POWER SUPPLY

The ATOM (Watch) utilizes 1 - 3 volt CR2430 Lithium Battery.

Transmitters use 1 - 3 volt, CR2 Lithium Battery.  When used as a

Dive Computer, the ATOM's battery should provide over 100

dive hours of operation if 2 dives are conducted during each

dive period.  The Transmitter's battery should provide over 1000

dive hours of operation.

Transmitters check battery voltage when they are pressurized and

will send a Low Battery signal to the Receiver in the ATOM when

the voltage drops below the Warning level.  The ATOM checks

its battery voltage every 2 minutes during surface operation.

•  If voltage of the ATOM decreases to the Warning level (2.75

volts), the Battery icon will appear (Fig. 4a) as an indication

that the Battery should be changed prior to commencing a

series of dives.

•  If voltage decreases to the Alarm level (2.50 volts), the Battery

icon will flash and operation will revert to Main Time.  The

ATOM would then operate in Watch modes until the Battery

becomes completely depleted.

•  Battery Status cannot be checked during Dive Modes.

•  If a Low Battery Condition was not displayed prior to starting

a Dive, and a Low Battery Condition occurs during the dive,

there will be sufficient Battery power remaining in the ATOM

to maintain it's operation for the remainder of that dive.
