POWER CONNECTIONS
The UltraNav I! works from a twelve-volt battery system. For the best
results, attach the power cable
directly to the battery. You can
attach the
power cable to an accessory or power buss, however you may have
problems
with electrical interference. Therefore, ifs saferto
go
ahead and
attach the
powercable
direotlytothe battery. If
the cable
istoo
short,
splice
#18 gauge
wire
onto it. The
power
cable has
four
wires; red, black, green,
and white. Red is the positive
lead, black is negative or ground. Make
certain to
attach the in-line
fuse holder to the
red lead as
close to the
power
source as possible. For
example, if
you have to extend the
power
cable to
the
battery
or
power buss, attach one end of the fuse
holder directly
to the
battery
or power buss.
This will protect both the unit and
the
power
cable
in the event of
a short.
The UltraNav II uses a
3-amp
fuse. There is
reverse
polarity protection built into the UltraNav II. If the power wires are
connected
backwards, no damage will occur to
the unit.
IMPORTANT!
Do not use this
product
without a
3-amp fuse wired into the
power
cable!
Failure to use a
3-amp
fuse will void
your warranty.
If you're
installing an
optional speed/temperature sensor, read the
speed/
temperature
sensor's installation manual for
mounting
instructions. Route
the
sensor's cable to the UltraNav Il's power
cable and plug it into the
connector marked "SPEED/TEMP CABLE'
The plotter display automatically shows a .1 mile display in the Man
Overboard mode. Your position when the Marl Overboard key was
pressed is
shown by
the "S' with a circle and by the
waypoint icon with a
"0" Steer
to the waypoint flag
to get back to the position saved when the
Man Overboard key was pressed.
IMPORTANT!
The UltraNav II doesn't save the Man Overboard position in the
waypoint
table.
However, it does save the
position on the Man Overboard screen.
The UltraNav II
always shows
navigation datato
the
position shown
on the
Man Overboard screen
whenever the Man
Overboard key is
pressed. To
stop
the
unitfrom
navigating
to the Man
Overboard position, press the
key
next to the "DISABLE MOB" label. This resets the Man Overboard
navigtion.
For
example, suppose you
are viewing the Position screen, and you press
the Man Overboard key, then press
the OPS key. The UltraNav II first
displays
then
stores your
present position on the Man Overboard screen,
then switches
backtothe Position screen. If
you press
the Man
Overboard
key again, it will still show navigation data to the
position you
were in when
you first pressed the Man Overboard key - not
your present position.
Repeated pressing of the Man Overboard key does not repeatedly save
your present
position!
The unit
onlysaves
the
position
thefirsttime the
Man
Overboard key is pressed. To save a new Man Overboard Dostion.
you
must first clear the old Dosition by pressing the key adiacent to the
"DISABL MOB" label.
You can navigate to a waypoint using the Waypoint Recall feature,
however
when
you go
back to the Man Overboard screen, the UltraNavIl
stops
navigating to the recalled
waypomnt.
Remember, saving
the victim is the
primary goal.
Try
all options
to rescue
the person immediately after the accident
happens. Training and educa-
tion are also good accident preventatives.
The
Coast Guard has
excellent
safety courses. Instruct all members on board your boat on safety
procedures before leaving
the dock. Make certain all on board know what
to do before
any emergency occurs.

saving
and
recalling waypoints, see "How to Save
a Waypoint" section in this manual.
