Alarms
All the alarms default to OFF, that is, disabled. You can switch an alarm on and
adjust its setting to any value, in steps of 0.01. When an alarm is set, it will be
triggered when the alarm condition is met (see Chapter 4). All the alarms relate
to a specified distance.
To switch an alarm ON and adjust its value, select the alarm then press the top
side of the trackpad.
Note: The alarm limits are not displayed on the chart.
The alarms settings have the following functions:
• Arrival alarm specifies the radius of a circle around the waypoint: when
your vessel enters this circle the alarm sounds
• Off course alarm specifies the distance from the route, at right angles to the
route, beyond which the alarm sounds
• Anchor alarm specifies the distance from the anchor position beyond which
the alarm sounds; you can only set this if a position fix is available
• Danger zone alarm specifies the radius of a circle around marks classed as
dangerous (see page 41): when your vessel enters this circle the alarm sounds
Timers
The timer controls have the following functions:
• Countdown timer counts down from selected time (in hours, minutes and
seconds); an alarm is triggered when the timer reaches zero
• Elapsed timer counts up from zero, and is displayed in the cursor data box
on the chart
• Clock alarm, if set, sounds when the time data received by the system
matches the time specified here (in hours, minutes and seconds); you can
only select this if time data is being received
