Chapter 1: Operation
If for any reason depth information is lost, the DEPTH title will flash
once per second and the displayed depth value will be the last good
reading.

Depth alarm threshold displays

The alarm threshold 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 arrow for a shallow alarm or a down
arrow for a deep alarm. The shallow and deep anchor alarms are
identified by means of an additional anchor icon.
You can enable and disable individual alarm thresholds by pressing the
reset key for 2 seconds, while the relevant alarm threshold is
displayed.
Each alarm threshold 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.

Adjusting alarm thresholds

To adjust the alarm threshold levels, press the trip and reset keys
simultaneously to enter adjust mode, then use either the trip key (to
decrease) or the reset key (to increase) the threshold value. When you
have set the required value, momentarily press the trip and reset keys
again, to save the alarm setting and exit the adjust mode.
Note: Adjustment of the shallow alarm threshold can be disabled
during calibration. When adjustment is disabled, you cannot enter
adjust mode.

Speed

Use the speed key to select the required information, as shown in the
Using the speed key illustration. The speed measurement units are
either knots (KTS), miles per hour (MPH) or kilometres per hour (KMH),
as selected during user calibration (see Chapter 4, Calibration).
The maximum speed, average speed and VMG to windward are each
displayed for a nominal 7 seconds, and if no action is taken during that
time, the display will timeout to the Boat speed display.
