Once the barometric pressure setting has been entered, press the DTA switch to
make it operational, such that the ENT annunciation is extinguished and the
BARO annunciation stops flashing.

To change the barometric setting at times other than immediately following
power-up, press the DTA switch such that ENT is annunciated.  Then press the
BAR switch, such that the BARO annunciation appears flashing.  The setting can
then be changed using the Modifier Knob as described above.  Once the
barometric pressure setting has been entered, press the DTA switch again to
make it operational, such that the ENT annunciation is extinguished and the
BARO annunciation stops flashing.

The Selector / Alerter barometric pressure setting will automatically change to
29.9 inHg or 1013 mb, above an altitude of 18,000 feet (FL 180).  Even so, the
last setting will continue to appear unchanged.  Prior to descending below
FL 180, change the barometric pressure setting as required for the new area.
Once subsequently at or below FL 180, the Selector / Alerter will automatically
reference this setting.

3.1.3 Altitude (ALT) Select

Press the DTA switch (more than once if necessary, depending on the current
configuration of the Selector / Alerter), such that ENT and ALT are both annunciated,
and the SEL annunciation is flashing.  The selected altitude is now ready to be
entered.  Rotate the Modifier Knob clockwise (CW) to increase the altitude
selection, or counter-clockwise (CCW) to decrease the selection.  When the
Modifier Knob is pushed-in, each detent changes the selection by 1000 FT.
When the Modifier Knob is pulled-out, each detent changes the selection by
100 FT.

Once the selected altitude has been entered, press the DTA switch to make it
operational, such that the ENT annunciation is extinguished and the SEL
annunciation stops flashing.

To display the true altitude, press the ALT switch.  The SEL annunciation will
extinguish as a result.  To go back and display the selected altitude, press the
ALT switch again.  The SEL annunciation will re-appear as a result.

If the newly selected vertical speed is not compatible with the selected altitude,
then the latter will flash for 5 seconds to alert the pilot accordingly.  

There will be

no automatic change to the selected altitude.

Suppose that the aircraft is at an initial altitude of 5,000 FT, with a selected
vertical speed of 100 FPM climbing and a selected altitude of 6,000 FT.  If the
selected vertical speed is subsequently changed to 100 FPM descending, then
the selected altitude (6.0 on display) will flash for 5 seconds.

Suppose that the aircraft is at an initial altitude of 6,000 FT, with a selected
vertical speed of 100 FPM descending and a selected altitude of 5,000 FT.  If the
selected vertical speed is subsequently changed to 100 FPM climbing, then the
selected altitude (5.0 on display) will flash for 5 seconds.
