ACTION MANUAL

Congratulations on your purchase of a SEAC diving computer.

The SEAC ACTION dive computer is a technologically advanced device designed and manufactured to provide all the information that every diver needs.

Periodically check www.seacsub.com for any updates to this manual.

GENERAL WARNINGS

• WARNING!

Read the user manual fully before using the SEAC computer.

Using the computer incorrectly will void the warranty and can permanently damage the computer.

• WARNING!

Only use the dive computer after you have read all sections of the instruction manual and you have understood how it works.

• WARNING!

The dive computer is not a substitute for diver training and should only be used by divers who have been properly trained and who have earned the appropriate license issued by a Certified Teaching Association.

• WARNING!

The computer does not replace an understanding of decompression tables, which divers must always carry with them for safety, along with a depth gauge and a dive watch.

• WARNING!

The SEAC computer is an auxiliary device during a dive. Therefore, it is crucial that each diver always carry with them a suitable table that will enable them to conduct the decompression phase if the unit should malfunction.

3

• WARNING!

Freediving entails risks of syncope, taravana, pulmonary edema, and hemoptysis, while diving with a respirator involves risks related to decompression sickness, oxygen toxicity, nitrogen narcosis, and in general other risks connected to the dive itself: even a thorough reading of this manual and use of the instrument does not exclude potential dangers.

• WARNING!

The computer cannot take into account individual physiological changes that can change from one day to the next. For this reason it's good practice to use the device conservatively and cautiously, remaining within the limits shown by the computer in order to minimize the risks.

• WARNING!

It is strictly forbidden to freedive in the 12 hours after diving with scuba equipment!

Violating this rule could considerably increase the risk of decompression sickness.

• WARNING!

Do not share one computer between two divers during the dive. Every diver must have their own instrument to provide information and save only that diver's data.

• WARNING!

Before diving, you must check the battery charge. Do NOT dive if the low battery icon is shown on the display. Always check that the display shows no signs of any malfunction and that it is clearly legible.

The Battery icon on the display has 2 segments:

Segment 1: Battery Outline ==> Battery lower than Minimum Voltage (do not dive).

Segment 2: First Bar from the bottom ==> Battery lower than 2.1V (Low level. The voltage could plummet during a dive in especially cold water).

4

ACTION

• WARNING!

Always check that the settings are correct for your dive, and don't allow anyone else to tamper with your computer before the dive. If it has been tampered with by another person, check that your settings are correct.

• WARNING!

It is important to keep in mind that your body undergoes changes, even daily changes, that a computer cannot account for. If your physical condition is not excellent, or if you feel any physical problems, do not dive!

• WARNING!

The normal functions of the product could be disturbed by strong electromagnetic interference.

In this case, simply reboot the product to restore normal function, following the instructions provided in this manual (see “Reset”) and use the product in another position.

• WARNING!

Strictly avoid pressing on the side grill of the sensor with your fingers, especially if the sensor compartment is full of water, because this could distort the measurement of zero, and could therefore result in an incorrect measurement of depth during the next dive, with the consequence that the NDL/Deco data may also be inaccurate.

In DIVE mode, if you notice a measurement of anything other than zero on the surface, you need to reset the device to zero out the sensor measurement (see the instructions and warnings on using the RESET further on in this manual) or wait a few hours for the system to reestablish the correct zeroing.

TECHNICAL CHARACTERISTICS

Dive modes

The computer manages three dive modes:

I. Scuba mode:

Dive: When depth exceeds 150 cm/5 ft.

Emerge:when depth is less than 90 cm/3 ft.

II. Gauge mode:

Dive: when depth exceeds 150 cm/5 ft.

Emerge: when depth is less than 90 cm/3 ft.

III. Free Mode:

Dive: when depth exceeds 100 cm/3.3 ft.

Emerge:when depth is less than 50 cm/1.6 ft.

After a dive in SCUBA / GAUGE mode, the Computer stays on the SCUBA / GAUGE screen for 10 minutes after emerging, and therefore you cannot access the menu and submenu.

After a dive in FREE mode, the Computer stays on the FREE screen for 15 minutes after emerging, and therefore you cannot access the menu and submenu.

After a dive in SCUBA or GAUGE mode, FREE mode is inhibited and is not accessible for the next 12 hours.

After a dive in GAUGE mode, because tissue saturation is calculated assuming that the dive uses mix number 1, SCUBA mode is available.

After a dive in GAUGE mode, the Desaturation and NoFly times are updated with the new tissue saturation data. In particular, the NoFly time is set to 24 hours, as a precaution in favor of safety, regardless of the type of profile that was run.

After a dive in FREE mode, the residual Desaturation and NoFly time, if any existed before the dive in FREE mode, will be left unchanged.

8

ACTION

If you Reset the Settings, the Computer will automatically start in SCUBA mode.

When the Computer is in Watch mode and you dive without manually entering dive mode (using the LR button), the Computer will automatically launch the mode you selected most recently.

Decompression Algorithm

The computer uses the original Buhlmann ZHL-16C Decompression Algorithm, unmodified.

Levels of Protection

The Action allows you to select 6 levels of protection (conservatism), from 0 to 5. Level 5 provides the maximum protection.

Repetitive Dives

All dives taken within a 48-hour period are considered “Repetitive Dives”.

Dives with Surfacing

“Surfacing” is defined as the situation in which the diver emerges after having begun a Scuba type of dive.

Surfacing ends if the diver dives again within a period of fewer than ten minutes from emerging; beyond this limit the current dive is considered ended.

If you change mixes during the dive and dive again within the 10 minute Surfacing time, the mix in use is reset to the starting mix .

NDL - NonDecompressionLimit

The “NonDecompressionLimit” is defined as the time that remains at the current depth and breathing the mix that is currently set to avoid requiring decompression.

To avoid requiring decompression stops, the time required for the ascent must be subtracted from the NDL.

9

Safety Stop

The user can set both the depth and the duration of the Safety Stop.

NOTES:

a) The Safet y Stop is calculated and proposed if the maximum depth reached is

greater than 12 meters/40 ft.

b) The Safety Stop is shown when the diver comes within 9 meters/30 ft of the

surface.

c) The countdown begins if the diver arrives within +2 meters/+6.5 ft and

-2 meters/-6.5 ft of the stop depth set. For example: If the stop set is 5 meters/16.5 ft, the countdown starts between 7 meters/32 ft and 3 meters/10 ft. In this case then, if you go to a depth of less than 3 meters/10 ft., the stop will be canceled.

d) The Safet y Stop is not calculated and is not proposed if at least one deco stop

is underway within 9 meters/30 ft from the surface.

e) If the current dive includes one or more decompression stops, and if these

decompression stops are cleared during the ascent (before reaching 9 meters/30 ft) because of a very slow ascent or in any case a multilevel dive, then the Safety Stop is calculated and proposed at the time and duration set by the user.

f) If the Diver again exceeds a depth of 9 meters/30 ft after having performed

the stop, the Safety Stop is recalculated and reproposed in accordance with the rules described above.

g) If the Diver descends to a depth greater than 9 meters/30 ft during the

countdown, it will be reset and recalculated according to the rules above.

10

ACTION

Deep Stop

If the Deep Stop is enabled, it is calculated as a 2-minute-and-30-second stop at half the maximum depth reached if the following conditions are met:

- Maximum depth reached greater than 18 meters/59 ft.

- There are no mandatory decompression stops during the ascent.

NOTES:

a) The Deep Stop is displayed at +5 meters/+16.5 ft and -3 meters/-10 ft from

the calculated stop. In other words, if the Deep Stop is at 20 meters/66 ft, it is displayed in the range from 17 meters/56 ft to 25 meters/82 ft.

b) The countdown to the stop begins when the diver arrives in a range of +2

meters/+6.5 ft and -2 meters/-6.5 ft from the calculated stop depth. For example: if the stop is calculated at 25 meters/83 ft, the count down is performed in the range of 27 meters/89 ft to 23 meters. If the Diver moves -2 meters/-6.5 ft from the stop depth (meaning lower than 23 meters/75.5 ft), it is canceled. If the Diver arrives within 27 meters/89 ft - 31 meters/102 ft, the countdown is suspended.

c) If the Diver again exceeds the stop depth by more than 6 meters/20 ft (or

in any case, 18 mt/59 ft), the stop will be recalculated according to the rule above.

TTS

The “TTS” is the total time to surface, and accounts for the entire time for executing mandatory decompression stops (calculated according to user settings) and the ascent time (calculated at a constant velocity of 9m/min - 30 ft/min).

11

Ascent Speed Alarm

The standard maximum ascent speed is set at 9 meters/minute - 30 ft/min.

The Ascent Speed Alarm indicates the ascent speed using icons, and is only available in SCUBA mode.

The Ascent Rate icon consists of 3 arrows.

The Ascent Speed Alarm is both visual and audible.

The visual alarm cannot be disabled.

Users can disable the audible alarm.

The rules for the Ascent Speed Alarm are:

- Speed <= 3m/min- 10ft/min: No indication

- 3m/min- 10ft/min < Speed <= 6m/min-20 ft/min: One arrow

- 6m/min -20ft/min < Speed <= 9m/min- 30ft/min: Two arrows

- 9m/min- 30ft/min < Speed <= 12m/min 40ft/min: Three arrows

- Speed > 12m/min – 40 ft/min: Three flashing arrows + Audible alarm

MOD Exceeded Alarm

The “MOD” defines the maximum operating depth for the mix in use and is calculated as a function of the real surface atmospheric pressure and the PpO2 (oxygen partial pressure) set for the mix in use.

The alarm for Exceeding the MOD is visual and audible.

The visual alarm cannot be disabled; this is indicated by the field for the current depth flashing.

Users can disable the audible alarm.

Both alarms are activated as soon as the MOD is exceeded.

12

ACTION

Deco Violation Alarm

The Deco Violation Alarm will trigger when the Diver reaches a depth less than (in absolute value) that set by the mandatory decompression stop.

The Deco Violation Alarm is visual and audible.

The visual alarm cannot be disabled; this is indicated by the field for the current depth flashing.

Users can disable the audible alarm.

Both alarms will trigger when the Diver reaches a depth less than (in absolute value) 0.5 meters/1.6 ft of the mandatory decompression stop indicated.

The alarm does not trigger for Deep Stops and Safety Stops, because these stops are not mandatory.

Locking the Computer

If decompression stops are omitted, rather than immediately switching to lock mode like other dive computers, Action applies penalty points that eventually result in locking the SCUBA mode upon reaching 150 points.

The penalty points are assigned as follows:

- 5 points for every 5 seconds, if the diver's current depth is lower than one meter/3 ft from the stop level indicated.

- 10 points for every 5 seconds, if the diver's current depth is lower than two meters/6.5 ft from the stop level indicated.

This means that for an ongoing violation, Action will enter lock mode after about 2 minutes at a depth lower than one meter/3 ft, and after about 1 minute if the stop depth violation is 2 meters/6.5 ft, naturally only if the violation is occurring in the direction of the surface.

Once it reaches 150 points, the computer switches to lock mode.

The diver will be notified during the dive with an “Alert” icon and a message, alternating with information about remaining decompression, indicated by the words “WARNING DECO VLT”.

Decompression will still be calculated until the end of the dive where anticipated by the Buhlmann mathematical model.

13

• WARNING:

two repetitive dives with surface times of fewer than 10 minutes are considered to be a single dive.

If the mandatory decompression stop is violated during the dive and the computer switches to lock mode, SCUBA mode will not be available for 18 hours.

After this period, the counter to put the watch out of service will be reset at the beginning of the next dive.

If you begin a new dive in SCUBA mode before this interval, when the computer is still in lock mode, the “Alert” icon and the message reading “WARNING DECO VLT” will be displayed for the entirety of the dive, without alternating with the decompression data.

Whenever the computer is locked, the NoFly and Desaturation times are not shown.

No-fly time

NoFly time is calculated according to the following rules:

- 12 hours for a single dive (no dive in the preceding 48 hours) within the nodecompression limits.

- 18 hours for repetiti ve dives without decompression on the same day or multiday.

- 24 hours for repetitive dives with decompression on the same day or multiday.

For more information, consult the "No-fly Time" section in the "After the Dive" chapter.

Desaturation Time

The tissue Desaturation Time is calculated immediately at the end of the dive.

It is defined as the time necessary for the nitrogen inert gas pressure to be lower than the Partial pressure of nitrogen (PpN2) breathed, increased by a tolerance factor.

For more information, consult the "Desaturation Time" section in the "After the Dive" chapter.

14

ACTION

Permitted Altitude Indicator

The Permitted Altitude is calculated and updated after dives as follows:

The Permitted Altitude icon is shown in Watch mode, and is managed as follows:

- Max 1000 m/3290 ft: 1 triangle on.

- Max 2000 m/6580 ft: 2 triangles on.

- Max 3000 m/9870 ft: 3 triangles on.

- No Limit: icon o (not displayed).

Battery/Run-time

The computer is powered by a 3V CR2450 MAXCELL Asia Product battery with a nominal capacity of 600 mAh.

The battery capacity varies based on environmental conditions.

The battery run-time varies depending on how the product is used and which functions are used.

The run-time drops noticeably when backlighting, audible alarms, PC connections, and updates are used.

When the Software Application is launched, a test of the battery under load is performed. When this happens you may notice the backlighting turn on temporarily. If the battery voltage under load is less than 2.0V (Minimum Voltage), the device will remain o or locked, on a screen with the words “LOW BAT ”. In some cases you may see a continuing Reset for a few cycles.

If the battery voltage under load is below 1.8V (Start Voltage), the backlighting may remain on continuously until the computer battery is completely drained. In this case, the computer will not turn on at all and no text appears on the LCD.

The Battery icon on the display has 2 segments:

Segment 1: Battery Outline ==> Battery lower than Minimum Voltage (do not dive).

Segment 2: First Bar from the bottom ==> Battery lower than 2.1V (Low level. The voltage could plummet during a dive in especially cold water).

Time and Time Zones

The computer can handle two time zones:

Local Time:Time at the user's location.

Home Time:The time at home.

The reference time is always the LOCAL time, and is indicated in the center of the Watch screen, or in secondary screens during SCUBA/GAUGE/FREE dives.

The Home time can only be changed by editing the value of the “UTC HOME” time zone in the “SYS SET” menu.

If “UTC LOC” and “UTC HOME” are the same, only one time is shown on the Watch screen.

If the two parameters do not match, the LOCAL Time is shown in the center of the screen (the date indicated refers to this Time), while the HOME time is shown on the lower right.

If the date for each of the two Times is dierent, the date oset from the HOME Time will be shown on the lower right: “+1 / -1”.

ACTION

Planner

Action's Planner lets you simulate and plan a dive, displaying the NDL time (within non-decompression limits) depending on the depth set.

The Planner allows you to plan Air/Nitrox with NDL only, meaning within the non-decompression limits, and therefore requiring no decompression time.

The input data (mix, Max PpO various submenus (“MIX”, “DIVE SET”) and are used to calculate the NDL.

The calculated NDL accounts for descent performed at 18 meters/minute 59 ft/ minute.

The calculated NDL does not include the time required for the ascent.

In Planning mode, you can only change the dive depth and the surface time.

The NDL Time display is updated immediately whenever the dive depth or surface interval is changed.

The Info screen shows:the name of the model, the serial number (which is also laser engraved on the back of the case), and the firmware version installed.

Reset

Resetting tissues and user settings is a risky procedure, especially if the diver is taking repetitive dives. Therefore you have to confirm twice before a reset will be performed:

Enter a four-digit security code. The security code is “5555”.

If the code entered is valid, before performing a reset, you will need to confirm the operation.

If the operation is successful, the message “RESET DONE” will appear.

• WARNING!

On the watch screen, the icon of the “WARNING” symbol will appear on the lower left to alert the diver and remind them that the computer was reset. This symbol will disappear after the next SCUBA/GAUGE/FREE dive.

• WARNING! DANGER!

Do NOT perform the tissue saturation reset if the device will be used soon by the same person!

This can lead to the risk of accidents, including fatal ones.

The tissues can only be reset if the Action will be used by a person who has not taken any dives in the previous 48 hours.

ACTION DURING THE DIVE

• WARNING!

This manual does NOT replace adequate training!

• WARNING:

Before diving, always check that the dive mode has been set correctly for the dive you are about to take (SCUBA-OC, Gauge, or Free) by pressing the LR button from watch mode and checking that the icon showing at the top is the correct one, or you can check and make a selection in the “DIVESET” set.

29

• WARNING!

This check is important, because if you begin a dive in the wrong mode (for example, FREE instead of OC-SCUBA), firstly you will not have the correct information which could compromise your safety if you continue the dive, and even if you resurface immediately you need to wait out the time planned for the end of the dive, meaning 10 minutes for a dive set to SCUBA/GAUGE and 15 minutes for a dive set to FREE.

If you do not switch to dive mode manually by pressing the LR button once from watch mode, the Action will automatically activate dive mode when you descend past 1.5 meters.

SCUBA (OC) DIVE

• WARNING!

This manual does NOT replace adequate training.

• WARNING!

Do not dive with the Action if the battery charge is low, meaning with only Segment 1 lit:Battery Outline ==> Battery lower than Minimum Voltage.

When only the first block from the bottom is lit, this means a low battery charge. Avoid diving in especially cold water, because the voltage could plummet.

AFTER THE DIVE

After a dive in SCUBA / GAUGE mode, the Computer stays on the SCUBA / GAUGE screen for 10 minutes after emerging, and therefore you cannot access the menu and submenu.

After a dive in FREE mode, the Computer stays on the FREE screen for 15 minutes after emerging, and therefore you cannot access the menu and submenu.

After a dive in SCUBA or GAUGE mode, FREE mode is inhibited and is not accessible for the next 12 hours.

After a dive in GAUGE mode, because tissue saturation is calculated assuming that the dive uses mix number 1, SCUBA mode is available.

After a dive in GAUGE mode, the Desaturation and NoFly times are updated with the new tissue saturation data. In particular, the NoFly time is set to 24 hours, as a precaution in favor of safety, regardless of the type of profile that was run.

After a dive in FREE mode, the residual Desaturation and NoFly time, if any existed before the dive in FREE mode, will be left unchanged.

Desaturation Time

The tissue Desaturation Time is calculated immediately at the end of the dive.

It is defined as the time necessary for the nitrogen inert gas pressure to be lower than the Partial pressure of nitrogen (PpN2) breathed, increased by a tolerance factor.

All calculations refer to the atmospheric pressure measured at the end of the dive.

NOTE: When using the DAN Protocol to calculate the NoFly time, for some dive profiles it is likely that the NoFly time will be higher than the Desaturation Time, which might not appear consistent. This is due to the fact that the NoFly time might derive from a protocol and not from an exact mathematical calculation. Therefore, in order to avoid creating confusion for the end user, if the NoFly time calculated at the end of the dive is greater than the Desaturation Time, the algorithm corrects the Desaturation Time so that it is equal to the NoFly time. This calculation is to achieve a higher level of safety.

38

ACTION

No-fly time

Under the DAN protocol, the NoFly time is calculated according to the following rules (Revised Flying After Diving Guidelines for Recreational Diving – May 2002):

- 12 hours for a single dive (no dive in the preceding 48 hours) within the nodecompression limits.

- 18 hours for repetiti ve dives without decompression on the same day or multiday.

- 24 hours for repetitive dives with decompression on the same day or multiday.

Since the scenarios that have been studied are limited and the Dive Computer allows you to assess exactly the load in each individual tissue, the following strategy will be adopted, in favor of safety:

- The NoFly time is calculated according to the Buhlmann algorithm.

- If the time calculated is lower than the time indicated by the DAN protocol, then the time obtained from the DAN protocol is used.

- If the time calculated is higher than the time indicated by the DAN protocol, then the time obtained from the Buhlmann algorithm is used.

The calculation method according to the Buhlmann algorithm will be done using 0.550bar as the cabin pressure. This is the minimum pressure recorded in commercial aircraft.

Special cases:

1. If you have not taken any dive, in any mode, in the previous 48 hours:

a. If you take a dive in GAUGE mode, the NoFly time will be 24 hours.

b. If you take a dive in FREE mode, the NoFly time will not be calculated.

2. If you took a SCUBA dive (of any kind):

a. If you take another dive in GAUGE mode before the NoFly time expires,

after the dive in GAUGE mode the NoFly time will be 24 hours.

Connect your ACTION computer to your Mac or PC

The Action can be connected to your Mac or PC through the DiveLogger program to download dives and run updates.

Updating your Action Dive Computer.

It's very important to keep your Action Dive Computer consistently up to date with the most recent version of the software.

The Action must be connected to a Mac or PC using the USB cable to run the updates.

• WARNING!

If an update is available, a new version of the operating system will be installed.

After every update:

- Check that the Action settings (mix, algorithm, deco stops, etc.) are correct for the next dive.

- After each update, the Action resets the settings and tissues (see RESET in this manual).

After connecting your Action to your Mac or PC using the special USB cable and having set the Action to computer mode, when “PC LINK ON” appears you can start the data transfer.

REPLACING THE BATTERY

• WARNING!

Batteries should always be replaced by an authorized SEAC Center, because this is a delicate operation with a high probability of subsequent flooding of the Action if performed by inexpert personnel.

SEAC declines all responsibility for problems resulting from changing the battery.

• WARNING!

When replacing the CR2450 battery, it's a good idea to also replace the O-ring of the battery cap an original SEAC O-ring.

a) Unscrew and remove the four screws from the battery compartment.

b) Insert a small flathead screwdriver into the special opening located on the

bottom of the cap to lift the lid.

c) If needed, again using the small flathead screwdriver, prize up the battery

from its housing and remove it.

d) Insert the new battery, snapping it into its housing and making sure that

the “+” polarity sign is facing outward.

e) Remove the old O-ring from the housing in the metal cover and replace

it with the new one. Make sure that the O-Ring is not damaged, and once inserted make sure it isn't twisted at any point.

f) Position the cover on the Action case, and press it evenly downward. Make

sure that in the area around the screws, the cover is flush with the case.

g) Keep the cover pressed down on the Action case while replacing the four

screws. Although the four screws are screwed through four metal inserts fixed in the case, we recommend not tightening with excessive force to reduce the risk of stripping. The recommended torque is 12 Ncm. The O-ring seal on the battery compartment is radial, so excessive closing force on the compartment screws is not necessary.

NOTE

Do not dispose of used batteries in the environment or discard them as ordinary waste; we recommend using special battery disposal services.
