BENDIXKing KLN 90B Pilot's Manual page 27

The KLN 90B needs to have the correct time, date,
and position to be able to determine which satellites
should be in view. This information is stored in the
battery backed memory of the KLN 90B so it is not
normally required to update it. If the KLN 90B has the
correct time, date, and position, then the time to first
fix will usually be just a couple of minutes or less. If
this information is not correct, then the KLN 90B will
start to look for any satellites. Eventually, the KLN
90B will find enough satellites to determine the posi-
tion of the aircraft. This process can take as long as
12 minutes but will normally be around 6 minutes. It is
possible for you to update this information manually
which will allow the KLN 90B to reach a NAV ready
status much faster. To set the time and date follow
steps 6 and 7. If the date and time are correct, or
acquisition time is not important, then skip to step 8.
6. If the date is incorrect, rotate the right outer knob
counterclockwise until the cursor is over the entire
date field (figure 3-6). Rotate the right inner knob
until the correct day of the month is displayed (figure
3-7). Then, rotate the right outer knob one step
clockwise to place the flashing part of the cursor over
the month field (figure 3-8). Rotate the right inner
knob to display the correct month (figure 3-9). Rotate
the right outer knob one step clockwise again and
use the right inner knob to select the first digit of the
correct year (Figure 3-10). Next, rotate the right outer
knob one more step clockwise and then use the right
inner knob to select the second digit of the year
(figure 3-11). When the date is correct, press E.
7. If it is necessary to reset the time, use the right outer
knob to position the cursor over the time zone field
(figure 3-12). Use the right inner knob to select the
desired time zone (figure 3-13). The following are the
time zones which the KLN 90B is capable of
displaying:
