Test and prepare flash
3
Turn ON/OFF switch on top of flash to "ON" (When orange flash-ready light is on,
turn switch to TEST. This will test fire the flash. Count the seconds from firing to
when the flash-ready light comes on again. If more than 12 seconds passes,
replace the batteries. Keep the O-rings absolutely clean and dry. (Regular
Alkaline 4 AA batteries will yield about 100 flashes.)
To replace batteries, remove battery compartment cover as described on page 6.
Replace all 4 batteries with Alkaline or NiMH type batteries. NiMH recycle time
and life depends on mAh rating of the battery. A 2100 mAh battery will last longer
and recycle faster than a regular Alkaline battery. There are also newer high-
energy Alkalines available that will have longer battery life than regular Alkalines.
Always keep the battery compartment door O-ring clean, dry and free of
obstructions. Make sure to re-attach the black spacer piece inside the
compartment. Close compartment and latch. Make sure o-ring is completely and
evenly seated in the housing.
NOTE:
Inspect O-ring for cuts, tears, dirt or other damage. Clean or replace as necessary.
Do not grease O-ring. Clean O-ring with fresh water and allow to dry.

If using SeaLife 3X close-up lens,
make sure to aim flash down
towards the subject. For 8X and 16X
lenses, aim flash towards end of
macro wand. Position the flash so
one of the light sensors is to the side
or above the camera (fig. A) and that
the shine of the camera's built-in
flash can trigger the sensor. The
Flash Sensors on the bottom of the
External Flash should not be
positioned behind the camera (fig. B).
The reflection of the camera's built-
in flash must hit one the sensors at
the bottom of the flash head. This
will trigger the flash. There should
be no obstruction on this path, such
as your hand.
