3. Use the up or down soft keys to change the alarm setting. For example, for
the arrival alarm you can adjust the radius from the waypoint at which the
arrival alarm will be triggered.
The arrival, off track and anchor alarm distances can be set in the range
0.01 to 9.99 nm, in steps of 0.01nm.
The grounding alarm depth can be set from 1 to 20m in 1m steps and can be
specified to cover a sector at a range from 0 to 1nm, in 0.1nm steps.
The timer is set in hours, minutes and seconds, and the alarm clock in hours
and minutes.
4. If desired, press the
ALARM OFF ON
soft key to toggle the alarm on or off. If
you turn an alarm off, its value is retained and will be used when you turn
the alarm on again.
Note: You can turn all the alarms and timers on and off, except for the Arrival
Alarm which is always on.
5. Press
ENTER
to save the changes and clear the list.
