A1 USER MANUAL
F
NOTE: Swim mode stays active in
shallow water down to 3 meters. This
allows flip turns in pool and horizontal
dives. An immersion deeper than 3
meters will start a dive in the mode
which is selected in the A1 (SCUBA,
APNEA or GAUGE).
2.2.3 Apnea mode
Apnea exercise mode can be activated
from this next menu. The session starts
with a surface interval.
Apnea mode settings are described in
chapter
3.2.3 Apnea mode settings .
Display information and diving with this
mode is described in chapter
4.1.2.3
APNEA mode.
2.3 Reading the altitude,
barometric and
temperature values
From the main menu toggle to the
Altimeter (Altimtr) menu, and press the
SEL/ESC button to enter. In the Altimtr
menu, on the first display the current
altitude (in meter or feet) is calculated from
the barometric pressure and shown in the
middle of the screen. The temperature (in
Celcius or Fahrenheit) and air pressure (in
mbar) at your current altitude are displayed
in the bottom left and bottom right of the
screen, respectively.
F
NOTE: barometric pressure is a
variable, changing with weather and
atmospheric pressure at a particular
elevation. The Dive algorithm uses
Altitude Classes which are directly
derived from the barometric pressure.
Altitude is counted from the current
barometric pressure and is therefore a
relative value.
By pressing the +/UP or -/DOWN buttons
you can switch to an additional display
where the atmospheric pressure at sea
level is shown.
The altitude can be adjusted when current
elevation is known by pressing the SEL/
ESC button. The new altitude value will
be highlighted in the center of the screen.
By pr/UP or -/DOWN buttons
the value can be adjusted in 10m/50ft
increments.
This Barometer feature allows you to
foresee approaching weather in the
upcoming hours if your altitude remains the
same.
