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 message.
To use any of these alarms, first press the MENU key,
then select the “ALARMS/CDI” menu. A screen similar
to the one shown at right appears. Press the up or down
arrow key to move the black box to 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 “DIST” menu item, then press the right or
left arrow keys to increase or decrease the alarm’s dis-
tance.
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
the Expedition II, smaller ranges may be usable.
Arrival Alarm - If you set the arrival alarm’s distance to a small number,
and you run a route (see the routes section), the Expedition II may not
show navigation data to the next waypoint, once you arrive at the first
one, since you may not be able to come close enough to the first waypoint
to trip the arrival alarm.
MESSAGES
The position and DGPS message selections are found on the Alarms/
CDI menu. When turned on, the position message appears for a few sec-
onds whenever the unit locks onto the satellites and shows a position. It
also appears when the unit loses the lock onto the satellites and cannot
navigate. Pressing the EXIT key erases these messages.
The DGPS message appears whenever the unit begins or stops using
DGPS data to help determine your position.
The default setting for these messages is “on”. To turn either message off,
select the “Setup Alarms” menu from the main menu, then highlight the
desired message and press the left arrow key.
