Cleaning And Maintenance; Additional Notices And Cautions - HDS Systems EDC Tactical User Manual

The first method is to enable and use the Button Lockout feature. See
Button Lockout in Customizing Optional Features (section 14) for
details.
The second method is to unscrew the battery compartment from the
head by one half turn. This will leave the O-ring completely covered.
You restore operation of the button by screwing the battery
compartment completely into the head.

7. Cleaning and Maintenance

Periodically clean the open end of the battery compartment, threads
and O-ring with a clean lint-free cloth lightly moistened with isopropyl
alcohol. Apply a coat of non-conductive silicon or petroleum grease to
these surfaces.
Replace the battery compartment O-ring if it becomes worn or
damaged. O-ring: 1.5mm x 20.5mm, 70 durometer Nitrile (Buna-N).
The recessed electrical contacts and interior threads in the head can
be cleaned using a lint-free swab lightly moistened with isopropyl
alcohol. Recessed contacts and threads should be cleaned in a
counter-clockwise direction to prevent snagging the swab in the
threads. Be sure to remove any particles or fibers that may be left
behind. Apply a coat of non-conductive silicon or petroleum grease to
the interior threads and contacts.
The exterior can be cleaned with a mild soap and water. Rinse well
and dry with a soft cotton cloth.
Note: the anti-reflective coating on the lens can be abraded by
excessive rubbing or cleaning. Never use paper tissues or paper
towels to clean or dry the lens as the fibers are abrasive.

8. Additional Notices and Cautions

Notice: your flashlight protects rechargeable batteries from over-
discharge under most conditions when used as directed. IMR lithium-
ion batteries can be used safely without protection circuits – and are
normally supplied without protection circuits. However, ICR lithium-ion
batteries should always have built-in protection circuits for your safety.
Notice: only install fully charged rechargeable batteries. Using a
partially charged battery may result in the battery not being properly
