8-7. Enriched Air Nitrox (EANx) Diving
EANx (Enriched Air Nitrox) is a mixed gas in which the percentage of oxy-
gen exceeds that which is used in compressed air.
The Z1 can be used with compressed air (21% O
2
), or with EANx (22%-100%
O
2
). In diving with Nitrox (EANx), in addition to tracking dive data during
an air dive, the Z1 monitors the 0
2
infl uence on the body relative to diving
depth to avoid oxygen poisoning.
When Nitrox (EANx) percentages are set, the O
2
% icon blinks when in
Watch Mode, and O
2
% and surface time are displayed alternately when in
Surface Mode.
If the date changes while GAS1 through GAS4 oxygen percentages are set
in the range of 22% to 100%, the O
2
% automatically returns to the default
21% O
2
(compressed air).

between Water Temperature and O
2
%.
