Safety considerations

I UWATEC Aladin TEC 2G

You must carefully read and understand this entire manual before using your

Aladin TEC 2G

Diving has many inherent risks. Even if you follow the instructions of this manual in a careful manner, it is still possible that you may be seriously injured or die from decompression sickness, oxygen toxicity or some other inherent risk of scuba with Nitrox or compressed air. Unless you are fully aware of these risks and are willing to personally accept and assume responsibility for those risks, do not use

Aladin TEC 2G

Guidelines for the use of Aladin TEC 2G:

The following guidelines for using Aladin

TEC 2G are derived from the latest medical research and the recommendations of the American Academy of Underwater Sciences for diving with diving computers. Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness or oxygen toxicity will not occur.

• Aladin TEC 2G is designed for dives with compressed air (21% O2) and Nitrox (22 to 100% O2) only. Do not use Aladin TEC 2G for dives made with other mixed gases.

• It is absolutely necessary to check the set mixture before each dive and to compare it to the gas mixture currently used. Always remember: setting an incorrect mixture carries an inherent risk of decompression sickness and/or oxygen toxicity! Maximum deviation from the measured mixture must not exceed 1%O2. An incorrect gas mixture can be lethal!

• Only use Aladin TEC 2G with open circuit breathing systems.

• Only use Aladin TEC 2G for diving with an independent breathing apparatus. Aladin TEC 2G is not designed for long term exposures with Nitrox.

• Always observe the visual and audible alarm signals. Avoid situations of increased risk which are marked with a warning sign in this operating manual.

• Aladin TEC 2G

has a ppO2 warning. The default limit is set at 1.4bar ppO2 max. It can be changed

between 1.2 and 1.6bar.

• Frequently check the "oxygen clock" (CNS O2). Ascend and finish the dive if the CNS O2 exceeds 75%.

• Never dive deeper than the Maximum Operating Depth (MOD) pertinent to the gas mixture in use.

• Always check the diving limits considering the oxygen content and standard sports diving procedures (decompression sickness, oxygen toxicity).

• In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 40 metres/130 feet.

•

The danger of nitrogen narcosis has to be taken into consideration

. Aladin TEC 2G gives no warning

about this.

• On all dives, with or without dive computer, make a safety stop for at least 3 minutes at 5 metres (15 feet).

• All divers using dive computers to plan dives and indicate or determine decompression status must use their own computer, which they take with them on all dives.

• If Aladin TEC 2G

fails at any time during the dive, the dive must be terminated, and appropriate surfac-

ing procedures (including a slow ascent and a 3 to 5 minute safety stop at 5

metres /15 feet

) should

be initiated immediately.

• Comply with the ascent rate and carry out any decompression stop required. If the computer should fail for any reason, you must ascend at a rate of 10m (30ft) per minute or less.

• On any given dive, both divers in a buddy pair must follow the most conservative dive computer for that particular dive.

• Never dive without a buddy. Aladin TEC 2G

does not substitute for a dive buddy.

• Only make dives that are appropriate to your level of dive training. Aladin

TEC 2G

does not increase

your knowledge of diving.

• Always dive with back-up instruments. Make sure that you always use back-up instrumentation including a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and have access to decompression tables whenever diving with a dive computer.

• Avoid repeated ascents and descents (yo yo diving).

WARNING

English

I UWATEC Aladin TEC 2G

• Avoid repeated heavy workload while at depth.

• Plan the dives to be shorter if they are made in cold water.

• After finishing the decompression or at the end of a no-stop dive, the final stage of the ascent should be as slow as possible.

• You MUST be familiar with all signs and symptoms of decompression sickness before using Aladin TEC 2G! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the effectiveness of treatment and the delay between the onset of symptoms and the treatment for decompression sickness.

• Only dive with Nitrox after you have been thoroughly instructed by a recognised institution.

Repetitive dives

• Do not start your next dive before your CNS O

% status has dropped below 40%.

• When diving with Nitrox, make sure your surface interval is long enough (just like diving with compressed air). Plan for a minimum surface interval of two hours. Oxygen, too, needs sufficient time to leave the body.

• Match gas mixture to the intended dive.

• Do not attempt a repetitive dive if the no-dive warning NO is visible on the display.

• Plan a day without diving once a week.

• If you have to change computers, wait at least 48 hours before carrying out your next dive.

• Diving after a reset of the remaining saturation (reset, see page 47, or battery replacement, see page 51) may lead you into

potentially

hazardous situations which could result in death or serious

injury. After a reset of the remaining saturation do not dive for at least 48 hours.

Altitude and diving

• Do not dive at altitudes higher than 4000m (13000ft).

• After a dive do not rise to altitudes that Aladin TEC 2G

prohibits via the flashing altitude

range number (see page 29).

Flying after diving

• After diving, wait at least 24 hours prior to flying.

Aladin TEC 2G

dive instrument is a personal protective equipment in compliance with the essential safety requirements of the European Union directive 89/686/EEC. RINA SpA, Via Corsica 12, I-16128 Genoa, notified body no. 0474, have certified the conformity with the European Standard EN 13319:2000.

Important remarks concerning signal words and symbols

Congratulations on purchasing Aladin TEC 2G

and welcome to UWATEC. From now on you will enjoy the assistance of the most extraordinary dive computer - equipped with UWATEC's most innovative technology - while diving.

Aladin TEC 2G

enables you to use two different gas mixtures during the same dive. However, for an easy reading this manual mainly refers to dives with a single gas mixture. Information for diving with two gas mixtures is marked with or has been summarised in special chapters.

We thank you for choosing Aladin TEC 2G and we hope you will enjoy safe dives in the future! Further information on UWATEC dive computers and other products by UWATEC can be found on our web page at www.scubapro-uwatec.com. To make this manual easier to read we will use the term "Aladin" as an abbreviation for "UWATEC Aladin TEC 2G diving computer" throughout this booklet.

Safety considerations Dive computers provide divers with data; they, however, do not provide the knowledge how this data should be understood and applied. Dive computers cannot replace common sense! You must therefore carefully read and understand this entire manual before using your Aladin.

Downloading your dives

Aladin’s memory allows you to store approximately 25 hours of dive profile information in 4 second sampling intervals. With SmartTRAK you can transfer this information to the PC in order to visualize and analyze your dives on the monitor. To download data from Aladin, click on "NEW" under the "LOGBOOK" menu to open and name a new logbook or open an existing logbook. Then click on the "TRANSFER DIVES" icon: a box will appear on the screen identifying the computer being downloaded, and a progress bar will show the status of the transfer. You can choose between transferring all dives or new dives only (default setting) from Aladin’s memory. If you choose to transfer new dives only, SmartTRAK will only transfer dives that are more recent than the most recent dive already saved in the PC logbook. To transfer all dives, you must change the default setting by selecting "Transfer" under "Dives" in the main menu bar.

Once the data is downloaded, a window will show you a summary table of all dives; for the selected dive, another window will show you its details. From these windows you can add and edit your dive information.

WARNING

Bar graph interpretation

2.9 Checking the battery condition

From the

time of day display you can check the battery condition by pushing

2x or 3 x (depending on whether there is desaturation time left).

Aladin displays the estimated remaining battery performance for 5 seconds as

a bar graph. If the bar graph shows 3 segments the battery warning appears

->19 and the battery has to be replaced ->51.

• If the bar graph shows 2 segments, the battery symbol will blink, on the surface and in dive mode, to alert the diver of a dangerous situation: the battery may not have enough energy to finish a dive.

• Replace the battery when the steady battery symbol appears (3 segments)!

The temperature influences the battery performance. In cold water it is lower than in warm water. If the battery shows 4 segments on the surface, it is possible for it to drop to 3 segments during the dive. If this is the case, the backlight will be temporarily disabled. See below.

Aladin

marks dives started with 3 or less segments in the logbook with the

battery symbol.

Logbook information is not lost even when the battery is removed for a long

time.

Activation: automatic If the diver remains above a depth of 0.8m (3ft) for more than three minutes without observing a prescribed decompression stop, the computer will automatically switch into SOS mode after the dive.

Push to see the "SOS" sign and the remaining length of the SOS mode. The dive will be entered in the logbook with "SOS".

The SOS mode will be unlocked after 24 hours.

While in SOS mode, the computer cannot be used for diving. The computer can however be used in gauge mode ->30. All segments in the nitrogen loading bar will flash throughout the dive.

Diving within 48 hours after the end of an SOS mode will result in shorter no stop times or longer decompression stops.

• Serious injury or death may result if a diver does not seek immediate treat

ment should any signs or symptoms of decompression sickness occur after a dive.

• Do not dive to treat symptoms of decompression sickness!

• Diving in SOS mode is extremely dangerous and you must assume full responsibility for such behaviour. UWATEC will assume no liability.

A diving accident can be analyzed at any time in the logbook and downloaded to a PC by means of the infrared interface (IrDA) and SmartTRAK software.

Keeping the backlight permanently on represents a severe strain on the battery. In warm waters (20 °C/68 °F and above), a new battery can sustain 20-40 1-hour dives with the backlight always on. In cold waters (4 °C/40 °F and below) the low battery warning may come on within the first dive. For temperatures between 4 °C/40 °F and 20 °C/68 °F the life of a new battery will be somewhere between 1 and 20 1-hour dives. Aladin monitors the battery level throughout every dive, and if the available energy drops below the warning threshold, Aladin will automatically disable the backlight to prevent a computer shut down.
