NOTES:
•
After pressing the ADJUST button to set Gas 2, if at this point you
set OFF and then press the ADJUST button again, the O
2
% setting
advances to the Safety Factor setting screen.
• The O
2
% setting can only be made so that the O
2
% becomes Gas 1
<Gas 2 <Gas 3 <Gas 4.
5. After making your gas settings, press-and-hold the MODE button for
about 2 seconds to return to Watch Mode or Surface Mode.
In Dive Mode it is possible to check the O
2

gas switching, but you cannot set or change the gas concentration set-

CAUTION
How to Switch Gases
1. During a dive, press-and-hold the ADJUST button for about 2 seconds
to display the gas switching/confi rmation screen.
2. If multiple gases have been set, the gas number and O
2
% will blink. By
pressing the PLAN button, the gas number advances. If the next gas in
line has not been preset, or if it cannot be dived, the Z1 will return to
gas 1.
NOTE: A gas cannot be dived when the ppO
2
exceeds 1.6 bar. If a gas
selected has a ppO
2
higher than 1.6 bar, a buzzer will sound and the Z1
will shift to a gas with lower O
2
%.
3. After confi rming the gas mix, press the ADJUST button to return to the
main Dive Mode screen. If 2 or 3 minutes elapse without pressing the
ADJUST button, the Z1 will automatically confi rm the currently selected
gas and return to the Dive Mode screen.
