3.2.2 MOD/ppO

2



WARNING

- The MOD should not be exceeded.

Disregarding the alarm can lead to

serious injury or death.

- Exceeding a ppO

2

of 1.6bar can lead to

sudden convulsions resulting in serious

injury or death.

When the diver reaches a depth at which the

ppO

2

of the inspired gas exceeds the maximum

limit entered in the corresponding setting

(from 1.2 to 1.6bar), an audible alarm goes

off, the current depth starts to blink and the

message MOD ALARM is shown at the bottom

of the display. In addition, the value of the MOD

is shown to the right of the current depth.

The alarm persists until the diver has

ascended enough for the ppO

2

to return within

the set limit. While the alarm is active, the

compass can only be called up for 8 seconds,

after which the default display with the alarm

message is shown again.



WARNING

When the MOD alarm is triggered, ascend

immediately until the alarm stops. Failure to

do so could result in serious injury or death

.

3.2.3 CNS = 100%



WARNING

When the CNS reaches 100% there is

danger of oxygen toxicity. Start procedure

to terminate the dive.

Oxygen toxicity exposure is tracked on

Matrix by means of the CNS % based on

currently accepted recommendations for

exposure limits. This toxicity is expressed as

a percentage value which ranges from 0%

to 100%. When the value reaches 75%, an

alarm goes off and the message CNS > 75%

appears for 10 seconds. Additionally, once the

text message has expired, the CNS becomes

the default item in the lower right corner:

if you call up other information such as the

temperature or the time of day, after 8 seconds

the CNS appears again. Ascend to shallower

depth to decrease oxygen loading and consider

terminating the dive.

When the oxygen toxicity level approaches

100%, the alarm message CNS > 100%

appears. The alarm message and the audible

signal are repeated for 5 seconds in one-

minute intervals after the ﬁrst occurrence

and for as long as the value of CNS stays at

or above 100%. Consider terminating the dive

immediately!



WARNING

Diving with oxygen toxicity at levels of 75%

or greater may put you into a potentially

hazardous situation, which could result in

serious injury or death.

3.2.4 MISSED DECOMPRESSION STOP



WARNING

Violating a mandatory decompression

obligation may result in serious injury or

death.

If you ascend above the decompression stop

depth by more than 0.3m (1ft), a downward

pointing triangle appears, an audible alarm

goes off and the message STOP AT 3m! or

STOP AT 10ft! is displayed at the bottom of the

screen (or whatever the depth of the stop is).

This alarm remains active until you return to

the correct depth. Note that while the alarm

is active, the compass can be viewed only for

8 seconds before the screen returns to the

default display.



WARNING

- When the missed deco stop alarm is

triggered, desaturation of the simulated

tissue compartments is halted and

resumes only when the diver returns to

the correct stop depth.

- Never ascend above the displayed

decompression stop depth.

3.2.4.1 MISSED DECO STOP MODE

If the stop depth is exceeded by more than 1m

(3ft) for more than three minutes, Matrix

considers it a dive violation and the display will

show

.

In this case, if the diver attempts a repetitive

dive after surfacing, Matrix will function

only as a depth gauge and timer (bottom

timer mode), and it will display the message

LOCKED in the middle of the screen.
