CONTROL page only). See the VHF Naviga-
tion System section discussed earlier for more
information on AUTO vs MANual tuning.
Figure 16-141. CDU NAV Page
The lower section of this display contains the
NAV PRESETS. This section operates exactly
like the COM PRESETS discussed earlier.
ATC CONTROL Page
The ATC CONTROL page is selected by
pressing the ATC line select key (the scratch-
pad must be empty) (Figure 16-142). This page
allows for transponder code entry, altitude re-
porting selection, testing the transponder and
optionally entering a Flight ID. With the alti-
tude reporting turned ON the automatically
selected ADC will be displayed along with its
corrected barometric pressure. Should an
ADC fail the opposite ADC will automatically
be selected. Additionally, the selected code is
always identical between the RTU and CDU.
The Flight ID field should contain only the
ATC given identifier or the aircraft registra-
tion as appropriate.
To turn the transponder ON or OFF and to se-
lect STBY, a separate switch on the reversion-
ary panel must be moved. See the ATC
Transponder section earlier in this chapter.

ADF CONTROL Page
The ADF control page is selected by pressing
the ADF line select key (the scratchpad must
be empty) (Figure 16-143). From here the
ADF can be tuned, Beat Frequency Oscillator
(BFO) can be turned ON or OFF, the mode
selected, or the ADF can be tested. The BFO
selection should only be used for an NDB that
cannot produce a typical Morse code identi-
fier. The ANT mode provides only an audio
output and does not create bearing-to-the-sta-
tion signals. The bearing pointer will “park” at
the 3 o’clock position. Both of these selections
are abnormal and the CDU will annunciate on
the main level TUNe page when chosen.
The lower section of the display contains the
ADF PRESETS display. Just like the COM
and NAV radios this can contain up to 20
preset ADF frequencies. This section oper-
ates exactly like the COM PRESETS dis-
cussed
