how to access these
features
from the menus.
The
initialization
is
identical.)
Use this
function if
you
don't
know
your position.
The UltraNav
will
calculate
your present position
using
the
chain
you
select.
See the
charts
in the back of this
manual for the
proper
chain to use
in
your
area.
Once
you
know the
chain's
number, press
the menu
key
while
the loran
screen is
displayed.
Now
press
the
key adjacent
to
the
"CHANGE
SETUP" label.
Finally, press
the
key adjacent
to the
"SELECT
CR1" label. A screen
similar to the one
shown below
appears.
The GRI for the
chain is shown
at the
top
of the screen.
The chain's
name is
right

To
change
the CR1,
press
the

This scrolls the

window.
When the desired

displayed
in the

The UltraNav
will
-___________
______
revert to the
last used loran screen
and
place
the
following
message
in a
_____________
______
window
on the
screen;
"Searching
for
CR1". The
UltraNav then looks
for
___________
the stations within
the selected chain.
Once it finds the
stations,
it
processes
the
signals
until it "locks on"
to each station in the
chain.
It
doesn't need to find and
lock onto
all the stations in a chain
to deter-
mine the
latitude/longitude.
However,
it does need to lock onto
three
stations with
good
signals
to calculate a
latitude/longitude.
To view
the UltraNav's loran station
acquisition
and
signal strengths,
see the
"STATION DATA" section
in this manual. Until
the loran finds all
of
the
necessary
stations in the
chain and locks onto them,
it flashes
the
latitude/longitude.
This
means the
latitude/longitude
display
is not
usable. When the
position
numbers
stop
flashing,
the loran is
ready
for use.
WARNING:
DO NOT NAVIGATE
WHEN THE POSITION
DISPLAY
(EITHER
LAT/LONG
OR
TD'S)
IS
FLASHING!
To save
a
waypoint
other than
your present
position,
first
press
the
Waypoint
Save
key.
The
waypoint
save menu
appears.
If
you
wish
to save the
waypoint using
latitude/longitude, press
the
key
adjacent
to the "INPUT
LL WPT" label. To save
a
waypoint
using
TD's,
press
the
key adjacent
to the "INPUT TD WPT"
label. The
steps
to save
a
waypoint
are identical.
For this
example,
we'll use the Iatitudef
longitude
method.
