safety information. This section is provided to improve understanding of these symbols.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol
to avoid possible injury or death.
DANGER
indicates a hazardous situation which, if not avoided, could result in death or serious injury.
WARNING
indicates a hazardous situation which, if not avoided, could result in damage to the product or bodily harm.
CAUTION
indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE
indicates information that relates to the protection of property.
This symbol means read the operator’s manual carefully before using the equipment. The operator’s manual contains important information
on the safe and proper operation of the equipment.
This symbol means always wear safety glasses with side shields or goggles when handling or using this equipment to reduce the risk of eye
injury.

General Notes and Warnings
Do not run this LED Matrix-3 SeaLite outside the
recommended voltage range.
Do not remove the set screws in the collar on the LED
Matrix-3 SeaLite body as these hold the light body and
light head together.
WARNING
After each deployment, carefully check to make sure the
light has not flooded by shaking and listening for water,
or visual inspection for moisture inside the LED window.
Also look into the holes on the forward bracket and
verify the head is tightly mated to the rear housing. It is
possible for some lights to partially flood and then reseal
themselves while underwater. Upon surfacing, the
light would then be internally pressurized, a potentially
dangerous situation. Additionally, if the power remains
on when the light has partially flooded, it is possible
for electrolytic generation of an explosive mixture of
hydrogen and oxygen gases. The Matrix-3 has a unique
design to prevent possible internal pressure buildup in
that the light head assembly will ‘pop’ slightly and relieve
any internal pressures over 100 psi. If the head looks
slightly askew be sure to investigate for possible leaks.
If a light appears flooded upon removal from the water
as evidenced by water or moisture on the inside of the
window, it should be treated as potentially dangerous.
Make sure that the power is disconnected as soon as a
flooded condition is suspected. Point the light away from
persons and valuables.
Corrosion Warning:
The LED Matrix-3 SeaLite is made
from superior strength aluminum alloy 7075 to make it as
lightweight as possible. It has been hard anodized and
fitted with strategically placed sacrificial zinc anodes to
resist corrosion of the body. Be sure to regularly inspect
these zincs for depletion and replace them before they
are fully corroded. These lights are not designed for long
term immersion of more than several weeks. Designers
and end users must employ a system-wide corrosion
prevention scheme that includes this strong, but less
noble metal.
Thermal Warning:
The LED Matrix-3 SeaLite has
thermal protection designed into the LED light engine
and the electronic driver. If the light is operated in air for
an extended period of time the useful life the LED’s may
degrade and the external temperature of the housing
will reach temperatures that may be painful to human
touch. If the light is operated briefly for testing purposes
in air, be sure to let it cool down for a couple of minutes
before immersing it in water to minimize thermal shock
to the components. It is also a good idea to turn the light
off a few seconds prior to removing it from the water as
part of normal recovery procedures, as this will minimize
buildup of scale on the LED window and housing
components.
