WARNING
THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL
PERCENTAGE VALUES OF OXYGEN CONCENTRATION. DO
NOT ROUND UP FRACTIONAL PERCENTAGES! For example,
31.8% oxygen should be entered as 31%. Rounding up will cause
nitrogen percentages to be understated and will affect decompres-
sion calculations. If there is a desire to adjust the computer to
provide more conservative calculations, use the personal adjust-
ment feature to affect decompression calculations or reduce the
PO
2
setting to affect oxygen exposure according to the entered
O
2
% and PO
2
values. As a safety precaution, the oxygen calcu-
lations in the dive computer are made with an oxygen percentage
of 1% + set O
2
%.
WARNING
SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When
diving at altitudes greater than 300 m/1000 ft, the Altitude Adjust-
ment feature must be correctly selected in order for the computer
to calculate the decompression status. The dive computer is not
intended for use at altitudes greater than 3000 m/10000 ft. Failure
to select the correct Altitude Adjustment setting or diving above
the maximum altitude limit will result in erroneous dive and plan-
ning data.
