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 batteries are capable of supplying the power.
Low battery behavior can also occur if the battery contacts become dirty. Gently wiping
the battery contacts in a counter-clockwise direction, or the springs in a clockwise
direction with a clean dry cloth is normally sufficient to remove dirt. If in doubt, please
replace your batteries.
Note: if you must extend dying batteries - for whatever reason - you should
immediately select a lower brightness setting. The lower the setting selected the longer
the batteries will last.
Note: if you continue to use your light after it has dropped to the lowest brightness
level - where it blinks continuously - it is assumed you are in an emergency situation.
In an emergency situation, your life is more important than your rechargeable batteries
and your light will sacrifice the batteries to keep the light on.
Note: the length of time your batteries will last depends on how you use your light, the
type and quality of batteries you are using and how cold it is. Due to the LED
tolerances, you will see flashlight to flashlight runtime variations when operated under
the same conditions.
Installing the Battery
Unscrew the battery compartment from the head or the button cap and remove the old
battery from the battery compartment. Insert the new battery into the battery
compartment so the positive terminal is toward the head and the negative terminal is
toward the button cap and reassemble. Please make sure both the head and button cap
are screwed on snugly.
Note: you will know it is time to replace the battery when your light blinks down two
brightness levels. That is, your light momentarily turns off and then turns back on at
half the previous brightness, repeating as needed until your light finds a brightness
level that the dieing battery can handle.
Note: always perform a Battery Detect Reset when changing battery configurations –
i.e., for different battery chemistries or different battery cases. Rechargeable batteries
must be fully charged before installation. Your light will protect rechargeable batteries
from over-discharge.
Note: if you insert the batteries backwards in the battery compartment, your light will
not light. Remove the batteries and insert them correctly. Your light is protected
against reverse battery polarity.
