with a graphic representation of the tank
pressure (
CLASSIC and FULL only). From
this menu you can also call up the gas
summary table described in section 1.12.
The RBT (remaining bottom time) is the
time you can spend at the current depth
and still have enough gas supply to make a
safe ascent and reach the surface with the
tank reserve. The RBT calculation is based
on your current breathing rate, accounts for
any existing and upcoming decompression
obligation and for any temperature gradient
in the water. It assumes an ascent at the
ideal ascent rate (defined in section 3.2.1).
A higher value of the tank reserve is more
conservative, but limits your diving time. A
lower value gives you more diving time but
the risk of running out of gas supply before
reaching the surface increases.
The sensitivity of the workload calculation
to changes in breathing pattern can be
adjusted in 25 steps: this has an effect on
how the algorithm accounts for changes
in breathing pattern in the decompression
calculation.
The oxygen bar graph can be replaced
with a graphic representation of the tank
pressure (
CLASSIC and FULL only). If
you turn ON this feature, the label of the
bar graph changes from
O
2
to
TNK
. To
use this feature, you must define a value
of the pressure when the tank is full.
Each segment in the left bar graph then
represents one tenth of the full value.
For instance, if the pressure of the full
tank is 200bar/3,000psi, each segment
will correspond to 20bar/300psi. As you
consume the gas in the tank, the segments
will gradually turn off.
2.8.3 Backlight duration
(default: 6 seconds)
You can set the duration of the backlight in
dive mode between 2 and 12 seconds or
to
PUSH ON/PUSH OFF . The backlight is
activated by pressing the “ LIGHT ” button.
If you choose
PUSH ON/PUSH OFF
,
the light will stay on until you press the
“ LIGHT ” button again to turn it off.
F
NOTE:
- The backlight consumes battery
energy: the longer the backlight
stays on, the shorter the life of your
battery.
- If the
LOW BATTERY
warning is
activated, it is no longer possible to
activate the backlight.
