Decompression - Talis IQ-1201 Benutzerhandbuch

DECOMPRESSION

Decompression mode activates when theoretical No Decompression time and depth limits (NDLs) are exceeded.
Upon Entry into Deco, the Audible will sound until acknowledged or 10 seconds. While it is sounding, the UP Arrow icon, Stop
Bar icon, and full NiBG will flash to alert you.
Deco Entry, information includes (Fig. 63):
> TAT** (hr:min) with Deco mode icon (wave/clock/profile/stop bar), stop bar flashing until the audible is silenced.
> Stop Depth required with FT (or M) and STOP icons.
> Stop Time (hr:min) required with clock icon.
> Tank icon, Gas in use (1 or 2).
> Current Depth with FT (or M) icon.
> UP Arrow icon, flashing until you ascend to within 10 FT (3 M) below the Stop Depth indicated, then it will be removed.
> Full NiBG, flashing during the Audible, then solid.
> ASC while ascending.
• S (< 2 sec) - to acknowledge/silence the Audible.
• L (press) - to activate the Backlight.
**TAT represents Total Ascent Time which includes time required for all deco stops plus vertical ascent time to the surface.
NOTE: Upon entry into Deco, the Deep and Safety Stop features are disabled for the remainder of
that dive, even if No Deco status is regained.
Managing Decompression Stops
To fulfill your decompression obligation, you should make a safe controlled Ascent to a depth slightly deeper than, or equal to,
the Stop Depth indicated and decompress for the Stop Time indicated.
The amount of decompression credit time that you receive is dependent on Depth, with slightly less credit given the deeper you
are below the Stop Depth indicated.
Deco Stop Main, information includes (Fig. 64):
> TAT (hr:min) with Deco mode icon (Stop bar solid).
> Stop Depth with FT (or M) and STOP icons.
> Stop Time (hr:min) with clock icon.
> Tank icon, Gas in use (1 or 2).
> Current Depth with FT (or M) icon.
> Full NiBG, solid.
• A (< 2 sec) - to view ALT screens (similar to those for DS).
• M (2 sec) - to access the Gas Switch Routine.
• S (< 2 sec) - to acknowledge/silence alarms.
• L (press) - to activate the Backlight.
CONDITIONAL VIOLATION (CV)
If you ascend shallower than the calculated Deco Stop Depth, the Audible will sound until acknowledged or 10 seconds.
> While above the Stop Depth no off gassing credit will be given.
> If you descend below the Stop Depth before 5 minutes have elapsed, operation will continue to function in Deco and off gas-
sing credit will resume.
> If you remain above the Stop Depth for 5 minutes, operation will enter Delayed Violation.
CV Main, information includes (Fig. 65):
> TAT (hr:min) with Deco mode icon (stop bar flashing).
> Stop Depth with FT (or M) icon and STOP icon (flashing).
> Stop Time (hr:min) with clock icon.
> Down Arrow icon (flashing).
> Tank icon, Gas in use (1 or 2).
> Current Depth with FT (or M) icon.
> Full NiBG, solid.
• A (< 2 sec) - to view ALT screens (similar to those for Deco).
• M (2 sec) - to access the Gas Switch Routine.
• S (< 2 sec) - to acknowledge/silence alarms.
• L (press) - to activate the Backlight.
