Precautions on Handling the O-ring

This product is kept watertight by the O-ring. To keep the O-ring functioning properly, please observe the following. Improper handling of the O-ring could cause flooding.

CAUTION

• SEA&SEA products use blue O-rings. These O-rings are impregnated with silicone oil through a special process. The lubricating effect of the O-ring lasts as long as the silicone oil is gradually seeping out from within.
• For the maintenance of these blue O-rings, make sure to use genuine SEA&SEA silicone grease (O-ring grease for use with the blue O-rings that comes in tubes with blue lettering and blue caps). If you use silicone grease from other companies or SEA&SEA’s own silicone grease that comes in tubes with black lettering and black caps, the grease you apply will be sucked into the blue O-rings due to their special characteristics, which will result in insufficient grease. If this happens even once, the O-ring will not revert to its normal state and must be replaced.
• If the grease is insufficient, the O-ring will not slide, and it will become harder to open and close the waterproof parts. Because of this, it could become impossible to open or close the housing or it could cause flooding, so please refrain from using the housing with insufficient grease.

Are there any scratches or cracks in the O-ring?
Check the O-ring to make sure there are no scratches or cracks. If there are, replace the O-ring with a new one immediately. When handling the O-ring, do not use pointed metal objects, which could damage the O-ring.
Be careful about dust, sand, and hair
Check the O-ring to make sure that there is no dust, sand, or hair on the O-ring, in the O-ring’s grooves, or on the O-ring’s contact surfaces. If any of these things are attached, remove them completely. If used as is, these things could cause flooding.
Coat with silicone grease
Silicone grease protects the O-ring from chafing. After checking the O-ring to make sure that there are no scratches, dust, or debris, apply a light coating of silicone grease to the entire O-ring with your finger. Applying too much grease will make it easier for dust and debris to adhere to the O-ring, and could cause flooding.

Do not twist the O-ring
When fitting the O-ring into the O-ring – groove, insert it straight into the groove; do not bend or twist it.

Remove the O-ring for inspection before each use
In principle, the O-ring should be removed before each use so that the O-ring, O-ring groove, and O-ring contact surfaces can be checked. This is because you cannot find any sand or debris that may have gotten into the O-ring groove if the O-ring is not removed. For routine maintenance prior to each use, it is advisable to make sure to remove the O-ring.
Be careful about how you store O-rings
When storing spare O-rings or O-rings that you have removed from the housing, keep them in a cool place out of direct sunlight. Also, when storing O-rings, do not place heavy objects on them or twist them.
O-rings last for one year
Although it depends on how well they are maintained, how often they are used, and how they are stored, O-rings generally last for one year. It is advisable to inspect them before use, and replace them early.

Maintenance and Storage

CAUTION

•  After each use in salt water, make sure the battery and connector caps are attached, then in a watertight condition soak it sufficiently in fresh water.

• Insufficient soaking causes damage by salt to the product. Salty residue may be left on the product where it will crystallize as it evaporates. Crystallized salt is hard to dissolve and difficult to remove once formed, and may also result in water leakage.

• After rinsing, dry the product well with a soft dry cloth, then let the prosuct dry in the shade, out of direct sunlight.

• Do not dry the product by heating (using a hair dryer, for example). Heating can deform and damage the product.

• If you do not use the product for an extended period of time, store it away from high temperatures, high humidity, direct sunlight, or extreme cold.

• Always remove batteries from the product after use.

• After using the product, maintain the 0-rings before storing. Examine the 0-rings before and after each dive. We recommend exchange of the 0-rings at least once a year. • Every two years we recommend a complete overhaul of 0-rings regardless of the frequency in use, for the best performance of the product.

• If you do not use the product for an extended period of time, periodic maintenance will keep internal electronic parts from deterioration. Once a month, install batteries and fire a test flash. While the READY/TTL lamp is ready to fire, set the mode switches to [OFF], then remove the batteries. In addition, operate all other swithes as you would in normal operation.

Troubleshooting

Please confirm the following items. If conditions do not improve even after the following has been confirmed, please contact the World Customer Service Center or an authorized SEA&SEA dealer.
READY/TTL lamp does not light up

• Did you insert the batteries? (P.E-17)
• Did you insert the batteries the right way? (RE-17)
• Did you make sure not to use any old batteries? (PE-17)
• Has the battery cap been closed properly? (RE-17)
• An internal protective circuit is activated if the product begins emitting light continuously. If this occurs, turn off the power supply, and put the product in a cool place for a while.
• An internal protective circuit is activated if the product is left in an area with high temperature. If this occurs, put the product in a cool place for a while.
• If the product emits the FULL emission of light for more than 20 continuous bursts, an internal protective circuit will be activated to prevent the reflector in the strobe from overheating, and the strobe will be placed in standby mode (with the READY/TTL lamp lights out) for at least 20 seconds. If this occurs, allow the strobe to cool naturally for at least ten minutes.

The target light does not turn on

• Was the target light button held down for the proper length of time? The target light may not turn on if the switch is held down for too short a time. Press and hold down the target light switch for one second. (RE-13)

Using the Sync Cord
The strobe does not fire

• Is the sync cord connected properly? (P.E-19)
• Is there any rust on the metal pins of the connector? If there is any rust or damage found, please contact the World Customer Service Center or an authorized SEA&SEA dealer.

Using the Fiber-optic Cable
The strobe does not fire

• Is the fiber-optic cable connected properly? (PE-21)
• Does the built-in flash/main strobe on the camera fire? (RE-24)
• When there is a sync cord connected, fiber-optic connection is disabled even if there is a fiber-optic cable connected to the unit. To use the strobe with the fiber-optic cable connection, remove the sync cord. (P.E-19)

The strobe emits light in manual photography mode, but images are dark

• Does the firing mode for the built-in flash/main strobe on the camera match the firing mode on the YS-D3? (P.E-24)
• For details, please refer to the “Customization” section of the YS-D3 DUO introduction page on our website.

When photographs are taken in DS-TTL II mode, the captured images are too bright or too dark

•  Is the fiber-optic cable connected properly? (RE-21)
• Is the light level control dial in DS-TTL II mode set at +/- compensation? (P.E-13)
• For details, please refer to the “Customization” section of the YS-D3 DUO introduction page on our website.
• There may not be any effect obtained from compensation with the light level control dial depending on the shooting conditions and camera settings.

The power will turn off automatically

• The auto power-off mode is turned on. When turning on the power again, set the mode switch to [OFF] before setting it to the desired mode. (P.E-13)
