Suunto D9 [77/122] Audible and visual alarms

- Following any dive that required a decompression stop, ﬂ ying should be de-

layed for at least 24 hours, and if possible, for 48 hours.

- Suunto recommends that ﬂ ying is avoided until all the DAN and UHMS guide-

lines and the dive computer wait to ﬂ y conditions are satisﬁ ed.

6.6. AUDIBLE AND VISUAL ALARMS

The dive computer features audible and visual alarms to advise when important limits

are approached or to acknowledge preset alarms.

A short single beep occurs, when:

- the dive computer is activated.

- when the dive computer automatically returns to the TIME mode.

Three beeps with a three second interval occur, when:

- the cylinder pressure reaches 50 bar [725 psi]. The cylinder pressure display

will start to blink (Fig. 6.5).

- the cylinder pressure reaches the selected alarm pressure.

- the calculated remaining air time reaches zero.

Three beeps with a three second interval and activated backlight, when:

- the no-decompression dive turns into a decompression stop dive. An arrow

pointing upwards and the blinking ascent warning ASC TIME will appear (Fig.

6.10.).
