UPWARD POINTING ARROW, BLINKING ASC

TIME AND AN ALARM TELL YOU TO ASCEND. MINIMUM

TOTAL ASCENT TIME INCLUDING MANDATORY SAFETY

STOP IS 15 MINUTES. CEILING IS AT 3 M.

Display above the floor

When you ascend above the floor, the ASC TIME display stops blinking and the upward pointing arrow disappears. Below is an example of a decompression dive above the floor.

UPWARD POINTING ARROW HAS

DISAPPEARED AND ASC TIME LABEL HAS

STOPPED BLINKING, MEANING YOU ARE IN

THE DECOMPRESSION RANGE.

Decompression will now begin, but is very slow. You should therefore continue your ascent.

Display at the ceiling zone

When you reach the ceiling zone, the display will show you two arrows pointing at each other (the “hour glass” icon). Below is an example of a decompression dive at the ceiling zone.

TWO ARROWS POINT AT EACH OTHER “HOUR GLASS”. YOU ARE IN THE OPTIMUM CEILING ZONE AT 3 M. AND YOUR MINIMUM ASCENT TIME IS 15 MINUTES.

During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling. You may surface only after the ASC TIME and CEILING labels have disappeared, which means that the decompression stop and any Mandatory Safety Stop have been completed. You are advised, however, to stay until the STOP sign has also disappeared. This indicates that the three minute Recommended Safety Stop has also been completed.

Display above the ceiling

If you ascend above the ceiling during a decompression stop, a downward pointing arrow will appear and a continuous beeping starts.

DECOMPRESSION DIVE, ABOVE CEILING. NOTE DOWNWARD POINTING ARROW, ER WARNING AND ALARM. YOU SHOULD IMMEDIATLY (WITHIN

3 MINUTES) DES CEND TO OR BELOW CEILING.

In addition, an Error warning (Er) reminds you that you have only three 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. (See Section 5.6. Error conditions).
