it
does, your local time and possibly date
display
will probably be
wrong,
Use the method shown above to setthe time and date to their
proper local
settings.
Oncethis is
done,
an internal clockwill
keepthecorrecttime, even
when the unit is turned off. The GPS
system updates this clock
when the
unit is locked on to the satellites.
POSITION/NAVIGATION DISPLAYS
The
UltraNav II has a
position screen, navigation screen, plotter, steering
indicator, and a satellite information screen. These displays were de-
signed to show the most
important data. However, you can customize all
of them (except the satellite position screen) to some extent through the
"Change Display"
feature on the first GPS menu screen. (There are other
screens that can be customized by using
the Windows feature. See the
• Windows section for more detail.) To customize these screens, see the
'Customize" section.
IMPORTANT!
If the data shown in digital numbers on
any screen on this unit is
flashing,
then it means that data is invalid. Do not rely
on that data if it is flashing.
For example, if the position display is
flashing,
then the unit has lost the
satellites and hasn't re-aquired them. The
position that is
flashing
is your
last known
position, notyour present position! Do not
navigate
with this unit
until you have found the reason the unit has lost the satellites!
Each of the
following
screens is available by
first pressing the MENU key,
then pressing the key next to the desired screen label. A detailed
description of each screen follows.
SATELLITE INFORMATION SCREEN
The satellite information screen shows technical data about each satellite
in view. The UltraNav II has a five channel GPS receiver. Data on each
channel is shown
atthetop
of the
display.
The channels are numbered one
through five on the left side of
the screen. Every satellite in
the
constellation has a number ______
assigned
to it, called the PRN. ____
The
PRN is the first number in
the channel's row. TIRK stands
for
"track.' If the UltraNav II is
tracking
the
satellite, then a 'T'
is placed in this column. If the
UltraNav II issearchingforthe
satellite, then a 'S' appears.
ELV is the elevation (height)

FASTRAK
This feature
converts all ech-
oes to short horizontal lines on
the display's
far
right side. The
graph continues to operate
• normally. FASTRAK
gives you
a rapid update of conditions
directly
under the boat. This
• makes it useful for ice fishing,
or when you're fishing at an-
chor. Since the boat isn't mov-
ing,
fish
signals
are
long, drawn
out lines on a normal chart dis-
play. FASTRAK converts the
graph to a vertical bar graph
that, with practice, makes a
useful addition to fishing at a
stationary location.
To turn FASTRAK on, press
the menu key four
times, then
press the key adjacent to the
"TURN FASTRAK ON" label.
To turn it
off, repeat the same steps.
The 'TURN FASTRAK OFF" label
appears instead of the "TURN FASTRAK ON" label.
