4.3. AIR AND ENRICHED AIR

NITROX SETTINGS [EAN]

In this setting mode you can either select one scuba dive

mode (standard air and enriched air nitrox) or disable

both. If you select ON then you have a choice of whether

to have either Standard Air or Enriched Air Nitrox as

the operating option.

If set to the EAN (Nitrox) mode, the correct oxygen

percentage of the gas in your cylinder must always be

entered into the computer to ensure correct nitrogen and

oxygen calculations. Also in EAN mode, the oxygen

partial pressure limit must be set. When in the EAN

Setting mode the equivalent allowed maximum depth

based on the chosen setting will also be displayed.

To set the Air/EAN:

1. In the Setting Mode, press

S three (3) times to select

the EAN Setting Mode (Fig. 4.7.).

2. Wait two seconds until the EAN Setting Mode

activates automatically. The enable/disable status [On/

OFF] starts to blink on the display (Fig. 4.8.).
