SPEAKER VOLUME ______________
The speaker
volume has two steps -
low and high. The speaker
volume is
high
when
the unit is first turned on. To
change it,
first press
the menu key
five
times. Now press the
key adjacent to
the 'SET SPEAKER VOLUME LOW"
label. To switch back to the high vol ___________

CONTRAST
The unit's display
contrast is ad _________
justable to suit different lighting
conditions. To
adjust
it, first
press
the menu key five times. The
menu
shown above
appears. Now
press
the
key
next to the "ADJUST
DISPLAY CONTRAST' label. The
display
contrast arrows appear
on

increase the contrast, press the
key adjacent
to the
up arrow. To
decrease
it, press
the
key next to

MEMORY
The UltraNavGPS saves all settings such as sensitivity, chart speed,
display contrast,
and more in battery backed-up memory. This
memory
is retained
even
if
power
is disconnected from the
unit. If
you
wish to turn
the memory save feature off, press the key adjacent to the "TURN
M EMORYSAVE
OFF" label on the fifth sonar menu page. This does NOT
affect GPS initial
settings, waypoints,
or routes. Toturn

feature on again, press
the MENU key
until the fifth page
appears, then
press the
key next to the "TURN MEMORY SAVE ON" label.
degrees, 50.853 minutes. Below
the
present position
is course over
ground
(COG). This is expressed in degrees true or magnetic, depending on the
mode the UltraNavGPS is in. Course over
ground
is the direction the boat
is travelling. In other
words, if the COG is 180 degrees,
then the boat is
heading due south.
Fix displays
beneath the SaG. Fix shows how well the
latitude/longitude
filter in
the receiver is
working. The best
fix
number is nine
(9),
the worst is
one (1). As the fix number
decreases,
the
position's "jitter"
increases. Jitter
is the small position changes around a
location. In other
words, if
you hold
the
boat perfectly still,
you'll see the position displayed
on the unit "jump
around."
Very small position changes will
constantly
occur, This is called
jitter;
it's normal and
happens in all electronic navigation devices. If
the fix
number and HDOP numbers are
good, then the
latitude/longitude position
shown on the display
should also be good, excluding
the effect of S/A
(selective availability). Also see the Engineering Screen section.
Water
depth shows at the bottom of the screen. This is the
depth of
water from the face of the
transducer to the bottom.
STEERING SCREEN
The
steering screen shows a
pictorial viewof
your
boat and coursetravelled.
This is called a
Course Deviation Indicator or CDI. It also
shows Distance
To Go (DTG), Bearing to Waypoint (BRG), Course Over Ground (COG),
and water
depth (DEPTH).
Your
present position
is shown
by
the circle
with an arrow inside. The arrow
shows the direction the boat is
heading relative to the
waypoint. In
theory,
if
you steer the boat with the arrow always pointing towards the
waypoint,
then
you will arrive at the
waypoint. The solid
line extending from the circle is
yourtrack.
To
travel
directly
to a
waypoint, try to keep
the
circle on the center line. The waypoint is
depicted by
anothercircle at
thetopofthe
CDI
display. As you approach the
waypoint, the
two circles will move closer
together. If
you
travel
past
the
waypoint, the
waypoint's circle
will move to the bottom of the
display.
The numbers
immediately below the CDI are
the CDI
range
in miles. This
gives you
an idea
of how faroff course you
are. For
example, if
the circle is halfway between the course line
