DECOMPRESSION WARNING ALARM.

Every time the time available within decompression, shown on the display by the NO DECO icon,

decreases to 3 minutes, Giotto warns the diver by making the digits with the remaining minutes flash

together with the word NO DECO and simultaneously emitting a sound alarm. In this situation, the no

decompression limits are being reached and a decompression dive is required.

DEEP STOP.

In order to avoid the risks related to the micro bubbles formed during the ascent, Giotto is able to suggest

a DEEP STOP of one or two minutes (in case of decompression dives) at variable depth depending on the

dive profile. During the dive, if the profile requires it, DEEP STOP is displayed and an acoustic signal is

issued. The stop icon with the depth and the time minutes is displayed. In case the dive omits the Deep

Stop, the warnings will be deleted and the computer recalculates the ascent planning without that stop.

REMARK: Verify that the deep stop is enabled (see paragraph DIVE SET)

REMARK: In this case, the maximum depth can be displayed by pressing the right (>) button.

DIVING OUTSIDE THE NO DECOMPRESSION LIMITS

DANGER: do not use this device to dive beyond the no decompression limits! Cressi discourages the use

of this device for decompression dives.

However, if during the dive, due to negligence or emergency, you have exceeded the no decompression

limits, Giotto will provide specific information related to a correct ascent and to the decompression

information.

Upon violating the limits, the computer will issue an audible alarm and the screen on the display will

change to look as indicated in the following picture providing the diver with the following information:

1) Stop icon with the word DECO showing that the no decompression limits have been violated and that

decompression must be performed. The arrow indicating UP will flash.

2) Depth of first decompression stage (the deepest), indicated in metres (m) or feet (ft). This can vary from

a maximum of 24 m to a minimum of 3 m by steps of 3 m in 3 minutes.

3) Duration in minutes for the first decompression stage (the deepest).

4) TOTAL icon, indicating the total ascent time, that is the time required to ascend to the deepest stage,

respecting the ascent rate, PLUS the stop time at that depth and any other subsequent stop (indicating the

deep stop if necessary), PLUS the safety stop time, PLUS the time required to reach the surface after

completing the decompression stages.

5) “DIVE.T” icon giving the total time spent while diving.

REMARK: In this case, the maximum depth can be displayed by pressing the right button.

REMARK: In case the deepest stage is a Deep Stop, by pressing the right key you will see, always on the

right top corner, the depth and duration of the first stage, not Deep Stop.

DANGER: NEVER ascend above a decompression depth.

To avoid this situation, you should ascend at a depth slightly below the recommended decompression stop

depth.

Please remember that under these conditions, the amount of air you need to complete your dive increases.

Omitted decompression stage alarm.

If, by any reason, the decompression stage is "forced" by surfacing above the depth given by the

computer, an alarm will sound and the down arrow of the decompression icon will flash on the display until

the diver descends back to the proper depth or below it. The computer allows a maximum time of 2

minutes to correct this dangerous situation, clearly marked by a continuous acoustic alarm. After 2 minutes

without the diver descending to the proper depth, Giotto enters in the ERROR PROGRAM making the

“STOP” icon flash. It will not be possible to use the device for the subsequent 48 hours. The only function

working will be the clock and it will be possible to access the Logbook and History Later, in the PRE DIVE

screen the "STOP“ icon will start flashing, together with the word DECO and the stop icon with the arrow

up flashing. This means that the decompression stage was omitted during the last dive. The LOG BOOK

will store the same warning, indicating that on a specific date, the dive with a specific number was carried

out without the decompression stage.

DANGER: under these conditions you won't be able to dive for the next 48 hours.
