GALILEO 2 TEK (G2TEK) USER MANUAL
no-fly time is also the time during which you
cannot switch back to computer mode.
The Gauge mode surface display after a
dive shows the dive time in the top row. In
the middle row the stopwatch is running
from the dive start or last manual restart.
In the bottom row the maximum depth of
the dive is shown. After a 5-minute timeout
the display changes to Gauge menu mode.
During a dive in Gauge mode, the G2TEK
displays a stopwatch. This can be reset
and restarted by pressing the SW button
which also sets a bookmark.
With a press-and-hold of the SW button
the gas switch procedure can be started.
While in Gauge mode, the average depth
can be reset. To reset the average depth,
press the AVG button which also sets a
bookmark.
With a press-and-hold of the AVG button
the profile is displayed followed by the
pictures.
Dimming the display screen is accomplished
by pressing the DIM button. A press-and-
hold of the DIM button will activate the
compass display.
3 .10 Apnea mode
The G2TEK has an advanced Apnea
diving mode which can be enabled from
the feature upgrade (see menu
8. Other
settings
). The main features include
a faster sampling rate than in Scuba
mode along with alarm functions tailored
specifically to Apnea diving.
The G2TEK measures the depth in Apnea
mode every 0.25 seconds to ensure the
precise maximum depth. In the logbook
the data is saved in 1-second intervals.
In Apnea mode it is also possible to start
and stop the dive manually with a press-
and-hold of the MENU button. This way
you can use the G2TEK for static Apnea
dives, where a normal dive start depth of
0.8 meters will not start a new dive.
As with Gauge mode, the G2TEK in Apnea
mode doesn’t carry out any decompression
calculations. You can only switch to Apnea
mode if the computer is completely
desaturated.
Apnea mode at the surface after a dive
shows the maximum depth and the dive
duration. The surface interval counter starts
after surfacing and the heart rate shows the
current measured value.
Dive session values like water temperature,
total dive time, number of dives and
minimum heart rate are shown with white
color as shown on the screen below.
