Safety considerations

UWATEC® Smart dive computers

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

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 the computer!

Guidelines for the use of your UWATEC dive computer:

The following guidelines are derived from the latest medical research and the recommendations of the

American Academy of Underwater Sciences for diving with diving computers. Following these guide

lines will greatly increase your safety while diving, but cannot guarantee that decompression sickness or oxygen toxicity will not occur.

• This computer is designed for dives with Nitrox (to a max.100% O

) and compressed air (21%O2) only.

Do not use the computer 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 this computer with open circuit breathing systems. The computer must be set for a determined gas mixture.

• Only use this computer for diving with an independent breathing apparatus. The computer is not designed for long term exposures with Nitrox.

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

• If the ascent arrow appears, start to ascend.

• If the flashing ascent arrow appears, start to ascend immediately.

• This computer has a ppO

warning, the default limits of which are set at 1.4 bar ppO2max. This limit

can be adjusted via SmartTRAK. An alteration of the ppO

max to higher than 1.6 bar is dangerous and

we do not recommend this.

• Frequently check the "oxygen clock" (CNS O

), especially in the range higher than 1.4 bar ppO2.

Ascend and finish the dive if the CNS O

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

. The computer 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 the computer 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 ft) 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 (30 feet) 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. Smart Z does not substitute for a dive buddy.

• Only make dives that are appropriate to your level of dive training. A dive computer does not increase your knowledge of diving.

WARNING

Safety considerations

UWATEC® Smart dive computers

• 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).

• 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 this com

puter! 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%.

• 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 microbubble warning

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.

Altitude and diving

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

• After a dive do not rise to altitudes that the computer prohibits via the flashing altitude

segments (see page 25).

Flying after diving

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

II System and operation

UWATEC® Smart dive computers

1 System description

Smart Z displays all important dive and decompression data and comes with a unique receiver

which can receive tank pressure data from a transmitter. Mounted at the high pressure (HP) outlet of the regulator, the transmitter measures the tank pressure and radio transmits the information to Smart Z. UWATEC's specially patented transmission process prevents interference and ensures continuous and reliable reception. Smart Z has a data memory which stores the dive data. The data can be transmitted with an infrared interface (IrDA) and the SmartTRAK software to a Windows

personal computer. The SmartTRAK CD software is included with the Smart Z Package. Infrared interfaces are available in PC stores. A list of recommended interfaces is available on the UWATEC homepage (www.uwatec.com).

2 Operation

On page 5 you will find an operating schematic.

2.1 Operating elements

Smart Z has 4 operating contacts B, E, +, – on the outside of the housing. For manual operation, touch base contact B and any one of the other three contacts above the display with moistened fingers («bridging» contacts).

Contact B: Base contact, which has to be touched for all operations.

Contact E: Enter contact. It serves to switch on Smart Z and to confirm or

enter the displayed value. It is therefore comparable to the ENTER or RETURN key of a keyboard.

+ / – Contacts: These allow to navigate between menus and, once inside a menu, to increase or decrease the indicated value.

2 Operation

2.3 Switching on the display

• automatically, on submerging in water or when adaptation to atmospheric

pressure is necessary;

• manually, by bridging contacts on housing (B-E).

• When Smart Z is in state of rest no information is displayed but the atmospheric pressure is continuously monitored. If a higher

altitude range is detected, Smart Z switches on for

3 minutes automatically -> 25.

• Smart Z switches on by bridging the contacts B and E. All segments light up for 5 seconds.

Afterwards the display shows the selected O2 mix, the

temperature and in certain circumstances an altitude range

->25.

If the transmitter is switched on and located within trans

mitting distance, the tank pressure is displayed, otherwise "---" will be displayed. If no transmitter has been paired yet, the display will be blank.

If there is a remaining saturation due to the last dive or

change of altitude, Smart Z also displays the remaining desaturation time, the oxygen toxicity and the "no-fly time"

->24.

2.4 Checking the battery capacity

After switching on Smart Z you can check the battery capacity by bridging the contacts

B and E. The remaining capacity is displayed for 3 seconds as a percentage. If the value reaches 0%, the battery warning gets activated (->17)

and the battery has to be replaced by an authorised SCUBAPRO UWATEC dealer. For a 7-day diving vacation Smart Z uses between 2 – 5 % of its battery capacity.

2 Operation / 3 SOS mode

3 SOS mode

Activation: automatic If the diver remains above a depth of 0.8m (3 feet) for more than three minutes without observing a prescribed decompression, the computer will automatically switch into SOS mode after the dive. The display shows the "SOS" sign and the remaining length of the SOS mode. The dive will be entered in the logbook with "SOS". Other than that the SOS mode has no further impact on the displays and functions on the surface.

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

Once in the SOS mode, the computer will lock up and will be inoperable as a diving instrument for 24 hours.

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 the SmartTRAK software.

2.6 Active backlight

The display of Smart Z can be illuminated both on the surface and underwater. The backlight can be activated by pressing on top of the case. The light will turn off automatically after 8 seconds or after the time selected via SmartTRAK. The backlight can only be activated if the computer display is on.

2.7 Switching off the display

On the surface Smart Z switches off automatically after 3 minutes without operation.

WARNING

4 Setting up Smart Z (transmitter and dive computer)

4.1 Mounting of transmitter

The transmitter is mounted at the high pressure (HP) outlet of the regulator’s first stage before the first dive.

Use air and Nitrox components in accordance with the law of the country.

Procedure:

The transmitter is best mounted laterally on the regulator.

It is advisable to mount the transmitter on the same side that the computer is located. This is the optimal position for transmission.

Do not hold the transmitter by its plastic part.

Mount the transmitter at the HP oulet. If the threads do not match, you can get a fitting adaptor at your diving equipment retailer.

Tighten the transmitter by means of a size 3/4" wrench.

Position of the transmitter for left handers.

Position of the transmitter for right handers.

Position of the transmitter for left handers, if there is no connection possible on the left hand side.

Position of the transmitter for right handers, if there is no connection possible on the right hand side.
