Low Air Pressure Warnings

The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/725 psi.

Three double beeps are also heard when the cylinder pressure goes down to the user-selected alarm pressure and when the remaining air time reaches zero.

6.1.4. Ascent rate indicator

The ascent rate is shown graphically along the right hand side. When the maximum allowed ascent rate is exceeded, the lower segments start to blink with the top segment staying solid, indicating that the maximum ascent rate has been exceeded continuously or that the current ascent rate is significantly above the allowed rate.

WARNING DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompression model will penalize your next dive(s). Continuous ascent rate violations will result in Mandatory Safety Stops. When Recommended Deep Stop is enabled, the length is indicated in seconds.

6.1.5. Safety Stops

A 3 minute Recommended Safety Stop is prompted after every dive to over 10m.

6.1.6. Decompression dives

When your NO DEC TIME becomes zero, your dive becomes a decompression dive so you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear. An upward pointing arrow will also prompt you to start your ascent.

If you exceed the no-decompression limits on a dive, the dive computer will provide the decompression information required for ascent. After this, the instrument will continue to provide subsequent interval and repetitive dive information.

Rather than requiring you to make stops at fixed depths, the dive computer lets you decompress within a range of depths (continuous decompression).

The ascent time (ASC TIME) is the minimum amount of time needed to reach the surface in a decompression dive. It includes:

the time needed to ascend to the ceiling at an ascent rate of 10 m/33 ft per minute. The ceiling is the shallowest depth to which you should ascend

the time needed at the ceiling

the time needed at the Mandatory Safety Stop (if any)

the time needed to reach the surface after the mandatory decompression dives have been completed
