3 LAYERS OF PROTECTION FOR YOUR SAFETY AND CONVENIENCE
The Backscatter Macro Wide 4300 has 3 layers of protection for the bat-
tery compartment seal: 2 main body o-rings and a sand seal gasket.
MAIN BODY O-RINGS
The 2 main body o-rings are identical so there is no worry about mixing
the o-ring up or installing in the wrong order.
To maintain the o-rings, the o-rings need to be removed and inspected
for any dirt, sand, hair, or any other debris and cleaned. Clean the o-rings
with a lint free paper towel to remove any debris and excess o-ring
grease.
Never use petroleum based cleaners, lubricants (such as WD-40), or
chemicals to clean the light or the o-rings as this can damage the light
and o-rings and destroy the water sealing capability of the o-rings.
After the o-rings are cleaned and inspected for any damage, lightly
grease the o-rings with the provided o-ring grease. Do not over grease
the o-rings as excess grease will attract debris to the o-ring. Use just
enough grease to provide lubrication so that the o-ring slides through
your fingers easily. Do not use other types of o-ring grease as other types
of grease may be incompatible with the o-rings and destroy the water
sealing capability of the o-rings, leading to damage of the light.
SAND SEAL
The sand seal is a gasket that will help prevent sand and other debris
from the ocean environment from reaching the o-rings. This helps keep
the o-rings clean and reduces the amount of o-ring maintenance that
needs to be done. The sand seal is not a water tight seal, and is not
designed to keep water out of the light. Never add any o-ring grease to
the sand seal as this will attract sand and debris to the sand seal. To clean,
simply wipe it with your finger or a lint free paper towel.
