ing" plot trail seen when you're stopped with position pinning turned off.
This also affects the navigational displays.
The easiest way to see the effects of S/A is to stand still with the GPS
receiver turned on and watch your plot trail with position pinning turned
off. You'll see the present position change, speed increase and decrease,
and a random plot trail on the plotter's screen.
If you wish to turn the position pinning feature off, press the MENU key,
then highlight the "GPS Setup" label and press the right arrow key. Now
highlight the "POSITION PINNING" label. Finally, press the left arrow key.
ALARMS
This unit has several GPS alarms. (Sonar alarms for the Status are cov-
ered in the sonar section of this manual.) You can set an arrival alarm to
flash a warning message and sound a tone when you cross a preset
distance from a waypoint. For example, if you have the arrival alarm set to
.1 mile, then the alarm will flash a message when you come within .1 mile
of the recalled waypoint. The course deviation indicator alarm (CDI) warns
when your track drifts too far to the right or left of the course line to the
waypoint. For example, if the alarm is set to .1 mile, then the alarm flashes
a message if you drift .1 of a mile or more to the right or left of the line to
the waypoint. The anchor alarm is triggered when you drift outside of a
preset radius. Again, using the .1 mile as an example, if you're anchored
and your boat moves more than .1 of a mile, the alarm will flash a mes-
sage and sound a tone.
To use any of these alarms, first press the MENU
key, then select the "ALARMS" menu. Next, se-
lect "GPS ALARMS". A screen similar to the one
shown at right appears. Press the up or down
arrow key to select the desired alarm, then press
the right arrow key to turn it on.
To adjust an alarm's distance, move the black
box to the alarm's "DIS" menu item, then press
the right or left arrow keys to increase or decrease
the alarm's distance.
When you're finished, press the EXIT key to erase this menu.
Important Alarm Notes:
Anchor Alarm - Since civilian users don't receive the accuracy given to
military users, the anchor alarm may be triggered even when you're sit-
