SUUNTO VYTEC - Manual (Page 40)

• If a diver had less than 2 hours total accumulated dive time in
the last 48 hours, then a 12 hour surface interval before flying
is recommended.
• Following any dive that required a decompression stop, flying
should be delayed for at least 24 hours, and if possible, for 48
hours.
• Suunto recommends that flying is avoided until all the DAN and
UHMS guidelines and the dive computer wait to fly conditions
are satisfied.
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 the selected alarm pressure.
• 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.).
• Gas change is prompted
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.).
