1. IMPORTANT WARNINGS
1.1 General Warnings
WARNING
This manual must be read and understood entirely before using the product. It is advised
that you keep this manual in your possession during the entire life of your BC. FAILURE TO
READ, UNDERSTAND, AND FOLLOW THE PRECAUTIONS LISTED IN THIS MANUAL
COULD RESULT IN SERIOUS INJURY OR DEATH.
WARNING
When diving you must follow the rules and apply the skills taught by a recognized scuba
diving certication agency. Before taking part in any diving activity, it is mandatory to
have successfully completed a scuba diving course covering both theoretical and
technical aspects of diving.
WARNING
This instruction manual does not replace a diving instruction course!
1.2 Pre-Dive Warnings
WARNING
DO NOT DIVE with a BC that does not pass any of the Pre-Dive, Dive or Post-Dive
inspection points and tests. Diving with a BC that fails any of the listed check points could
result in the loss of buoyancy control while diving, resulting in serious injury or death.
WARNING
In accordance with European standards, our BCs can only be considered certied
where all components are present, as per the original SCUBAPRO conguration,
including the low pressure hose supplied.
Any variation of the original conguration invalidates conformity to European certication
standards.
WARNING
Ensure you have fully understood the jacket’s function and features and adjust the straps
appropriately before diving. If in doubt, ask your ofcial SCUBAPRO dealer for help.
WARNING
Do not attach an L.P. hose to a Scuba regulator high pressure (HP) port or to a gas supply
with pressure in excess of 200 psi (13.8 bar). This may result in damage or explosive failure
of the Ination Valve or Low Pressure Hose, which could result in injury or death.

1.3 Dive Warnings
WARNING
DO NOT DIVE with a BC that is damaged, leaks air or does not function properly. Terminate
any dive as safely and quickly as possible if the BC becomes damaged, leaks gas or does
not function properly.
WARNING
Special instruction in cold water diving practices and the specic use of this product in cold
water is required prior to cold water diving (temperatures below 10°C/50°F). This instruction
is beyond the scope of this manual.
WARNING
This product is designed to use air or helium/nitrogen/oxygen mixtures containing up to 40%
oxygen. Use of gas mixtures with increased oxygen, or the addition of other substances,
may cause corrosion, deterioration, premature aging or component failure of metal and
rubber parts. These actions may result in loss of buoyancy control or air holding integrity of
the BC, resulting in injury or death. Non standard gas mixtures may also present a risk of
re or explosion.
WARNING
The assembly of the system should only be done by a trained person such as an Authorized
SCUBAPRO Dealer to avoid incorrect assembly. After the assembly, a nal inspection must
be performed by an Authorized Dealer. Incorrect installation can cause serious injury or
death.
WARNING
Avoid prolonged or repeated exposure to chlorinated water, such as swimming pools.
Wash your BC immediately after any use in chlorinated water. Chlorinated water can
oxidize fabrics and materials on your BC, thereby shortening the life of the BC as well as
cause colors to fade. Damage and fading from prolonged exposure to chlorinated water is
specically not covered under warranty.
WARNING
Do not use your BC as an assist or ‘’lift bag’’ for bringing objects to the surface. These
objects may be lost during the ascent, creating a sudden increase in buoyancy and loss of
buoyancy control.
WARNING
THIS BC IS NOT A LIFE JACKET OR A RESCUE DEVICE.
Emergency face up oatation may not be provided for all wearers and in all conditions.

6
WARNING
Never breathe from your BC. Your BC may contain gas residue, liquid or contamination that
may result in injury or death if inhaled.
Keep water out of the bladder of the BC. Repeated use of the Oral Valve or Over Pressure
Valve may allow water inside the BC, reducing the amount of buoyancy provided by the BC.
This could result in injury or death. Drain all water out of the BC prior to every use.
WARNING
Wing-style BCs are built for a stable position underwater. The S-Tek is not a life jacket. Fully
inated, the S-Tek does not guarantee an unconscious diver will be in a safe, heads-up
position at the surface.
WARNING
When using a weightbelt with the crotch strap, you must place the weightbelt on top of
the crotch strap ensuring it can fall freely from your body. Failure to follow this practice will
prevent the weightbelt from being released and may result in serious injury or death.
WARNING
Keep sand and other contamination out of the mouthpiece of the TEK BPI. Under certain
conditions, contamination can cause the valve not to close completely. If this occurs
while diving, shake the TEK BPI while depressing the deate button several times. If the
valve leaks or remains inoperable, terminate the dive. Diving with a leaking Buoyancy
Compensator or with valves that do not operate properly may result in a loss of buoyancy
control that could result in injury or death.
WARNING
The deation device with the maximum outow of gas is the lower deation valve (g. 17)

3. PRECAUTIONS
For your protection while using SCUBAPRO life support equipment, we call your
attention to the following:
• Use the equipment according to the instructions contained in this manual and only
after having completely read and understood all instructions and warnings.
• Use of the equipment is limited to the uses described in this manual or for
applications approved in writing by SCUBAPRO.
• Cylinders must only be filled with atmospheric compressed gas, according to
the EN 12021 norm. Should moisture be present in the cylinder, beside causing
corrosion of the cylinder, it may cause freezing and subsequent malfunction of the
regulator during dives carried out in low temperature conditions (lower than 10°C
(50°F). Cylinders must be transported according to local rules provided for the
transport of dangerous goods. Cylinder use is subjected to the laws regulating the
use of gases and compressed air.
• Equipment must be serviced by qualified personnel at the prescribed intervals.
Repairs and maintenance must be carried out by an Authorized SCUBAPRO
Dealer service facility and with the exclusive use of original SCUBAPRO spare
parts.
• Should the equipment be serviced or repaired without complying with procedures
approved by SCUBAPRO or by untrained personnel or not certified by SCUBAPRO,
or should it be used in ways and for purposes other than specifically designated,
liability for the correct and safe function of the equipment transfers to the owner/
user.
• The content of this manual is based upon the latest information available at the
time of going to print. SCUBAPRO reserves the right to make changes at any time.
• All dives must be planned and carried out so that at the end of the dive the diver
will still have a reasonable reserve of air for emergency use. The suggested
amount is usually 50 bars (725 psi).
SCUBAPRO refuses all responsibility for damages caused by non-compliance with the
instructions contained in this manual. These instructions do not extend the warranty or
the responsibilities stated by SCUBAPRO terms of sales and delivery.
