set maximum oxygen partial pressure. Tissue calculation during dive is based on the mix you have selected.

The Vytec allows gas change to enabled gas mixes during the dive. Gas change is made by the following procedure:

•Press the MODE button until the Vytec starts to show blinking “MIX” instead of temperature/cylinder pressure in the lower left display (Fig. 3.27).

•Scroll between enabled mixes with PLAN and TIME buttons

•Mix number, O2% and PO2 for the mixes are shown when scrolling. If set PO2 is exceeded it will be shown with the value blinking and upward pointing arrow

•Select mix by pressing MODE.

•If no button is pressed in 15 seconds the Vytec will go back to dive display without changing gas mix. The Vytec does not allow change to a gas when set PO2 is exceeded. In such a case the mix is shown but cannot be selected (“select” text is not shown).

Upon ascent the Vytec prompts you to change gas when the PO2 level you have set for next mix is allowing a gas change. The prompt is an audible three beeps and the current mix O% starts to blink.

NOTE: The Vytec will not let you switch to gases which maximum PO2 levels are exceeded.

3.5. DIVING IN GAUGE MODE

If set to Gauge mode, the dive computer can be used as a bottom timer for diving with technical diving mixed gases. If you are trained for techni- cal diving and you plan to use Gauge mode on a regular basis, it may be preferable to set the instrument permanently to its Gauge mode. The Gauge mode is enabled in the MODE-SET-SET PREF-MODEL submode (see section 4.3. “Set Modes”).

If set to Gauge mode the text GAUGE is shown after activation (Fig. 3.4.).

In the Gauge mode the total Dive Time is always displayed in minutes in the lower right corner. In addition a Dive Timer in the center window displays time in minutes and seconds. The center window Dive Timer is activated at the start of the dive and it can be reset during the dive and used as a stopwatch by pressing the PLAN button.

When the PLAN button is pressed during the dive:

•A special mark, bookmark is written in the proﬁle memory.

•The Dive Timer shown in the center window is stopped, reset and started again.
