Timers; Fix Status - Raytheon RayChart 620 Operation Manual

68
• Danger zone alarm specifies the radius of a circle around marks
classed as dangerous (see page 34): when your vessel reaches 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

Fix Status

The FIX STATUS option allows you to access the position fixer status
window that is displayed when you turn on the RayChart.
When a fix has been acquired, the text "Fix Good" is displayed at the
top of the screen, and the vessel's position at the bottom, together with
the HDOP (precision) factor and the Speed Over Ground (SOG).
