4.3 Special note on responsibility for watertight integrity:
Each housing is individually inspected and hydrostatically tested in the factory. The design of the main
piston O-ring seal is among the most reliable in the industry and the watertight integrity is excellent.
This special O-ring design provides a perfect seal even if there is any movement between the body
and lid due to change of ambient pressure. However please note that responsibility for ensuring the
integrity of the watertight seal lies entirely with the user. 10BAR accepts no liability for damage to, or
loss of any equipment used with, or placed inside the housing. Users are highly recommended to
carry out in-water test of the housings without installing of the camera for their first dive after change
of new ports or alternation of any new configuration. The test can be carried out by lowering the
housing with ballast to the working depth or dive down to the safe diving range.
The O-ring seal is the only barrier between the water outside and the air space within the
camera. It is an effective barrier only if the seal is properly maintained. The O-ring seal
should be inspected before every dive. The following information is provided for your
guidance in using and maintaining the O-ring seal.
4.5 Maintaining the O-ring Seal:
If the main body to lid O-ring is not installed, install the O-ring before diving. This is the only user
serviceable O-ring. Its care and maintenance is critical to the watertight integrity of the housing. The
O-ring should be replaced at the service interval (see section on service). If the O-ring is contaminated,
or not already installed, inspect grease and install the O-ring according to the following guidelines.
4.4 Inspection, cleaning and re-instillation of the O-ring
Tools:
A soft cotton bud or sponge applicator, make sure these are free of all chemicals or contamination such
as loose fibers, and the tube of silicone grease supplied with the housing are required. Note other types
of silicone grease specifically for use with underwater camera equipment can usually also be used. It is
advised to carry out the following procedure on a firm clean level surface, (e.g. at a table), to prevent
skidding especially useful to have when diving from a boat.
When to maintain the O-ring seal:
Remove the O-ring periodically for inspection. It is not necessary to remove, clean and re-install the
O-ring after every dive provided the O-ring did not become contaminated. As a rule of thumb set up the
camera and housing before a day’s diving. If the housing is required to be opened between dives for
changing memory card or re-charging batteries, make sure the outside of the housing is thoroughly
toweled dry before opening up. After removing the lid and servicing the camera, replace the lid
straight away, rather than leaving it lying around. Before replacing the lid, make sure that no
contamination such as dust, hair, salt, sand etc. has fallen onto the O-ring or O-ring recess, as a
precaution we recommend to inspect the O-ring every time the lid is opened and to carry out the
maintenance if necessary.

5
Procedure:
Place the lid on a firm non-slip level surface.
The O-ring can be extracted using an O-ring extractor tool (make sure the tool as no sharp edges).
Alternatively use the flats of the thumbs to gently stretch the O-ring on two faces (Fig. 4) thus making
a small loop protruding a few mm. The loop can then be grasped between finger and thumb, to pull the
O-ring over the lip.
• Clean the O-ring recess (the square groove where the O-ring sits) with a cotton bud.
• Inspect the O-ring all the way round its surface for damage such as cuts tears or contamination.
This should be done visually and also by feeling the surface texture between finger and thumb.
IF THE O-RING IS DAMAGED OR SUSPECTED OF BEING DAMAGED, DISCARD IT
IMMEDIATELY. A spare O-ring is supplied with your housing, or a replacement O-ring can be
obtained from 10 BAR. If the O-ring is contaminated or suspected of being contaminated, clean it with
a cotton cloth that is free of all chemicals or contamination. After cleaning inspect the O-ring again.
Once the O-ring has been inspected and verified fit for use, apply a SMALL amount of silicone grease
to the O-ring. The silicone grease must be evenly distributed round the O-ring

Replace the O-ring into the groove; run a finger round the O-ring, to make sure it is snugly seated in
the groove.
(Fig.6) Stretch the O-ring
4.5 Mounting the flashlight in the housing:
Set the flashlight in normal position. Slide the flashlight all the way into the hot shoe of the
housing until it is stop (Fig. 7), Turn the lock ring follow the direction “LOCK”. Take care not to
excessively tighten the screw (Fig. 8). Note: If you find that control levers do not locate properly with
the buttons, please check again that the flashlight is properly seated to the limit of the guide rail.

(Fig. 7) (Fig. 8)
Replace the lid, remember to ensure the pressure release plug is pulled all the way out while
closing, otherwise the air cannot escape. Squeeze the lid closed all the way, you will hear the hiss of air
being expelled.
(Fig. 9)
After replacing the lid, make a final visual inspection of the main O-ring for contamination (Fig. 9)
Note: If the O-ring is in good contact, a thin black line, about 0.5-1mm in width should be
visible, where the O-ring is in contact with the lid. Follow this line all the way round the
edge of the seal, as a final check that the seal is good.
The housing is now ready for the dive.
Important !!! Before diving, make sure the pressure release plug is pushed
back inside and then screwed home, do not over tighten this plug (finger
tight only).

5. Use & Care of Housing
5.1 Pre Dive Function Check.
Just before entering the water, make a habit of reviewing that you have carried out the proper
steps to close the housing and the bulkhead is connected. Make a visual check of the O-ring seal.
It is also useful to switch on the camera, and check that controls e.g. on/off, zoom, shutter
functions operate normally.
 Check housing is closed
 Check O-ring is in the groove between housing and Acrylic
 Check control knob and zoom function.
If there is a large change of temperature and the housing is not opened for
maintenance between dives, it is recommended to equalize the possible pressure
difference between the inside of the housing and the ambient by opening the
pressure release plug and close it firmly subsequently.
Always avoid submerging the housing in hot water for a prolonged time or a cleansing
tank where the water may be heated up by the sun.
5.2 General Operation.
The control levers and push buttons consist of internal double O-ring seals on a stainless steel
shaft. This arrangement is very reliable, however as a precaution, when operating the controls, avoid
excessively rapid movements, as this may distort the O-ring. Also please allow for the fact that the
camera takes a few seconds to power on. If the camera dose not appear to respond to a control action,
make sure that no other controls are pressing on the camera, i.e. locking out further actions. Wear the
wrist strap; it is easy to inadvertently let go of the housing, especially if you are distracted.
5.3.Cleaning & Storage
The body & lid of the housing are made of polycarbonate. Polycarbonate was selected for its
outstanding strength stiffness, hardness and toughness. As well as its crystal clear transparency
and high gloss surface. It has good resistance to weathering, although long-term exposure to
sunlight should be avoided. Normal operating temperature range is 3°C to 36°C (Storage
temperature: -10°C to 50°C)
It is good practice to rinse off your housing with fresh water after every dive. Avoid exposure to
fine sand. After a series of 10 or more dives, e.g. after a dive holiday, it is recommended to
immerse the housing for 2-3 hours in warm water to dissolve any salt deposits that may have built
up. No chemical cleaners should be used. Mild detergents e.g. shampoo and soap based cleaners
are permitted.
Important !!! Some household chemicals may harm Polycarbonate; the housing should never be

8
exposed to the following classes of chemicals:benzene, toluene, xylene, chlorinated hydrocarbons,
methanol, any other solvents, strong acids and bases.
For long term storage please remove the main o-ring from body.
5.4 Transportation.
When transporting by air, please ensure the housing is not sealed, to allow the air pressure to equalize.
Either remove the O-ring (recommended) or store the body and lid separately.
Please protect the housing during transportation. It is recommended to remove the sync cord, and
wrap the housing in foam or bubble wrap.
5.5 Accidents
The impact resistance of the housing is excellent. However after an accident the alignment of
the housing may have been damaged. Therefore in the event of your housing suffering an impact force,
e.g. being dropped, it is essential you do not use the housing for diving. Please return the housing
immediately for service. Please put a note inside to indicate the nature of the accident, so that we can
assess the severity.
6. Service
To ensure the continued performance of your housing, it should be serviced every year, or
after every 200 dives whichever is earlier. Please note the terms for servicing the housing posted
at our website. A full service will include:
 Inspection of all components for wears or damage (report if repair necessary)
 Cleaning of all sealing surfaces, and replacement of all O-ring seals.
 Hydrostatic pressure test to 10 Bar.
Note: the replacement of damaged components (except replacement O-rings) may
require additional cost.
