(Figures 6, 7).

Explorer, Proteus and Apollo Canister and Lid
Take the time to inspect the O-ring on the
canister lid before every dive. The O-ring
should be free of grit or dirt and should not
have any signs of damage. Remove the O-ring
from the lid and wipe it down with a clean
cloth before every dive. The lid O-ring does
not require any lubrication. The O-ring groove
on the lid should also be cleaned of any dirt or debris.
Be careful not to damage the sealing surface on the lid or canister.
During transport, the lid should always be attached to the canister to
prevent accidentally nicking either surface. However, you should store
your light for extended periods of time with the lid off or the battery
removed from the canister. Over time, and especially after discharge, the
rechargeable batteries will off-gas potentially combustible gasses. While
off-gassing has not proven itself to be a common problem, you should be
aware of the potential risk by not allowing the canister to sit over time
with discharged batteries sealed inside.
Light Canister
The light canister must keep the battery dry and protected while you are
diving at depth. Halcyon lights use two locking latches to secure the lid
to the canister. When opening or closing your light, work both latches
simultaneously to avoid stressing any side of the lid unevenly.
The canister is configured for attaching to the diver's waist belt. The
unique three-fold webbing attachment on your Halcyon Light is held in
place by two stainless steel bands. The three-piece fold holds the light
with more stability than conventional methods, and prevents the light
from accidentally releasing from the diver's hip. The steel bands can be
raised or lowered on the canister to balance the light on your hip; the
canister should rest parallel to your body when mounted on your harness.

The one-piece design ensures a structural integrity not found in any
other available dive light. Delrin shares the same characteristics of
industrial metals such as aluminum and stainless steel. Some comparable
