SUUNTO EON STEEL - Manual (Page 9)

WARNING: DO NOT EXPOSE ANY PART OF YOUR DIVE
COMPUTER TO ANY GAS MIX CONTAINING MORE THAN 40%
OXYGEN! Enriched air with greater oxygen content presents a risk
of fire or explosion and serious injury or death.
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 there is a desire to adjust the
computer to provide more conservative calculations, use the
personal adjustment feature to affect decompression calculations or
reduce the PO2 setting to affect oxygen exposure according to the
entered O2% and PO2 values. As a safety precaution, the oxygen
calculations in the dive computer are made with an oxygen
percentage of 1% + set O2%.
WARNING: SET THE CORRECT ALTITUDE SETTING! When diving
at altitudes greater than 300 m/1000 ft, the altitude setting 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 setting or diving above the maximum altitude limit will
result in erroneous dive and planning data.
