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) DESCEND 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).
