3.7. 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 double beeps occur, when:
• the cylinder pressure reaches 50 bar [725 psi]. The cylinder pressure
display will start to blink (Fig. 3.12.).
• the cylinder pressure reaches 35 bar [500 psi].
• the calculated remaining air time reaches zero.
Three single beeps with a two second interval and the backlight activated for
5 seconds occur, 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. 3.16.).
Continuous beeps and the backlight activated for 5 seconds occur, when:
• the maximum allowed ascent rate, 10 m/min [33 ft/min], is exceeded.
SLOW and STOP warnings will appear (Fig. 3.13.).
• the Mandatory Safety Stop ceiling is exceeded. A downward pointing
arrow will appear (Fig. 3.15.).
• the decompression ceiling depth is exceeded. An error warning Er and a
downward pointing arrow appear. You should immediately descend to,
or below, the ceiling. The instrument will otherwise enter a permanent
Error Mode within three minutes, indicated by a permanent Er (Fig.
3.19.).
