II Morrow Inc. 920 - Manual (Page 45)

WGS 1984 is the most recent datum and
should normally be used unless you plan to
navigate with a chart that was created using an
older datum. In this case, you may wish to
select the datum used to create the chart.
The simulator mode allows you to practice
navigating without actually traveling. All
options are available in simulator mode. You
can select the speed of simulated travel from 0
to 900 units. After simulator use, the receiver
will return to the previously used non-
simulator operation mode the next time you
switch the receiver on.
Time and Place
Use this option to enter your present position
and set UTC and local times as Section B
describes in “Entering a Seed Position.” It is
necessary to enter the time and place the first
time the receiver is switched on. It is also
necessary to enter this information if the
receiver is switched off and moved a distance
of several hundred miles or more.
