USING OPTICAL CONNECTORS
This Aquatica housing can be supplied with optical type strobe connection:
Version –OPT is fully optical, having dual optical type of connection. Included is one (1) dual adapter for typical straight
cord used by INON and various other optical sync cords manufacturers and two (2) Sea & Sea/Olympus type of angled
cord plug, select the desired connection and install on the optical port base, tighten the set screw into place with the supplied
hexagonal wrench.
Version –HYB is supplied with one optical and one Classic Nikonos type of strobe connectors. As well as the Nikonos
electrical connector, Included is one (1) dual adapter for typical straight cord used by INON and various other optical sync
cords manufacturers and one (1) Sea & Sea/Olympus type of angled cord plug, select the desired connection and install
on the optical port base, tighten the set screw into place with the supplied hexagonal wrench.
To use optical triggering, the built-in flash of the camera need to be in the up position, this can be
done at time of installation or later by pressing the flash actuator button (# 15) to release it.
If ambient light images need to be taken simply push the flash actuator lever ( #14) to close the
internal flash.
Note: it is advisable to turn the camera and external strobe off when travelling to your dive site to
avoid useless drain of the camera and strobes batteries.
NOTE: Field testing has shown that mixing brands of optically triggered strobes is unlikely to give
reliable TTL results, therefore it is suggested that when mixing different makes of strobe, that they
be used in manual mode.
On the –HYB version, installing the hot shoe will disengage and prevent the built in flash of the
camera from coming up when needed. Tuck the hot shoe and its ribbon wire safely away from the
path of the built in flash. Always confirm the raising and lowering of the built flash before entering
the water and do test exposure to insure that everything is operating as it should.

MAINTENANCE OF HOUSING AND PORTS
When changing ports or O-rings, a simple seal test without the camera inside should be performed. Strapping a weight to the housing
and lowering the unit to a depth of 30 to 50 feet of water for at least 10 minutes will assure you that the seating of the new port or o-ring
is proper. This test, though time consuming and often considered unnecessary, may save your camera equipment from irreparable water
damage. The housing is now ready for the dive.
CAUTION: Never jump into the water with the housing. It is best to have the system handed to you after you have made your entry,
or have it lowered to you on a rope. Make certain that ropes of other equipment stay clear of the system. Never handle the housing by
grabbing the port or if using one, the Aqua View Finder, make sure that boat staffer are familiar with this procedure and advise them to
manipulate only by using the grips provided with the housing.
When replacing the main sealing O-ring, place the entire O-ring over the O-ring groove and start by pushing the O-ring in the corners.
Work your way around the O-ring making sure it is snugly sitting in the groove. Avoid going solely in one direction as doing so will
stretch the O-ring material and possibly prevent it from properly seating.
CARE AND MAINTENANCE
TO SERVICE O-RINGS OF THE HOUSING, PORTS AND EXTENSION RINGS
1. Removing an O-ring: Never use a sharp instrument when removing an O-ring as this may damage the sealing surface of the groove
or the O-ring itself. A dedicated O-ring tool, a dull pointed object or the edge of a credit card usually works well.
2. Once removed, the O-ring should be inspected for damage. Carefully check that it is free of nicks or cuts and that it retains its original
round profile. O-rings that appear to be damaged should be immediately replaced with new ones and the damaged one permanently
discarded.
3. Rinse the O-ring with fresh water and dry it with a clean lint free cloth.
4. Clean the O-ring groove (the channel where the O-ring sits) with a cotton swab. Be sure to remove any lint the cotton swab may
leave behind. Inspect the groove for damage.
5. Wipe the matching sealing surface part of the housing with a clean lint-free cloth.
