Introduction
This document assumes you are familiar with the Ra Clicky Flashlight User’s
Guide. This document provides detailed information about the internal operation
of your flashlight and how to customize your flashlight to best suit your needs.
Factory Reset
Please feel free to experiment. You can always return to the original factory settings
by following these steps:
•
Reset your flashlight - i.e., remove the battery for 60 seconds and reinstall. Your
flashlight will light dimly for 5 seconds to indicate the reset.
•
Press and hold the button before the dim reset indication turns off. The light
will become brighter for 10 seconds and then turn off. Release the button
when your flashlight turns off.
Enabling Customization
Customization is disabled by default. Follow these steps to enable Customization:
•
Reset your flashlight - i.e., remove the battery for 60 seconds and reinstall. Your
flashlight will light dimly for 5 seconds and turn off to indicate the reset has
completed. You have 10 seconds following the reset to begin the following
step. After 10 seconds, your flashlight will ignore attempts to enable
Customization.
•
Click the button 20 or more times in rapid succession. After the 20
th
time your
flashlight stops turning off with every other click.
•
Immediately press and hold the button until your flashlight turns off. Your
flashlight will display a dim-to-bright sequence to indicate it is enabling
Customization and then turn off. Release the button after your flashlight
turns off. Customization mode is now enabled.
We recommend you disable Customization after you finish customizing your
flashlight. This allows you to hand your flashlight to anyone without fear that
someone will accidentally modify your settings. See the Option Menu item #6.
Internal Brightness levels
Your flashlight includes 23 regular brightness levels. These brightness levels are
visually spaced so that the difference between any two brightness levels will appear
to be a small even change. This visual spacing takes advantage of the logarithmic
nature of your eyes to see a huge dynamic range – from very bright summer scenes to
dim moonlit scenes. Your flashlight can produce a range of brightness levels that
spans over 2000:1. Each brightness level is separated by a ratio of 1.4:1 – enough to
provide a small but noticeable difference between brightness levels.
The amount of power your flashlight consumes is related to the amount of light it
is generating. The more light generated, the more power consumed. By reducing
the light output by a single level at the higher output settings you can dramatically
reduce the power consumption and dramatically increase the runtimes. And
because of how your eyes perceive light levels, you will barely notice the difference
between the two brightness levels.
The maximum brightness level – also referred to as the burst level – trades
efficiency and runtime for maximum light output. The burst level is automatically
limited to 10 seconds per invocation. The burst level automatically drops to the
next lower brightness level after 10 seconds of use. You may return to the burst
level as often as you like for another burst of maximum light.
In addition to the regular brightness levels, there are three light shows: tactical
strobe, emergency strobe and SOS. These three light shows are treated as if they
were additional regular brightness levels.
The following table shows the brightness levels and the corresponding lumen
output. The maximum output of your flashlight will determine which row to use.
The values in the table are calculated and rounded while values used in the
specifications are often truncated. This may result in the numbers in the table
being one digit higher than found in the specifications.
