The local time zone (LCL) is selected on the SET 2 page, and is
defined to be a certain time offset from Zulu (UTC).
Once you have selected the desired time zone, position the cur-
sor over the entire time field and select the correct hour with the
right inner knob (figure 3-12).
Since 24 hour time is used, be
sure to add 12 if the time is after
1:00 P.M. (2:30 P.M. becomes
1430). Now move the cursor to
the tens of minutes position and
select the desired value, and
repeat this process for the last
digit of the time field. When the
correct time has been entered
(figure 3-13), press
F
to start
the clock running. Don’t worry
that you can’t update the
seconds. The KLN 35A system
time will automatically be correct-
ed very precisely once a satellite is received.

To aid the GPS receiver in acquiring your position, it is vital that it
have a reasonable idea of where you are, and the Initialization
page is where you have the chance to set this initial position.
Check to see if the displayed initial position is where you actually
are. This latitude/longitude is the last known position before the
power was shut down the last time. Unless the unit has been
moved since its last use, this position should be correct. On the
right side of the screen will be the identifier of the nearest airport
in the data base, with a radial and distance from that airport. If
you need to change the initial position to—let’s say—John F.
Kennedy International (KJFK), move the cursor to the WPT: field
and use the right inner knob to
select a K as the first character of
the identifier (figure 3-14). Move
the cursor to the right one char-
acter and select a J and then
right again to select an F. The
final K should be filled in by the
data base (figure 3-15). When
you press
F
, the latitude and
longitude fields will change to
