Pre-checking before Diving

1. Perform Vacuum Analyzation

a. Power on the Vacuum Analysation and Wet Detection System (VWS), if the Signal An indicator shows Blinking BLUE (1 time/sec), which means the Vacuum Analysis and
The wet Detection Sensor is on standby mode. Close the Rear Cover according to the steps described in “Installing camera into the housing”.
b. Take off the Protection Cap from the Vacuum Valve and connect the Vacuum Pump to the 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 colour on the Signal Indicator.
1. Perform Vacuum Analyzation
c. Colour Codes Indication:
Fast Blinking YELLOW
Internal pressure has started to drop. Continue to pump.
Slow Blinking YELLOW
The internal vacuum level is close to the desired value. Slow down pumping.
Still YELLOW
The internal vacuum level has been reached. Stop pumping and the Vacuum Analyzation Process will start automatically.
Blinking alternate YELLOW & RED
The internal vacuum level is above the desired value. Stop pumping and carefully release air by gently twisting the Vacuum Release Tip counter- clockwise slightly
until the Signal Indicator turns to Still YELLOW. If too much air is released from the housing, the Signal Indicator will change back to Blinking YELLOW again.
Resume vacuum pumping until Signal Indicator turns to Still YELLOW.
d. The Vacuum Analysation Process will start automatically once the Signal Indicator turns Still YELLOW. Disconnect the Vacuum Pump from the Vacuum Valve carefully and then put back Protection Cap to the Vacuum Valve. Do not move or shake the housing or put the housing under the sun when the analysis process has started.
e. The Vacuum Analyzation Process takes approx.4 minutes. Once the process is completed, the Signal Indicator will turn either RED or GREEN, depending on the result:
Blinking GREEN – Vacuum Analyzation passed and Housing is ready to go into the water.
Blinking RED – Vacuum Analyzation failed and inspection for leak is required.
f. In case of a significant air leakage detected anytime during/after the Vacuum Analyzation Process, the Signal Indicator will turn Blinking RED.
g. Below (Table 2) is the summary of Signal Indicator Colour Codes Indication.

Table 2

Blinking Altern
YELLOW – RED| Vacuum above the desired level| Twist the Vacuum Release Tip
counter-clockwise
Still YELLOW| Vacuum analysis in progress| Wait for 4 minutes for vacuum analyzation
Slow Blinking GREEN| The vacuum analyzation test has Passed| Ready for going into water
Blinking RED| Vacuum analysis test has Failed| Inspect the housing for any potential air leakage sources
Steady RED with audible alarm| Wet Sensor Strip detects water droplets or moisture| Inspect the housing for any potential water leakage sources

2. Perform Water Leakage Test
Once Vacuum Analysation is completed successfully and Vacuum Valve Protection Cap is secured, review the housing further by checking for water leakage. Submerge it in a shallow tub of water or rinse 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 properly. 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 turn Still RED and audible alarm “BEEP-BEEP-BEEP” will be heard.

Using the Housing and Camera after testing passed

a. Please ensure that the Vacuum Valve Cap is in place and completely closed.
b. When using the housing, make sure that it is properly secured to you and accessories are properly secured to the housing.
c. Do not exceed the housing maximum depth rating of 60 meters (200 ft.)
d. If the Wet Detection alarm is triggered during use, it means water has entered the housing. If that happens, try to position the housing lens port facing down and exit the
water safely in accordance with diving procedures and regulations. 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 leaks 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.

Connecting the Fiber Optic Cable

a. You can install Olympus Flash FL-LM3 or AOI LED Optical Strobe Trigger STR-04 on the camera hot shoe and use either one for the external Slave Flash(es) triggering.
b. This housing is equipped with two Fiber Optic Cable Ports and they are compatible with AOI Fiber Optic Cables with SS cable plug or other fiber optic brands using the
standard of Sea & Sea plug.
c. Insert one end of the fiber optic cable into the Fiber Optic Cable Port of the housing (fig. xvii) and then insert the other end into the fiber optic cable port on the external
flash or strobe.

IMPORTANT:
a. Check the compatibility of the Filter Optic Cable and multicore fiber optic cable is recommended and preferable.
b. When you use Olympus Flash FL-LM3 and use only one side of the Fiber Optic Cable Port, the other blank out Fiber Optic Cable Port must be closed by a Fiber Optic Plug
(included in housing accessories). Otherwise, the flashlight will emit out from the blank
c.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 transfer.

Care and Maintenance

a. Rinse the housing exterior thoroughly with running fresh water after every use.
Depress buttons and rotate knobs/dials repeatedly in freshwater to eliminate trapped saltwater or debris. Dry the housing and Lens Port with a soft, clean cloth to avoid
water spotting and damage.
b. 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.
c. 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 AOI
O-Ring Remover/White Balance Card.
d. Clean the O-ring and the O-ring groove by using a microfiber cloth only. Use AOI
O-Ring Remover/White Balance Card to clean the O-Ring groove. Do not use cleaning substances other than freshwater. Remove sand, dirt, hair or fibers that can
prevent a proper housing seal.
e. To lubricate O-rings, apply a small amount of silicone grease (AOI 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 AOI Silicone Grease supplied or those approved by AOI. Using other brands of silicone grease may damage the O-ring. Do
not over-stretch the O-ring.
f. Do not leave the camera and housing in direct sunlight for prolonged periods. Heat may damage the camera and housing.
g. 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 Analysation and Wet Detection System (VWS)
and other electronic/electrical components!
