I Safety considerations
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 SUBGEAR 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
guidelines 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
(21%O ) 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% O
• 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
This limit can be adjusted via Dive.Log. An alteration of the ppO
dangerous and we do not recommend this.
• Frequently check the "oxygen clock" (CNS O
Ascend and finish the dive if the CNS O
• 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
surfacing procedures (including a slow ascent and a 3 to 5 minute safety stop at 5 metres /15
ft) should be initiated immediately.
