Delayed Violation Mode

Spending more than five minutes above the decompression stop depth.
If you stay shallower than the required decompression stop depth for more than five
minutes, the Matrix enters Delayed Violation Mode (figure 14). Immediately after
entering Delayed Violation Mode, the Compartment Loading Bar Graph starts to flash
and the total ascent time continues to flash (continued from Conditional Violation
Mode). If you descend below the decompression ceiling after 5 minutes, the Matrix
can still assist you in getting back to the surface. Stay at, or slightly below, the
decompression ceiling until you complete the decompression requirement. Once you
clear decompression, remain underwater until the CLBG recedes to well within the
green zone. After five minutes of surface time, the Matrix enters Immediate Violation
Mode and will operate only in Gauge Mode (see page 36).

Decompression stop greater than 40 feet
The maximum decompression stop depth for the Matrix is 40 feet (12 m). As soon as the computer calculates a
decompression stop depth slightly greater than 40 ft. (12 m), the Matrix goes into Delayed Violation Mode. Once
the Matrix enters Delayed Violation, the CLBG will continuously flash.
To get back to the surface safely, you must immediately ascend to, or slightly deeper than, 40 feet (12 m) until the
CLBG stops flashing. Continue to make your decompression stops as indicated by the computer. After you clear
decompression and the CLBG recedes into the yellow zone, continue decompressing until the leading segment is
near, or into the green zone. After five minutes of surface time, the Matrix will enter Immediate Violation Mode for
24 hours.
If you do not make an immediate ascent to the 40-foot (12 m) decompression stop after entering Delayed Violation
Mode, the calculation limits will be exceeded and the computer will enter Immediate Violation and operate only in
Gauge Mode (see page 36) for 24 hours.
Immediate Violation Mode
The Matrix enters Immediate Violation Mode when a dive profile represents gross excursions into decompression that
are beyond the boundaries of the Matrix’s computer model. If you intend to make these types of decompression dives,
you should not be using the Matrix.
Two situations cause the Matrix to enter Immediate Violation Mode:
1. Five minutes after surfacing from a dive in which you entered Delayed Violation.
2. A calculated decompression stop much greater than 40 feet (12 m).

Gauge Mode - Surface (24 to 12 hrs)
While in Immediate Violation Mode, the Matrix makes the following function changes:
1. The Matrix only operates in Gauge Mode (explained in the next section)
2. Pre-Dive Planning Sequence is disabled
3. Wait-to-fly display (from 24 to 12 hours) is disabled
Gauge Mode
After the Matrix has experienced an Immediate Violation, the computer only operates
in Gauge Mode. In Gauge Mode the computer no longer calculates decompression
information. In essence, the computer becomes a depth gauge and bottom timer.

Underwater
When in Gauge Mode underwater (figure 15), the Matrix flashes the CLBG and
only displays current depth, maximum depth, bottom time, and ascent rate .

On the surface (24 - 12 hrs.)
During the first 12 hours on the surface while in Gauge Mode (figure 16),
the Matrix gives you the dive number, depth, and surface time. The Wait-to-
fly display and Pre-Dive Planning Sequence are disabled. The Dive Log
Recall Mode is not affected and can be accessed as described in the
previous chapter.
