classed as dangerous (see page 34): when your vessel reaches this

Timers

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

window that is displayed when you turn on the RayChart.
