DECOMPRESSION DIVE, ABOVE CEILING.

NOTE DOWNWARD POINTING ARROW, ER WARNING

AND ALARM. YOU SHOULD IMMEDIATELY (WITHIN

3 MINUTES) DESCEND TO OR BELOW CEILING.

In addition, an Error warning (Er) reminds you that you have only three (3) minutes to

correct the situation. You must immediately descend to, or below, the ceiling.

If you continue to violate the decompression, the dive computer will go into a permanent

Error Mode. In this mode, the instrument can only be used as a depth gauge and timer.

You must not dive again for at least 48 hours (refer to Section 5.5. Error conditions).

6.2. Diving in MIXED or CCR mode

The MIXED mode is used when diving with open-circuit air or with oxygen- or helium-

enriched gas mixes and it allows setting up to eight different gas mixes. The CCR

mode is used when diving with a rebreather and it allows setting up to three diluent

gases and up to eight different gas mixes. Refer to Section 5.9. Before diving in the

MIXED or CCR mode

6.2.1. Oxygen and helium displays

When the DIVE MIXED or CCR mode is activated, the display will show the information

in the figure below. In the MIXED mode, the maximum operational depth is calculated

based on set O

%, He% and PO

values. In CCR mode, the PO

value denotes the

currently selected set point.
