Safety.stop.(Ss); Decompression - Aeris A300 CS Operating Manual

SAfETY STOP (SS) MAIN, information includes (Fig. 45A/B):
> BATT icon - green (if battery voltage is good), or yellow (if at warning level), or red (if at alarm level).
> Current Depth with FT (or M) icon.
> Graphic SAFETY STOP with Stop icon (arrows and bar).
> Stop Depth with FT (or M) icon & countdown Time (min:sec); or graphic RT with Run Time counting up from 0:00 to 9:59
(min:sec).
> Graphic GAS 1 (or 2, 3, 4), one in use.
> Pressure with PSI (or BAR) icon, if the Receiver and Transmitter are active, flashing when Link is lost; or graphic SPG.
> Air Time Remaining (min) with icon, up to 99 (remains at 99 when greater), blank if SPG.
> TLBG (TL).
• A (2 sec) - to access Adjust Brightness.
• A (< 2 sec) - to access SS ALT (similar to No Deco ALT).
• M (2 sec) - to access the Gas/TMT Switch Menu*.
• M (< 2 sec) - to apply a snapshot Earmark to the PCI data recorded at that time. The graphics EARMARK APPLIED will be
displayed in place of Stop information for 3 seconds (Fig. 46).
• S (< 2 sec) - to restore screen Brightness from the Auto Dim level to the % level you last adjusted it to.
• S (< 2 sec) - to acknowledge alarms; this will also restore screen Brightness if it was dimmed by Auto Dim.
• S (2 sec) - to access Compass*.

DECOMPRESSION

Decompression mode activates when theoretical No Decompression time and depth limits are exceeded.
Upon entry into Deco (Fig. 47), the Audible will sound for 10 seconds* during which the graphic DECO ENTRY (red) will flash.
A Stop Bar with Up Arrow icon (red) will also flash until within 10 FT (3 M) of and below the required Stop Depth (the Stop Zone)
which is also displayed with the required Stop Time (both red).
*S (< 2 sec) - to silence the Audible during the 10 seconds.
> Once within 10 FT (3 M) of and below the required Stop Depth (the Stop Zone), the full Stop icon (Up & Down Arrows with
Stop Bar) will be displayed solid (yellow).
Managing Deco Stops
To fulfill your decompression obligation, you should make a safe controlled Ascent to a depth slightly deeper than, or equal to,
the required 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.
You should stay slightly deeper than the required Stop Depth indicated until the next shallower Stop Depth appears. Then, you
can slowly ascend to, but not shallower than that indicated Stop Depth.
DECO STOP MAIN, information includes (Fig. 48A):
> BATT icon - green (if battery voltage is good), or yellow (if at warning level), or red (if at alarm level).
> Current Depth with FT (or M) icon.
> Graphic DECO STOP with Stop icon (arrows and bar).
> Stop Depth with FT (or M) icon and countdown Time (min:sec).
> Graphic GAS 1 (or 2, 3, 4), one in use.
> Pressure with PSI (or BAR) icon, if the Receiver and Transmitter are active, flashing when Link is lost; or graphic SPG.
> Air Time Remaining (min) with icon, up to 99 (remains at 99 when greater), blank if SPG.
> Full TLBG (TL), red indicates that status is Deco.
• A (2 sec) - to access Adjust Brightness.
• A (< 2 sec) - to access ALT.
• M (2 sec) - to access the Gas/TMT Switch Menu*.
• M (< 2 sec) - to apply a snapshot Earmark to the PCI data recorded at that time. The graphics EARMARK APPLIED will be
displayed in place of Stop information for 3 seconds (Fig. 48B).
• S (< 2 sec) - to restore screen Brightness from the Auto Dim level to the % level you last adjusted it to.
• S (< 2 sec) - to acknowledge alarms; this will also restore screen Brightness if it was dimmed by Auto Dim.
• S (2 sec) - to access Compass*.
DECO STOP ALT, information includes (Fig. 49):
> TAT = hr:min (up to 9:59).
> EDT = hr:min (up to 9:59).
> MAX D = xxx FT (or xx.x M).
> TIME = hr:min with AM (or PM) if 12 Hour Format.
> TEMP = xx F (or C).
> GAS 1 (or 2, 3, 4) = AIR; or FO2 % set with PO2 Alarm setting.
> PO2 = x.xx (current level).
> O2 SAT = xx % (current level of saturation).
• A or M (< 2 sec) - to step back to Main.
• Revert to Main in 10 sec, if no button is pressed.
