OPERATIONAL PERFORMANCE

Function: Accuracy:

  • Depth ±1% of full scale
  • Timers 1 second per day

Dive Mode Activation:

  • Must be in Dive Computer mode, if Wet Activation is set OFF.
  • Automatic by immersion in water, if Wet Activation is set ON.
  • Cannot be manually activated deeper than 4 FT (1.2 M), if Wet Activation is set OFF.
  • Cannot operate as a DC at elevations higher than 14,000 feet (4,270 meters).

 Dive Counter:

  • NORM/GAUG displays Dives #1 to 24, FREE displays #1 to 99 (0 if no dive made yet).
  • Resets to Dive #1, upon diving (after 24 hours with no dives).

 Dive Log Mode:

  • Stores 24 most recent NORM/GAUG dives in memory for viewing.
  • After 24 dives, adds 25th dive in memory and deletes the older dive.

 Altitude:

  • Operational from sea level to 14,000 feet (4,270 meters) elevation.
  • Measures ambient pressure every 30 minutes in Watch mode, when Dive Computer mode is accessed, and every 15 minutes while in DC Surface modes.
  • Does not measure ambient pressure when Wet.
  • Compensates for Altitudes above sea level beginning at 3,001 feet (916 meters) elevation and every 1,000 feet (305 meters) higher.

Power:

  • Watch Battery (1) 3 vdc, CR2430, Lithium battery (Panasonic or equivalent)
  • Transmitter Battery (1) 3 vdc, CR2, .75 Ahr, Lithium battery (Duracell model DL-CR2 or equivalent)
  • Shelf life Up to 7 years (when shipped from factory in Deep Sleep mode)
  • Replacement User replaceable (annual recommended)
  • Use Life (ATOM 3.0) 1 year or 300 dive hours if (2) 1 hour dives per dive day
  • Use Life (Transmitter) 300 dive hours if (2) 1 hour dives per dive day

Battery Indicator (ATOM 3.0 only):

  • Warning >> icon on solid when <= 2.75 volts, Battery change recommended.
  • Alarm >> icon on flashing when <= 2.50 volts, change the Battery, will not function as a DC.

Operating Temperature:

  • Out of the water >> between 20 °F and 140 °F (-6 and 60 °C).
  • In the water >> between 28 °F and 95 °F (-2 and 35 °C).
