A1 USER MANUAL
The alternative displays in APNEA mode
can be scrolled by pressing the +/UP or -/
DOWN buttons and this changes the dive
time to the middle of the display as shown
below.
As with Gauge mode, the A1 in Apnea
mode doesn’t carry out any decompression
calculations. You can only switch to
APNEA mode if the computer is completely
desaturated. Also the A1 is locked in the
APNEA mode for 12 hours after shallower
than 5m dives and after deeper dives the
lock period is 24 hours.

5.1 Establishing Bluetooth
communication
The A1 can be connected via Bluetooth to
a desktop, laptop or handheld device for
downloading dive data, conguring dive
computer settings or uploading rmware
updates.
From the main menu, toggle down to
Bluetooth using the +/UP or -/DOWN
buttons. Press the SEL/ESC button.
At this point the A1 is ready for Bluetooth
communication. Bluetooth is active only
when this screen is displayed.
To achieve Bluetooth communication with
another device, set the device you want
your A1 to communicate with (e.g. an iOS
or Android handheld device) to “scanning”
mode.
The rst time you do this will require
entering a pin code to ensure secure
communication. This pin code is shown on
the A1’s screen.
