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 UltraMap are
covered 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) can
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 an-
chored and your boat moves more than .1 of a mile, the alarm will flash a
message 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-
ting still. This typically happens when using small (less than .05 mile)
anchor alarm ranges. If you have a DGPS beacon receiver connected to
this unit, smaller ranges may be usable.
Arrival Alarm - If you set the arrival alarm’s distance to a small number,
