Info

• No decompression dive modeThe following data applies to dives that do not exceed the no decompression limit.• Maximum depth:This shows the maximum depth measurement since the start of the dive.• No decompression limit:This shows the maximum amount of time allowable at the current depth withno decompression, calculated based on dive data so far.• Decompression dive modeThe following data applies to dives that exceed the no decompression limit.• Decompression stop depth:Decompression stop depths include 49 feet (15 meters), 39 feet (12 meters),30 feet (9 meters), 20 feet (6 meters), and 10 feet (3 meters).The stop depths are set according to the current dive data and are shown in asequence from deepest to shallowest.• Decompression stop time:This shows the amount of decompression time at each decompression stop depth,calculated based on the current dive data.The amount of decompression time is counted down at each decompression stop depth.• Total ascent time:This shows the total amount of time required for ascent to the surface, calculated basedon the decompression stops and an ascent rate of 24 feet per minute (8 meters perminute).**For further information on the different ascent rates see page 25The display alternates between decompression stop time and total ascent timewhen the total ascent time becomes a three-digit value while thedecompression stop depth remains unchanged.23
When switch A is pressed• Current time:The current time is displayed.• Current water temperature:The current water temperature is displayed.The temperature measurement is retaken at 1 minute intervals.• Partial pressure of oxygen (PO 2 ):The partial pressure is displayed at the current depth.This value is calculated based on the oxygen mix ratio setting and the current depth.Never allow this value to exceed 1.6 ATA during a dive.Note:1.6 ATA has been established as the maximum PO 2 value for safe diving.In this <strong>manual</strong>, the depth setting that causes this value to approach 1.6 ATA is definedas the maximum depth for a dive.The following warning functions are also provided for when hazards areencountered during a dive.• Default warningWhen the oxygen mix ratio is at the default setting, an alarm is sounded if the divecomputer is set to dive mode.When this alarm is sounded, do not start a dive until you have set an appropriateoxygen mix ratio via the oxygen mix ratio setting mode.The alarm sounds for three seconds.This warning is not recorded in the dive log.• Decompression warningThis display appears and an alarm is sounded for three seconds if the no decompressionlimit is exceeded and the dive mode changes to decompression dive mode.(The dive computer's display changes to decompression dive mode.)The alarm sounds for three seconds and the warning display blinks for ten seconds,(see page 25) .This warning is recorded in the dive log.24
