A1 USER MANUAL
4. DIVING WITH THE A1
The A1 is a full-featured diving computer
capable of Nitrox decompression
calculations, ascent rate calculations and
warnings. During a dive the A1 displays
information such as depth, dive time,
decompression status, water temperature
and much more. On the surface after a
dive, remaining desaturation time, no-fly
time, surface interval and prohibited altitude
classes are shown in addition to the watch
functions.
Note that the A1 can be set to three dive
modes: SCUBA, APNEA and GAUGE.
Due to the operational differences between
modes, the buttons will have different
functions depending on which mode you
are using.
The functions of the buttons
during diving
are summarized in the table below:
“LIGHT” Press = backlight
“SEL/ESC”
Press-and-hold in Apnea
mode when in “surface
interval” display = end Apnea
exercise
“+/UP”
Press = scroll through
alternative dive displays
Press-and-hold in GAUGE
mode when average depth
on display = reset average
depth counter
Press-and-hold in GAUGE
and SCUBA mode when
timer on display = stop/
restart the timer
“-/DOWN”
Press = scroll through
alternative dive displays
Press-and-hold in Apnea
mode when in “surface
interval” display = end Apnea
exercise
Press-and-hold in GAUGE
and SCUBA mode when
timer on display and stopped
= reset timer to zero
4.1 Display information
Upon immersion, the A1 will automatically
start to monitor the dive regardless of
what state it was in prior to the immersion.
Details on the information displayed can be
found in the next sections.
Dive time:
the dive time is displayed in
seconds in APNEA mode and in minutes
in SCUBA and GAUGE modes. If during
the dive you ascend to the surface, the
time spent on the surface will only be
counted to the dive time if you descend
again below 0.8m/3ft within 5 minutes.
This allows for brief periods of orientation.
While on the surface, the time will not
show as progressing but it is running in the
background. As soon as you submerge,
the time will resume, including the time
spent on the surface. If you spend more
than 5 minutes at a depth shallower than
0.8m/3ft, the dive will be considered
ended, it is stored in the logbook and a
subsequent immersion would cause the
dive time to start again from zero.
Maximum displayed time is 999 minutes.
For dives longer than that, the dive time
starts again from 0 minutes.
Depth: the depth is displayed in 0.1m
resolution when the metric system is
set. When depth is displayed in feet, the
resolution is always 1 foot. Maximum
operating depth is 120m/394ft.
No-stop time: calculated in real time and
updated every 4 seconds. The maximum
displayed no-stop time is 199 minutes.
WARNING
During all dives, perform a safety stop
between 3 and 5 meters/10 and 15 feet for 3
to 5 minutes, even if no decompression stops
are required.
The following chapter describes the
SCUBA mode diving functions, if you are
using GAUGE or APNEA dive modes, these
are further described in chapters
4.11
Diving in GAUGE mode and 4.12 Diving
in APNEA mode.
