Perform Vacuum Analyzation

• Turn on the Vacuum Analyzation and Wet Detection System (VWS) by power on the Multi-control Device, the Signal Indicator will show Blue Blinking or Blue Quick Blinking (once/sec). If it is not operated for more than 10 minutes, the Vacuum Analysis and Wet Detection System will go into standby mode and the Signal Indicator will show Blue Blinking (once/5 sec). Close the Rear Cover according to the steps described in Installing camera into the housing

• Take off the Protection Cap from the Vacuum Valve and connect the Vacuum Pump onto the red colored Vacuum Valve Tip. Pull and Release the Vacuum Pump handle gently and repeatedly for Vacuum Pumping. During the Vacuum Pumping process, check carefully for changes in color on the Signal Indicator (fig. xviii ~ xxi).

• Color Codes Indication:

  • Yellow Quick Blinking Internal pressure has started to drop. Continue to pump.
  • Yellow Slow Blinking Internal vacuum level is close to the desired value. Slow down pumping.
  • Yellow Still | Internal vacuum level has been reached. Stop pumping and the Vacuum Analyzation Process will start automatically.
  • Yellow and Red Blinking alternately Internal vacuum level is above the desired value. Stop pumping and carefully release air by gently twisting the red colored Vacuum Release Tip counterclockwise slightly until the Signal Indicator shows Yellow Still (fig. xxii). If too much air is released from the housing, the Signal Indicator will change back to Yellow Blinking again. Resume vacuum pumping until Signal Indicator shows Yellow Still.
  • The Vacuum Analyzation Process will start automatically once the Signal Indicator shows Yellow Still. Disconnect the Vacuum Pump from the Vacuum Valve carefully and then put back Protection Cap to the Vacuum Valve (fig. xxiii). Do not move or shake the housing or put the housing under the sun when the analyzation process has started.
  • The Vacuum Analyzation Process takes approx. 3 minutes. Once the process is completed, the Signal Indicator will show different color depending on the result:
  • Green Blinking – Vacuum Analyzation passed and Housing is ready to go into the water.
  • Red Blinking – Vacuum Analyzation failed and inspection for the leakage is required. Please re-check all the seals on the housing. Power off the Multi-control Device to reset the system and attempt the Vacuum Analyzation process again.

Perform Water Leakage
Test Once Vacuum Analyzation is completed successfully and Vacuum Valve Protection Cap is secured, review the housing further by checking for water leakage. Submerge it in a shallow water tank. While submerged, activate all the control buttons, control switches, and control knobs in order to have a dynamic test to prove all the sealed moving parts are water sealed property. If there is no water droplet observed inside the housing after Underwater Dynamic Test, it means the housing is fully watertight. If water leaks into the housing, the water droplets will be detected by the Wet Sensor Strip located in the lowest part of the housing. Signal Indicator will show Red Still and 5 Sec audible alarm “BEEP. BEEP-BEEP” will be heard (fig. xxiv).

Using the Housing and Camera after testing passed

• Please ensure that the Vacuum Valve Cap is in place and completely closed.
• When using the housing, make sure that it is properly secured to you and accessories are properly secured to the housing.
• Do not exceed the housing maximum depth rating of 45 Meters (148 ft.) d. If the wet detection alarm is triggered during use, it means water has entered into the housing. If that happens, try to position the housing lens port facing down and exit the water safely in accordance with diving procedure and regulation. Upon returning to land, remove the camera from the housing. If only a few droplets of seawater entered the housing, thoroughly wipe off the seawater droplets with a moist towel and dry the inside of the housing thoroughly with tissue paper. e. If seawater leaked into the housing and the Multi-control Device is flooded, take out the camera, rinse the housing cavity thoroughly with running fresh water for a few minutes. Then, dry the housing cavity completely and bring it to your local dealer for servicing immediately.

Auto Sleeping Mode
When the Multi-control Device is connected to the camera with the Hot Shoe Connector, it will follow to the status of the camera. When the camera is in Sleep Mode, the Multi-control Device will be in Sleep Mode too. When the camera is operational, the Multi-control Device will be operational too.

Connecting the Fiber Optic Cable

•  The housing is built-in with an Optical Flash Trigger in the Multi-control Device. This feature prolongs the camera battery life by not using the built-in camera flash to trigger the external underwater strobe. The housing is equipped with two Fiber Optic Cable Ports and they are compatible with AOl Fiber Optic Cable with SS cable plug or other fiber optic cable brands using the standard Sea & Sea plug

• Insert one end of the fiber optic cable into the Fiber Optic Cable Port of the housing (fig. xxv) and then insert the other end into the fiber optic cable port on the external strobe.

• The flash trigger signals (electrical signals) will be transterred from the camera Hot Shoe to the Multi-control Device through the Hot Shoe Connector (included in the package). The Optical Flash Trigger in the Multi-control Device will convert the electrical tlash triggering signals into optical signals and then will deliver them to the Fiber Optic Cable. The Fiber Optic Cable (not included in package) picks up the optical signais and delivers them to the external strode.

IMPORTANT

• For getting the best result of Flash Triggering, Multi-core Fiber Optic Cable is recommended 1o be used.
•  Rinse the Fiber Optical Cable Ports with running fresh water after every use, then let it dry naturally. Do not dry inside of the ports with any tool, this may result in scratches and reduce the capacity of the optical signal transter.

Care and Maintenance

• Rinse the housing exterior thoroughly with running fresh water after every use. Depress buttons and rotate knobs/dials repeatedly in fresh water to eliminate trapped salt water or debris. Dry the housing and Lens Port with a soft, clean cloth to avoid water spotting and damage.

• To clean the Lens Port Glass, use a mild soap solution or lens cleaner. Do not rinse the inside of port glass. Do not use alcohol or window cleaner on the Lens Port Glass.

• In order to better inspect, position, clean or lubricate the Housing Main Seal O-ring or Lens Port O-rings, carefully remove the required O-ring by using the provided AOl O-Ring Remover.

• Clean the Main Seal O-ring and its O-ring groove by using a microfiber cloth only. Use AOl O-Ring Remover to clean the O-Ring groove. Do not use cleaning substances other than fresh water. Remove sand, dirt, hair or fibers that can prevent a proper housing seal.

• To lubricate O-rings, apply a small amount of silicone grease (AOl SIGR-5) on your fingertips, gently pull the O-ring through the fingertips. This will lightly coat the entire O-ring with silicone grease. Only use the AOl Silicone Grease supplied or those approved by AOl. Using other brands of silicone grease may damage the O-ring. Do not over stretch the O-ring
  Note: DO NOT APPLY Silicon Grease to the Secondary Seal Ring. f. Do not leave the camera and housing in direct sunlight for prolonged periods. Heat may damage the camera and housing.

• Dry well and remove the camera prior to travel and storage. h. Store the housing in a cool and dry place.

IMPORTANT

•  Wipe the housing dry and keep water away prior to opening the housing. Do not allow water to be in contact with the interior of the housing. This will cause irreparable damage to the Vacuum Analyzation and Wet Detection System (VWS) | and other electronic/electrical components! b.
• If you don’t use the housing, please remember to fully charge the battery in the Multi-control Device for every half year.
