POWER SUPPLY
The ATMOS ai utilizes one (1) 3 volt, CR2450 Lithium Battery that should provide from 300
dive hours of operation if you conduct one 1 - hour dive each time the unit is activated, to over 600
dive hours of operation if you conduct two or more dives each time the unit is activated.
Battery Indicator
A Battery Indicator (icon) provides an indication of Battery condition. The Battery Indicator
will be displayed during Surface Mode (Fig. 5a). It will not be displayed during Dive Modes.
Low Battery Condition
Voltage level is checked upon activation and every 10 minutes during operation.
Once 75% of full power is consumed, the Indicator will display only one bar and the icon will
flash once per second as a warning that the Battery is to be changed prior to conducting any fur-
ther dives with the unit.
If a Low Battery Condition exists when the unit is activated (by pressing the button), the Bat-
tery icon will appear flashing once per second for 5 seconds followed by shutdown of the unit.
If the button is not pressed to activate the unit prior to a dive, and
a Low Battery Condition exists, the Low Battery icon will appear
flashing as a warning upon descent past 4 feet (1.2 meters). No
other information will be displayed and the unit will not enter
Dive Mode.
If the unit did not display the Low Battery icon 'prior to' entering
the Dive Mode, and a Low Battery Condition occurs during the
dive, there will be sufficient Battery power to maintain unit op-
eration for the 'remainder of that dive'. The Low Battery icon will
appear flashing upon surfacing when Surface Mode is displayed.
