to activate the NAV identification (Ident). Turn the switch clockwise to increase voice and ident tone. Turn the switch counter-clockwise to decrease the volume. Push the switch in to mute the ident and voice tones.
