DANGER: NEVER ascend above a de-
compression depth. To avoid this situa-
tion, you should ascend to a depth slightly
deeper than the stage decompression
depth requirement. You should consider
the amount of gas needed to successfully
complete all decompression requirements.
During rough sea conditions, it may be dif-
ficult to comply with the decompression
stage requirements without exceeding it.
Cressi recommends that the shallowest
depth (nearest the surface) be at depth of
about 20 ft., even though decompression
will take slightly longer. Leonardo will auto-
matically calculate this.
Omitted Decompression stage alarm
(im. 23)
If the decompression stage is missed by surfa-
cing 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. In the opposite case, that is
when the diver goes below under the stage
depth by a specific amount, an arrow flashes,
indicating that it is necessary to go up. The
computer allows a maximum time of 2 minu-
tes to correct this dangerous situation; during
this time, the alarm will keep sounding. In the
event that the diver does not descend to the
proper depth (after 2 minutes) Leonardo en-
ters the ERROR PROGRAM. The "STOP" icon
flashes and the instrument won't be usable for
the next 48 hours. The only functions working
