DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU
HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND
ENTERED THE ANALYZED VALUE INTO YOUR DIVE
COMPUTER! Failure to verify cylinder contents and enter the
appropriate O % into your dive computer will result in incorrect
2
dive planning information.
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
decompression calculations. If you want to adjust the computer
to provide more conservative calculations, use the personal
adjustment feature to affect decompression calculations, or reduce
the PO setting to affect oxygen exposure.

SELECT THE CORRECT ALTITUDE ADJUSTMENT SETTING!
When diving at altitudes greater than 300 m/1,000 ft the Altitude
Adjustment 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 3,000
m/10,000 ft. Failure to select the correct Altitude Adjustment
setting, or diving above the maximum altitude limit will result in
erroneous dive and planning data.
