1.4.1 DIGITAL WATCH DISPLAY
The digital watch display is the “home” display
of Matrix. In this mode, you have a central
ribbon with the current time in hours and
minutes, while the top and bottom portions of
the display can be customized.
To change what is displayed on the top portion,
press the top right button. The choice is
between a blank field, the current date, the set
alarm time and the second time (useful when
travelling to a different time zone).
To change what is displayed on the bottom
portion, press the bottom right button. The
choice is between a blank field, the temperature
and the battery level. Note that the temperature
reading will be affected by your body heat while
you are wearing the watch.
1.4.2 ANALOG WATCH DISPLAY
From the digital watch display, press the top
left button to switch to a simulated analog
watch display.
1.4.3 DIGITAL COMPASS
From either watch display, press and hold the
top left button to reach the digital compass
display. Matrix has a tilt-compensated digital
compass which can be used at almost any
inclination. The compass can be called up at
any moment during the dive and it can also be
used on the surface. This menu allows you to
use the compass on the surface and also to set
a bearing for reference during your next dive.
Note that for optimum energy management
the compass times out after 8 seconds when
on the surface.
The number shown in the middle of the
compass rose represents the bearing, between
0 (North) and 359.
1.4.3.1 SETTING A BEARING
Setting a bearing is useful for instance if you
are on a boat and there is a landmark on the
shore that you can use for alignment to reach
a specific spot on that dive site. Press the top
right button and a dot will appear to indicate
the set bearing. Additional symbols will appear
as well: squares at 90 degrees, triangles at
120 degrees and two parallel lines at 180
degrees, as an aid in navigation for square,
triangular and reciprocal courses. The number
at the bottom represents the deviation of the
direction you are pointing at with reference to
the set bearing.
Once underwater, align the dot with the arrow
and start swimming in that direction. If you
press the top right button again, the new
bearing will override the one in memory. If you
press and hold the top right button you erase
the bearing.
1.5 IN CASE OF EMERGENCY ICE
Matrix allows you to enter information about
yourself, such as name, contact information,
emergency number, insurance policies and
allergies. This information is entered via the
PC software Dive Organizer. Alternatively, it
can also be entered via Diver’s Diary (Mac
software). To view the information on Matrix
press the bottom left button from either watch
or from the post-dive display.
