ACTIVE frequency window and depress-
ing the frequency transfer button will
cause the ACTIVE frequency to be
placed in blind storage and the STAND-
BY frequency (in blind storage) to be dis-
played in the ACTIVE window display. In
radial mode of operation, the right hand
window of NAV display shows the radial
FROM the station. Figure 16 illustrates
the NAV side of the display in this mode:
When a too weak or invalid VOR sig-
nal is received the display flags as
shown in Figure 17.
Another push of the mode button will
cause the unit to go into the TIMER
mode. See Figure 18. When the unit is
turned on the elapsed timer begins
counting upwards from zero. The timer
can be stopped and reset to zero by
pushing the NAV frequency transfer but-
ton for 2 seconds or more causing the
ET on the display to flash. In this state
the timer can be set as a countdown
timer or the elapsed timer can be restart-
ed. The countdown timer is set by using
the NAV inc/dec knobs to set the desired
time and then pushing the NAV frequen-
cy transfer button to start the timer. The
outer knob selects minutes, the inner
knob in the "in" position selects ten sec-
ond intervals, and the inner knob in the
"out" position selects individual seconds.
After the countdown timer reaches zero,
the counter will begin to count upwards
indefinitely while flashing for the first 15
seconds. Or the elapsed timer can also
be reset to zero and started again after it
has been stopped and reset to zero by
pushing the NAV frequency transfer but-
ton. The Audio Alert, if installed, is then
sounded.
The NAV ACTIVE and STANDBY fre-
quencies are stored in the memory on
power down and return on power up.
When the smaller increment/decre-
ment knob is pushed in, depressing the
NAV TRANSFER button will interchange
the ACTIVE and STANDBY frequencies.
The NAV IDENT knob is active in the
