2. Advance Check of the Case

Advance test before use

This Case has been the subject of thorough quality control for the parts during the manufacturing process and thorough function inspections during the assembly. In addition, a water pressure test is performed with a water pressure tester for all products to confirm that the performance conforms to the specifications. However, depending on the carrying and storage conditions, the maintenance status, etc., the waterproof function may be damaged.

Before diving, always perform the following advance test and the water leakage test after installation of the camera.

Advance Test

1.Before installing the digital camera in the Case, immerse the empty Case to the intended water depth to confirm that there is no water leakage.

2.Main causes of water leakage are as follows.

The O-ring has not been installed.

A part of the O-ring or the entire O-ring is outside the specified groove.

O-ring damage, cracks, deterioration or deformation.

Sand, fibers, hair or other foreign matter sticking to the O-ring, the O-ring groove or the O-ring contact surface on the front lid.

Damage to the O-ring groove or the O-ring contact surface on the front lid.

When closing the Case, check for catching of the hand strap and silica gel after the above causes have been eliminated.

CAUTION : ??? The most suitable method for checking water leakage is to immerse the Case to the intended water depth. When this is difficult, water leakage also can be checked at a shallow depth with no water pressure. Do not feel that this is troublesome, but perform this test.

???If the advance test should show water leakage with normal handling, stop using the Case and contact your dealer or an Olympus service station (listed on the rear page of this instruction manual).

E-18

3. Install the digital camera.

After visually checking that dirt has been removed from the O-ring, checking for attached sand and other foreign matter, as well as for damage and cracks can be done by squeezing the entire circumference of the O-ring lightly with your fingertips.

E-30

Using a clean cloth free of fibers, dirt, etc., a piece of lint-free tissue paper or a soft toothbrush, remove any foreign matter attached to the grooves of the O-rings. Also remove sand and dirt particles attached to the O-ring contact surfaces on the case.

CAUTION : ??? When a mechanical pencil or a similar other sharp object is used to remove the O-ring or to clean the inside of the O-ring groove, the Case and the O-ring may be damaged and water leakage may be caused.

???When the O-ring is checked with the fingertips, take care not to stretch the O-ring.

???Never use alcohol, thinner, benzene or similar solvents or chemical detergents to clean the O-ring. When such chemicals are used, it is to be feared that the O-ring will be damaged or that its deterioration will be accelerated.

E-31

Install the O-ring.

Confirm that no foreign matter is attached, apply a thin coat of the accessory grease to the O-ring, and fit the O-ring into the groove. At this time, confirm that the O-ring does not stick out from the groove.

How to Apply Grease to the O-ring

Apply the

1exclusive lubricant to each O-ring.

Spread the

2lubricant all over the O-ring.

Check that the

3O-ring is free of scratch or unevenness.

Apply lubricant on

4the O-ring contact surface.

Make sure that your fingers and the O- ring are free of dirt, and squeeze about 5 mm of lubricant onto a finger. (5 mm is the most appropriate amount.)

Surround the lubricant with three fingers and spread it over the ring. Be careful not to use excessive force as this may stretch the O-ring.

After spreading the lubricant, check visually and by touch that the O-ring is not scratched and that its surface is flat. If it is damaged in any way, replace it with a brand-new O-ring.

Use the lubricant remaining on the fingers to clean and lubricate the case's contact surface.

CAUTION : ??? Always perform maintenance of the waterproof function even when the Case has been opened to exchange the battery or the image storage during shooting. Neglecting this maintenance may become the cause of water leakage.

???When the Case is not to be used for a long time, remove the O-ring from the groove to prevent deformation of the O-ring, apply a thin coat of silicone grease, and store it in a clean plastic bag or the like.

???When drying is done with salt attached, it is likely that a function impairment will be caused. After use, always wash off any salt.

E-32

Maintenance of the threaded sections on the

TTL cable and TTL cable connector

If the threaded sections used to connect the TTL cable to the TTL cable connector are not maintained properly, salt and other seawater residue may adhere the TTL cable and prevent it from being disconnected.

After use in seawater, clean off any salt, sand, or other residue as soon as possible, then dry the equipment thoroughly. Clean the threaded sections with a cotton swab and apply a thin, uniform layer of O-ring silicon grease (provided with this case).

Clean and apply O-ring silicon grease to these sections.

Maintenance of the TTL Connector Cap

After removing the TTL connector cap from the waterproof cap, be sure to clean and grease the O-ring.

Use the waterproof cap maintenance adapter to remove the O-ring unit from the waterproof cap.

E-33

1Insert the adapter by aligning its pin with the hole on the cap.

2Turn the adapter counterclockwise to remove the O-ring unit.

3apply silicon grease to the O-ring. Then, re-attach the O-ring to the O-ring unit.

7. Appendix

Q & A on the use of the PT-022

Q1 : Which digital cameras can be used?

A1 : The PT-022 is only for the models C-760 Ultra Zoom/C-770 Ultra Zoom.

Q2 : What cautions must be observed when loading the digital camera into the Case?

A2 : Pay special attention to the following items when loading the camera into the Case.

(1)Check that the remaining capacity of the battery in the digital camera is sufficient.

This should be checked as the LCD monitor is used under water, and the battery consumption becomes faster.

(2)Check the remaining number of pictures on the image storage.

Please use a card with a sufficient remaining number in order to reduce the number of times the Case has to be opened and closed.

(3)Remove the strap from the digital camera.

When the camera is loaded without removing the strap, the strap may get caught when the Case is sealed and this will cause water leakage.

(4)Before sealing the Case, confirm that the O-ring has been installed properly in the groove in the rear lid of the Case.

(5)Confirm that the O-ring and the O-ring contact surface on the front lid are free of dirt, hairs, and other foreign matter.

(6)Insert the silica gel for defogging. Please use silica gel for the Olympus Case.

(7)Finally install the special balance weight to the tripod mounting thread.

Q3 : What cautions must be observed when using and storing the Case?

A3 : Pay special attention to the following items.

(1)When the O-ring contact surface is pressed strongly from the outside of the Case, or when the Case is twisted, the waterproof function may be impaired and water leakage may be caused.

(2)When the Case is used, left or stored at the following locations, defective operation or trouble may be caused. Always avoid such locations.

(a)Places where the Case can reach high temperatures under direct sunlight or in a car, places with extremely low temperatures, and places with extreme temperature variations

E-35

(3)In case of the following handling with a camera loaded into the Case, trouble or breakage may be caused for the Case and/or the loaded camera. Always avoid such handling.

(a)Hitting other objects

(b)Dropping

(c)Placing heavy objects on top of the Case

(4)When the Case is not used for a long time, trouble from formation of mold etc. may be caused. Before use, confirm the operation of all operation parts and perform the advance test and the final test.

Q4 : What cautions must be observed when opening and closing the Case?

A4 : Pay special attention to the following items.

(1)Do not open and close the Case at locations with water spray or sand spray.

(2)Wipe off all waterdrops from the gap between the front lid and the rear lid and around projections and recesses such as the buckles. When this is not done, entry of waterdrops into the Case is to be feared at the time of opening and closing.

(3)When opening the Case, take care that no water will drip from your hair or body into the Case or onto the camera.

(4)When the Case is open, check that there is no attachment of sand, fibers or other foreign matter to the O-ring and the O-ring contact surface on the front lid.

(5)Do not touch the camera or the image storage with your hands to which sea water is sticking.

(6)If you should detect waterdrops or other signs of water leakage while shooting, immediately end the dive, perform the water leakage test again, and confirm that there is no leakage. If the camera is wet, wipe off any moisture and check the operation.

Q5 : How should the Case be handled after use?

A5 : After use, take out the camera as soon as possible and wash the Case with pure water. In case of use in the ocean, it is effective to immerse the Case for a certain time in pure water to remove any salt. Operate the buttons and levers under water to turn the shafts and wash off any salt. After washing, use a dry cloth without any salt on it to wipe off any moisture and dry the Case in the shade. Do not use hot air from a hair drier or the like and do not dry the Case under direct sunlight. Exposure to high temperatures or direct sunlight may cause deformation, discoloration or breakage of the Case and deterioration of the O-ring. Wipe the inside of the Case with a soft cloth not causing any fibers. Remove the O-ring, wipe off any salt, sand, dust, etc., and also clean the O-ring groove and the O-ring contact surface in the same way and then

E-36

dry them. When an object with a sharp tip is used to remove the O-ring from the groove, the O-ring may be damaged and water leakage may be caused. Always use the accessory pick for O-ring removal.

Q6 : How should I take pictures under water?

A6 : Please observe the following items for shooting under water.

(1)Fix the case with the accessory hand strap to your wrist.

(2)When you place a finger onto the lens window, the finger will appear in the photo. Pay attention to the position of your fingers when holding the Case.

(3)When pressing the shutter lever, hold the Case securely with both hands and operate the lever quietly to prevent camera shake.

(4)Look through the LCD monitor window on the rear of the Case to confirm the picture and then press the shutter lever. Please note that the viewfinder cannot be used, When the LCD monitor is used, the battery is exhausted earlier. In order to avoid losing shutter chances due to an exhausted battery, please always replace a battery with a fully charged battery before each dive.

Q7 : How can I check for water leakage?

A7 : For confirmation, perform the advance test and the final test after loading the camera. The advance test with immersing the Case without the camera to the intended use depth to check for water leakage is the most accurate test, but when this is difficult, it is safer to perform this test even at a depth of 1 m or in a bathtub. The final test also can be performed in a bathtub or a bucket.

Q8 : What are the causes for entry of water?

A8 : The main causes for the entry of water are shown below. Please check them most carefully.

(1)Forgetting to install the O-ring

(2)The O-ring is partly or completely outside the groove.

(3)Damage, deterioration, or deformation of the O-ring

(4)Sand, fibers, hair or other foreign matter on the O-ring

(5)Sand, fibers, hair or other foreign matter on the O-ring groove or the O- ring contact surface

(6)Catching of the strap, the bag of silica gel, etc. at the time of sealing the Case

(7)Throwing the Case from a boat into the water, jumping with the Case into the water, or other sudden application of strong forces onto the Case. When entering the water, hand the Case over quietly or avoid impacts in other ways.

Q9 : What are the important points for O-ring maintenance?

A9 : Please observe the following items.

(1)Never use alcohol, thinner, benzene or similar organic solvents or chemical detergents to clean the O-ring. When such chemicals are used, it is to be feared that the O-ring will be damaged or that its deterioration will be accelerated.

(2)Use the original Olympus silicone O-ring grease (white cap). The grease attached to Cases up to PT-008 (red cap) and the grease of other companies are not suitable for this silicone O-ring, and use of such grease may cause deterioration of the surface and impairment of the waterproof function.

(3)In order to avoid deformation of the O-ring when the Case is not used for a long time, remove the O-ring from the Case, apply a thin coat of the special grease, and store the O-ring in a clean plastic bag. For reuse, confirm that the O-ring is free of damage and cracks, that it has sufficient elasticity, that the surface is free of stickiness and other abnormalities, and use it after applying a thin coat of the special grease. Excessive application of grease does not improve the waterproof function or the permissible withstand pressure. However, it may facilitate attachment of sand, dirt, etc.

A thin, uniform coat produces the best result.

(4)The O-ring is a consumable product. Replace it at least once a year.

(5)Deterioration of the O-ring is accelerated by the use conditions and the storage conditions. Replace the O-ring immediately by a new one if it shows signs of damage, cracking or loss of elasticity.
