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 5.6. Error conditions

).

6.2. Diving in the MIXED mode

The MIXED mode is the first dive mode available in Suunto D9tx. The mode is used
when diving with air or with oxygen- or helium-enriched gas mixes.

6.2.1. Before diving in the MIXED mode

If set to theMIXED 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. The dive computer adjusts its mathematical nitrogen and oxygen calcu-
lation models accordingly. The dive computer will not accept fractional percentage
values of oxygen concentration. Do not round up fractional percentages. For example,
31.8% oxygen should be entered as 31%. Rounding up will cause inert gas percentages
