Operation Manual

Atmos Pro/Aeris 300G

MAX

After Total Ascent Time reaches zero and the Nitrogen Bar Graph recedes into

the yellow Caution zone, you can surface. However, to add a greater mar-

gin of protection, Aeris strongly recommends that you wait until the

segments of the Nitrogen Bar Graph are well within the 'green' No

Decompression zone, unless a low tank pressure condition requires

you to surface.

3. You descend deeper than 330 feet (99.5 meters).

NOTE: Aeris reminds you that the Atmos Pro/Aeris 300G is in-

tended for no decompression diving at depths within 130 feet

(39 meters). Expanded capabilities of the unit are provided as

safety features to assist you with emergency situations.

Upon descending deeper than 330 feet (99.5 meters), the Nitrogen and O2 Bar

Graphs will flash and the Current Depth and Maximum Depth displays will

only indicate the letters 'oor' (Fig. 59) until ascent is made to a depth shallower

than 330 feet (99.5 meters), at which time the Current Depth display will be

restored. Max Depth will continue to display 'oor'. Exceeding the maximum

operating depth is described in more detail on page 60 of this section.

Five minutes after reaching the surface from a dive in which a De-

layed Violation occurred, the Atmos Pro/Aeris 300G will enter an Im-

mediate Violation Mode and revert to Gauge Mode for 24 hours.
