ALTITUDE DIVING

The mathematical model within the 500AI accounts for the reduced No De-

compression dive time available at higher elevations based on NOAA (National

Oceanic and Atmospheric Administration) guidelines. When diving in high al-

titude lakes or rivers from 2,000 to 14,000 feet (610 to 4,268 meters), the

500AI will adjust automatically, providing corrected depth and reduced No De-

compression and Oxygen Exposure times.

WARNING: If activated above 14,000 feet (4,268 meters), the

unit will perform a diagnostic check and immediately shut off.

When above 2,000 feet (610 meters), depth calibration is automatically

changed to read in 'feet of freshwater' rather than' feet of seawater'.

WARNING: Until it has shut itself off, you must not use the

500AI at a different altitude than the altitude where it was

originally activated. Doing so will result in an error equal to

the difference in barometric pressure, and possibly a false dive

mode with erroneous data.

More about Altitude Diving is presented on page 88.
