SCREEN CONNECT MANUAL

Congratulations on your purchase of a SEAC diving computer.
The SEAC Screen Connect dive computer is a technologically advanced device designed and manufactured to provide all the information that every diver needs.

WARNING!
The complete user manual can be downloaded for free from www.seacsub.com

GENERAL WARNINGS

• WARNING!
  For your safety and in order to use the product correctly, download the complete user manual from www.seacsub.com and read it in full before using the SEAC computer.
  Periodically check www.seacsub.com for any updates to the complete Screen Connect user manual.
• WARNING!
  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, a pressure 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.
• 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).
• 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.

SWITCHING ON THE SCREEN CONNECT

If your Screen Connect was switched off in OFF mode (Factory mode), press both buttons at the same time to restart it.
Screen Connect has a system that automatically turns off the display after it is idle for 3 minutes. To restart it, press either of the two buttons.

HARDWARE

APPLICATION SOFTWARE

TECHNICAL CHARACTERISTICS

Dive modes

1. Scuba mode:
   Dive: when depth exceeds 150 cm/5 ft. Emerge: when depth is less than 90 cm/3 ft.
2. Gauge mode:
   Dive: when depth exceeds 150 cm/5ft. Emerge: when depth is less than 90 cm/3 ft.
3. Free Mode:
   Dive: when depth exceeds 100 cm/3.3ft. Emerge: when depth is less than 50 cm/1.6ft.

• 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.
• 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 R 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 Screen Connect allows you to select 6 levels of protection (conservatism), from 0 to 5. Level 5 provides the maximum protection.

Battery/Run-time

• The computer is powered by a 3 V 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.
• 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).
• Theoretical run-time, linked strictly to the quality of the battery installed:

• The data indicated above:
• refer to a new battery of recent manufacture (and therefore not subject to excessive auto-draining);
• refer to use at 25°C/77°F;
• refer to use that does not entail direct exposure to sunlight;
• do not include consumption by backlighting and audible alarms or Bluetooth; assume each dive to be a total duration of 60 minutes.

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 Screen Connect 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.

• Unscrew and remove the two screws from the battery compartment.
• Insert a small flathead screwdriver into the special opening located on the bottom of the cap to lift the lid.
• If needed, again using the small flathead screwdriver, prize up the battery from its housing and remove it.
• Insert the new battery, snapping it into its housing and making sure that the “+” polarity sign is facing outward.
• 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.
• Position the cover on the Screen Connect case, and press it evenly downward. Make sure that in the area around the screws, the cover is flush with the case.
• Keep the cover pressed down on the Screen Connect case while replacing the two 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.

SCREEN CONNECT SERIAL NUMBER
The Screen Connect serial number is engraved on the back of the case and can also be viewed on the display in the “INFO” function along with the version of the firmware installed.

CE CERTIFICATION
The Screen Connect is compliant with EC Directives.
The EU Declaration of Conformity is available at: www.seacsub.com

CARE AND MAINTENANCE

• Keep your computer clean and dry. Do not expose the computer to chemical agents, including alcohol. Use only fresh water to clean your computer, removing all saline deposits. Leave the computer to dry naturally; do not use jets of hot or cold air. A jet of pressurized air hitting the pressure sensor could damage it irreparably.
