First, inspect the O-ring as it is seated in the groove. If any of the following are evident, there is a high chance that the strobe will flood if placed in water. Be very careful about checking these points:
If hair, sand, lint or other debris is attached to the O-ring Remove O-ring and wipe-off the debris.
If the O-ring is cut or cracked
The O-ring must be removed and replaced with a new O-ring. If the O-ring is twisted
The O-ring must be removed and reinstalled uniformly with no twists or other irregularities.
If there is hair, sand, lint or other debris on the O-ring contact surfaces Wipe of any debris.
If there is a scratch, blemish or other imperfection on the O-ring contact surfaces
The strobe must be inspected by an authorized technician, and repaired if possible. Contact Inon or you local Inon distributor for advice.
O-ring Maintenance MethodGrease: Inon O-rings are compounded with a special type of oil that is not compatible with all grease types. Periodically re-grease the O-rings only using the supplied Inon Grease. Do not use any other grease, which may cause the O-rings to swell or deform, causing poor seal and water leakage. Use of non-Inon grease will void warranty.
Field Maintenance: For periodic maintenance in the field it is not necessary to always remove the O-ring and inspect the O-ring groove for each dive. If there is not any sand or other debris visible it is ok to lightly grease the O-ring while it is seated in the O-ring groove. For other maintenance follow the instructions below.
Removing O-ring
If you need to remove the O-ring for replacement, inspection, or to check the O-ring groove etc., lightly squeeze the O-ring from the sides (see figure) so it bulges out from one side. Grasp the extended part and gently pull to remove. Never use sharp or metal objects to remove O-rings as they may damage the O-ring itself or the O-ring groove contact surface. If squeezing the O-ring from both sides does not work, try gently using the edge of a credit card or similar object, to pry the O-ring up a little so you can grasp it. Then clean any
residual grease or debris from the O-ring groove and contact surface, and check the condition
