After entering values for Diluent 1, you can set additional diluents, Diluent 2 and
Diluent 3, similarly. You can set these to “ON” or “OFF”. Diluent 1 is always set as an
“ON” gas whereas Diluent 2 and Diluent 3 are “OFF” by default.

Only enable the diluent(s) you actually have available and remem-
ber to check the set values before every dive to ensure they are
correct.

If set to the DIVE MIXED or DIVE CCR mode, the correct oxygen and helium percent-
ages of the open-circuit gas(es) in all your cylinders (and additional gases) must always
be entered into the dive computer to ensure correct tissue and oxygen calculation. In
addition, the oxygen partial pressure limit must be set.
