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
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.
SELECT THE CORRECT PERSONAL ADJUSTMENT SETTING!
Whenever it is believed that factors that tend to increase the
possibility of DCI exist, it is recommended that you use this option
to make the calculations more conservative. Failure to select the
correct Personal Adjustment setting will result in erroneous dive
and planning data.
