is strictly meant for recreational diving use; do not use it for any
other underwater activities
However, individuals who do not understand or have not taken proper
training in NITORX diving should not use the dive computer for NITROX
diving. Also, it is extremely dangerous to enter incorrect NITROX information
into the dive computer to the actual gas being used. Always reset each time
you dive and have your dive buddy to double-check the setting, never dive
with incorrect settings.
This dive computer is designed with the assumption that only one individual
alone will use it. If the unit is lent to another person, be sure to clear all
records so only new data can be collected for calculation (i.e. Desaturation
time, PGT indicator and OLI indicator should be 0).
The unit should never be
lent to someone else when repeated dives are planned.
