5.2.2. DIVE TIME ALARM

The instrument has one Dive Time Alarm Setting, which can

be used for several purposes to add to your diving safety (Fig

5.10). The alarm can be set, for example, to your planned bot-

tom time. The Dive Time alarm can be set on or off and the ti-

me from 1 to 999 minutes (Fig.5.11).

5.2.3. NITROX SETTINGS

If set to the Nitrox mode, the correct oxygen percentage of

the gas in your cylinder (and additional gases) must always

be entered into the computer to ensure correct nitrogen and

oxygen calculations. Also, in Nitrox mode, the oxygen partial

pressure limit must be set. When in the Nitrox Setting mode

the equivalent allowed maximum depth based on the chosen

setting will also be displayed. Settings for additional mixes

(MIX2, MIX3) are made similarly but with the selection of “ON”

or “OFF” for these.

In order to minimize the risk of error during the dive it is highly

recommended that the mixes are set with proper order. This

means that as the mix number rises so does oxygen content

and this is the order they are usually used during the dive. Be-

fore a dive set “on” only the mixes you actually have available

and remember to check the set values so they are correct.
