Safety considerations

I UWATEC

Aladin

dive computers

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

PRIME or Aladin

TEC.

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

PRIME or Aladin

TEC.

Guidelines for the use of Aladin

PRIME and Aladin

TEC:

The following guidelines for using Aladin

PRIME and Aladin

TEC 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

PRIME and Aladin

TEC are designed for dives with Nitrox (Aladin

PRIME max.50%O

, Aladin

TEC max.100%O

) and compressed air (21%O

) only. Do not use Aladin

PRIME or Aladin

TEC 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 mix-

ture currently used. Always remember: setting an incorrect mixture carries an inherent risk of decom-

pression sickness and/or oxygen toxicity! Maximum deviation from the measured mixture must not

exceed 1% O

. An incorrect gas mixture can be lethal!

• Only use Aladin

PRIME and Aladin

TEC with open circuit breathing systems. Aladin

PRIME and Aladin

TEC must be set for a determined gas mixture.

• Only use Aladin

PRIME and Aladin

TEC for diving with an independent breathing apparatus. Aladin

PRIME and Aladin

TEC are not designed for long term exposures with Nitrox.

• Always observe the visual and audible alarm signals. Avoid situations of increased risk which are mar-

ked with a warning sign in this operating manual.

• Aladin

PRIME and Aladin

TEC have a ppO

warning. The default limit is set at 1.4 bar ppO

max.

On Aladin

TEC it can be changed between 1.2 and 1.6 bar.

• Frequently check the "oxygen clock" (CNS O

). 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

. Aladin

PRIME and Aladin

TEC give

no warning about this.

• On all dives with Aladin

PRIME or Aladin

TEC

, make a safety stop for at least 3 minutes at 5 metres (15 ft).

• 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

PRIME or Aladin

TEC fail at any time during the dive, the dive must be terminated, and appro-

priate surfacing 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. Aladin

PRIME and Aladin

TEC do not substitute for a dive buddy.

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

PRIME and Aladin

TEC do

not increase your knowledge of diving.

• Always dive with back-up instruments. Make sure that you always use back-up instrumentation inclu-

ding a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and have access

to decompression tables whenever diving with a dive computer.
