A5: 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 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 flash is not used for a long time, remove the O-ring from the flash, 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 maximum level of 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.

Q6: What are the important points for the flash maintenance?

A6: Please observe the following items. Never use the following chemicals for cleaning, corrosion protection, repair or other purposes:

• Never use alcohol, thinner, benzene or similar volatile organic solvents or chemical detergents to clean the flash. Pure water or lukewarm water is sufficient for cleaning.

• Do not use anticorrosion agents on the metal parts. The metal parts are made of aluminum, brass or stainless steel. Cleaning with pure water is sufficient.

• Do not use adhesive for repairs or other purposes. When repair is required, please contact your local service station or dealer.

Q7: Please tell me about repairs.
