High Temperature Indication
Your light can produce an excess amount of heat on the higher brightness level(s). If
you hold on to your light with a bare hand during operation, your body will conduct
away any excess heat and prevent your light from getting too hot. However, if you
place your light on a table or hold it with a gloved hand, the excess heat is not easily
conducted away. Before your light becomes dangerously hot, a thermal sensor detects
the increasing temperature and reduces the output one brightness level at a time until
the temperature stabilizes at a safe temperature. Your light's temperature is regulated
so you can always pick it up safely and to prevent damage to the LED.
Your light remembers the restricted brightness level and will not allow you to use a
higher brightness level as long as your light remains on. Turning your light off and
back on resets the restricted brightness level and allows you access to all brightness
levels if your light is cool enough to allow them.
Cleaning and Maintenance
Periodically clean the threads and O-ring with a clean lint-free cloth and apply a thin
coat of non-conductive silicon or petroleum grease to threads and O-ring. If the O-rings
become worn or damaged, they should be replaced.
The exposed electrical contacts can be cleaned using a cotton swab moistened with
isopropyl alcohol. Recessed contacts should be cleaned in a counter-clockwise
direction while springs should be cleaned in a clockwise direction to prevent snagging
the swab. Be sure to remove any cotton fibers that may be left behind.
The exterior can be cleaned with a mild soap and water. Rinse well and dry with a lint-
free cotton cloth. Paper towels or tissues should be avoided when cleaning plastic
lenses as scratching will result.
The battery compartment O-ring is: 1.5mm x 21.5mm, 70 durometer Nitrile (Buna-N).
Warnings
Warning: LEDs on the higher brightness levels are very bright. Looking directly into
the LEDs must be avoided. Your light can be intense enough to injure your eyes.
Warning: Never mix battery types or brands and never mix fresh batteries with used
batteries. Doing so may cause a battery to overheat, outgas, catch fire or explode.
Warning: Whereas a sudden total failure is unlikely, it is still possible. Therefore, we
recommend you always carry a second light during critical situations (e.g., caving). We
also recommend you carry enough spare batteries to cover your lighting requirements
plus a reasonable safety margin. It is not necessary to start each trip with new batteries
in your light as long as you have spare batteries along.
Warning: Not all lithium-ion battery over-discharge circuits are compatible with your
flashlight and can cause sudden darkness when the circuit activates. Only use
