Insert photo or drawing
of light here calling out major parts which can be referred to as the
owner reads how to use the light.

To change the battery:

Loosen battery compartment
by turning counter-clockwise while holding head with other hand. Remove
battery compartment. Remove dead battery by tipping battery compartment
so that battery slides out.

Install new battery with
positive (+) contact facing towards front of flashlight.

Screw battery compartment
onto head. Tighten until LED lights up and then loosen until it just
turns off. The Arc6 is now ready to be used.

Note:

If the flashlight is to
be stored for an extended period of time, remove the battery from the
flashlight and store the battery in a cool dry place.

If the battery is inserted
in reverse, the light will not function. Remove and insert the battery
correctly with the positive (+) contact facing towards the front of
the flashlight (LED end).

Turning the light on at the low brightness level:

This flashlight has two
(2) easy to access brightness levels. These can be accessed by either
pressing the tail button or tightening the battery compartment. The
tail button has 2 levels of pressure activation.

Note: the low brightness
level is useful for close-up work, protecting your night vision, etc.

Momentary use

Press the tail button approximately half way to full.
This will activate the low brightness level. The light will stay on
only for as long as the button is held. Releasing the button after such
a continuous press will shut the light off.

Turning the light on at the high brightness level:

Note: the high brightness
level is useful for seeing things at a distance or lighting a larger
area. This level is activated in a similar way to the low brightness
level except that the button is pressed to full.

Press the tail button all
the way to full. This will activate the high brightness level. The light
will stay on only for as long as the button is held. Releasing the button
after such a continuous press will shut the light off.

Constant use

Both methods above describe
how to activate the high and low brightness levels for momentarily or
short durations of usage. The Arc6 can also be turned on at either level
for extended use.

For constant use, the light
can be turned on and left on by twisting the battery compartment clockwise.
As the compartment is tightened, first the low level and then the high
level of brightness will be activated.

Low battery warning:

When the battery is almost
depleted, the LED will automatically dim in steps. The speed at which
it steps depends on how depleted the battery is. At times, it may appear
to step down so rapidly as to flash.

You may continue to use
the flashlight with a partially dead battery at a lower brightness if
needed for emergency reasons. However, we recommend you replace the
battery to restore brightness.

If the light is turned
off and then back on without replacing the depleted battery, the light
will attempt to come on at a lower level.  When the cell is extremely
depleted, the Arc6 will cease to produce light. Please exchange the
battery with a fresh battery.

The Arc6 uses a single
CR123 size lithium battery.

High Temperature Warning:

The Arc6 is designed to
produce more light output than other flashlights in it size. However,
this makes temperature management more important since higher power
levels means more heat is generated. Under certain conditions and if
left unchecked, this could produce enough heat to cause burns to the
hand.

Therefore, the Arc6 includes
a temperature sensor that monitors the housing temperature. In the event
that the housing does begin to approach the temperature safety limit
the high temperature warning will indicate by automatically dimming
the LED power until the temperature begins to drop. Once the light has
cooled off, full power will again become available (if the battery permits).

The temperature limit engages
at about 125-135F as measured on the outside of the head. Again, this
is done to protect the users skin. Modern electronics are good to about
185F (85C) and modern LEDs are good to over 300 degrees (K2 is rated
at a max of 150C, which is 302F). Therefore, the limit which is designed
to protect skin also keeps the electronics and LED well below their
limits.

The difference between
the LED dimming automatically because of a low battery and because of
a hot LED is that with a hot LED, the flashlight will be quite warm.

The temperature fallback
drops to level 3 from any level above level 3 while the battery fallback
drops to the next lower level. Therefore, the temperature fallback is
sometimes a much larger drop.

It is normal for the Arc6 to get quite warm during operation.
This is normal. It should not get hot enough however to cause a burn
or to damage its components. If you help the flashlight stay cool, it
can run at full power for a longer period of time. For example, at level
6, if the Arc6 is left on an insulated surface, it may throttle back
after 2 minutes. But if held in a human hand, it may run for 10 minutes
before reaching temperature limit. This example assumes a fresh battery,
room temperature, etc.

Using Rechargeable Lithium Ion Cells and how the low battery warning
works

This section is mostly
about rechargeables but the low battery function also applies to non-rechargeables.

Rechargeable Lithium Ion
cells are recommended for users who use their Arc6 frequently. This
practice should save money with frequent use when compared to using
non-rechargeable cells. Please note that rechargeable batteries do require
special attention to maximize their cycle life. Consult the instructions
that come with your rechargeable battery system for the correct care
and use of your rechargeable battery.

The Arc6 is designed to
be used with either non-rechargeable lithium ion cells or rechargeable
lithium ion/lithium polymer cells. Rechargeable lithium ion cells can
have a higher voltage (3.3-4.2volts) and require a safety cut-off (usually
2.5v) to prevent over discharging the cells.

Most rechargeable cells
(Battery Station brand for example) have a built in breaker than interrupts
power when the cell voltage is near 2.5v. A potential problem while using protected cells is that the light
may suddenly go dark without warning. Please be aware of this
when using protected cells in mission critical circumstances. Usually,
in the event the battery breaker trips, you can turn the light switch
off, the breaker will reset and then you can turn the light back on
at a lower level. Be warned though that the light will go out suddenly
again and you should change cells immediately.

We recommend un-protected
cells (Powerizer or MP brands for example) in the Arc6 for the best
performance. These cells will not only deliver more current but provide
more of a warning when they are depleted. By unprotected we mean no
over discharge or over current protection. All cells sho
