MAN OVERBOARD
One of
boating's mostterrifying events is
having afriend
orfamily
member
fall overboard. This situation can be deadly on
any body of
water,
fresh or
salt. It's particularly dangerous at night or if you're
out of
sight
of land. Of
course, the first thing
to do is remain calm and try all standard safety
measures
to
try and rescuethe
person. If
you lose sight
of the
person, you
can use the UltraNav II to help start a search pattern.
Once
you're back at the helm
after initial rescue efforts have
failed, press the UltraNav Vs
MAN OVERBOARD key. The
screen shown at
right appears.

another electronic navigation devices through
the white wire. The green
wire is for a differential GPS (DGPS) receiver input. If the white and
green wires are not used, tape their ends so that they
cannot short.
To connect a device to the UltraNav's NMEA output (white wire); attach
a two-wire shielded cable from the other device's NMEA intput
to the
white and black wires on the UltraNav il's power
cable. Solderthe shield
to the black wire on the power cable. Do not connect the shield to the
other device. See the other instrument's manual for more
wiring instruc-
tions. Use the same procedure to connect the DGPS receivers
output
to
the green and black wires on the UltraNav II.
Note: The
shielded wire is not absolutely necessary, however it is best
to use it due to the high electrical noise levels found in today's marine
environments. To avoid
problems later, we highly suggest
that
you use
shielded wires whenever making a communications connection between
two instruments. See the NMEA section in the GPS section in this
manual for more information.
GPS MODULE INSTALLATION
The GPS thodule can be installed on a flat surface or (with
the supplied
adapter) on a pole. Mount the module in an area that guarantees a clear
view of the sky
at all times. In order for the module to receive the
signals
from the satellites, it must not be obstructed. An ideal location is on a
cabin
roof, or deck. The gunnels also make a good location. Attaching
the pole mounting adapter
lets you in-
stall the module on a one inch mast.
However, for lightning protection, the
antenna shouln't be the highest part of
the boat.
Surface Mounting - With Access
If you have access underneath the
mounting surface, use the gasket sup-
plied with the GPS module as a tem-
plate. Drill four 5.5 mm (7/32a) holes
and one 17 mm (11/16") hole for the
module's cable. Attach the cable to the
module and pass it down through the
hole in
