Decompression Stop Violation
During your ascent on a decompression dive,
as you approach your decompression stop the
countdown timer will start 0.5m below your
decompression stop depth, and a DECO stop
violation warning will start 1m above your
decompression stop depth, giving you a de-
compression stop depth range of 1.5 meters,
or about 5 feet.
For example, as you ascend on a decompression dive with a decompres-
sion stop slated for 6m, your countdown timer will start when you reach
6.5m. If, during your stop, you drift upwards as much as 1m, the deco stop
violation alarm will activate.
That means for the successful completion of your decompression stop you
would need to stay between 6.5m and 5m in depth.
• When your current depth is shallower than the indicated depth for a
decompression stop, the [ ↓ DOWN] warning is shown.
• DECO will blink and an audible alarm will sound for 6 seconds.
• This warning will continue to sound until you get back to the right depth
for your decompression stop, and will be recorded in your Z1's dive log.
NOTE: Always stop for decompression at the indicated depth. Do not stop
at a shallower depth than indicated. If ocean conditions do not allow
stopping at the indicated decompression depth, try to make your stop 1 to
2 meters deeper (3 to 6 feet) than the indicated depth, and make the stop
for 1 to 2 minutes longer than the indicated time.
By ignoring a decompression stop warning you increase your risk of de-
veloping decompression sickness. In such an event, after 3 minutes your
Z1 will not be able to be used for diving for the next 48 hours. DECO and
current time will continue to blink, indicating that the Z1's functions are
locked.
