MENU Description
SET COMPUTER
LANGUAGE
Allows you to set the language
for the user interface, all
menus and warning messages
during the dive.
UNITS
Allows you to choose between
metric (m,°C, bar) and
imperial (ft,°F, psi) units.
CLOCK
Allows you to set the date,
time, time zone shift when
travelling, and a wake-up
alarm.
BRIGHTNESS
Allows you to set the
maximum brightness of the
backlight.
COMPASS
DECLINATION
Allows you to compensate
between magnetic north
and geographic north in the
digital compass.
COMPASS
CALIBRATION
Allows you to recalibrate the
compass.
3.1. LANGUAGE
In this menu you can set the language for the
user interface and for alarm messages during
the dive.
3.2. UNITS
You can choose between metric (depth in
meters, temperature in°C, tank pressure in
bar) and imperial (depth in feet, temperature
in°F, tank pressure in psi).
3.3. CLOCK
This menu allows you to set the time format,
time, date, time zone shift and wake-up alarm.
3.4. BRIGHTNESS
This menu allows you to change the brightness
of the display to adapt to various levels of light
conditions. Upon entering this menu, a sliding
bar appears across the display. Use and
to set the brightness level.
3.5. COMPASS DECLINATION
Depending on the exact location on the planet,
there can be a deviation between true North
and magnetic North. Any compass will always
show magnetic North, so via this menu you can
set a value for the so-called declination that will
make the compass show true North instead.
3.6. COMPASS CALIBRATION
The digital compass in Genius is calibrated from
the factory and does not require, under normal
circumstances, any further maintenance.
In certain instances, however, such as after
exposure to extremely intense magnetic fields,
it may be necessary to recalibrate the compass
to ensure its accuracy. If you notice an obvious
deviation in the indication of the compass,
access this menu and perform the calibration
as described below.
First you must enter the security code, 1234.
Then the image shown in Figure 7 appears on
the display.
Now hold Genius horizontal to the surface
and perform one slow counter clockwise
circle. Once you have finished the circle, the
calibration is completed.
• 4. DIGITAL COMPASS
Genius 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.
The number shown in the middle of the
compass rose represents the bearing, between
0 (North) and 359.
4.1. SETTING A BEARING
With you can set a reference bearing. This
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 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
again, the new bearing will override
the one in memory. If you press and hold
you erase the bearing.
• 5. INFO
This submenu provides various information
about the hardware and software of your
Genius. It also lists information about the use
of the dive computer, such as longest dive,
deepest dive, total number of dives and total
dive time. These can be individually reset to
0 by pressing the right button (RESET). In
addition, you can revert to the original settings
configuration via the FACTORY RESET option
(this option is not available while there is
remaining desaturation in the computer). The
option FACTORY MAINTENANCE is for use by
authorized personnel only.
• 6. MAPS AND PHOTOS
These menus allow you to view all the maps
and pictures that have been uploaded via Dive
Organizer to your Genius. Any file in JPEG
format can be uploaded to Genius. Note that
only the files listed as maps can be selected
for the LINKED MAP function described in
section 2.12.
The memory of Genius can hold approximately
100 between maps and pictures.
• 7. BUTTON LOCK
This function allows you to lock the buttons
so that the computer is not turned on
inadvertently. This is very useful for instance
while travelling to a dive site, since otherwise
Genius might unintentionally drain the battery
before the dive.
To lock the buttons, press and hold SELECT
for one second from the main menu, or press
it normally when the BUTTON LOCK icon is
highlighted. This will blacken the display.
To unlock the buttons, press the left button
followed by pressing the right button. The
home display now reappears.
