Depth alarm level displays
Alarm displays are available if the instrument is operating as a master. Each
display is identified by the presence of an alarm symbol ( )and either an up
depth trend arrow for a shallow alarm or a down depth trend arrow for a
deep alarm. The shallow and deep anchor alarms are identified by means of an
additional anchor symbol ( ).
You can enable and disable individual alarms by pressing the reset button for
2 seconds, while the relevant alarm screen is displayed.
Each alarm screen is displayed for a nominal 7 seconds, and if no action is taken
during that time, the display will timeout to the current depth display.
