Menu item Description
Arrival Alarm Radius When you arrive at a
waypoint, an alarm is
triggered. This setting
allows you to specify the
distance from the target
waypoint at which the
alarm is triggered. The
units used for this setting
are based on the units
you specify for distance
in the Units Setup Menu.
Offtrack Alarm
When set to ON, an
alarm is triggered when
your vessel steers
off-track a greater
distance than the value
you specify for the
Offtrack Alarm XTE
setting (see below).
Offtrack Alarm XTE Specifies the distance

equivalent units)
• OFF (default)
• ON
0.01 to 9.99 nm (or
equivalent units)
Description Options
When Collision Alarm is • OFF (default)
set to ON, an alarm is
• ON
triggered when charted
objects appear in the
alarm zone's vicinity.
The zone is set up using
the Setup Alarm Zone
setting (see below). You
must also set the Display
Alarm Zone setting (see
below) to ON in order
to view the zone in the
chart application.
Note: The accurate
operation of the
collision alarm is
dependent on you
supplying suitable
values for the Boat
Details setting
(MENU > System
Setup > Boat
Details), which must
be appropriate for
safe navigation. The
values you specify
must also take into
account the position
of the GPS antenna
on your vessel, as
the collision alarm
uses data from the
GPS antenna.
