Introduction
Congratulations on your purchase of the Ra Twisty Flashlight.
We believe you will find your new Ra Twisty Flashlight to be one
of the most versatile flashlights you own. Your flashlight is built
to provide you with years of reliable service when used every day.
Basic Operation
Rotate the battery compartment clockwise to increase the
brightness level. Your flashlight will sequence from Off to Low to
Medium to High.
Caution: do not continue tightening the battery compartment after
the High setting turns on as this may damage the switch
mechanism.
Rotate the battery compartment counter-clockwise to decrease the
brightness level. Your flashlight will sequence from High to
Medium to Low to Off.
Note: clockwise and counter-clockwise rotation are relative to the
head when the flashlight is pointed away from you.
Low Battery Indication
Your light will momentarily turn off and then back on to half of
the previous brightness level when the battery in your flashlight is
unable to supply enough power to run the current brightness level.
This process is repeated when needed as the battery is used up.
After this process starts, your flashlight will double-blink once a
minute to remind you that the battery needs to be changed.
Selecting a brightness level below the current brightness level will
extend the dying battery and turn off the dying battery reminder.
Your flashlight will start blinking once a second when the battery
is no longer capable of powering any of the regular brightness
levels.
Warning: continued use of a rechargeable battery after your
flashlight begins blinking once a second will result in sudden
darkness because your flashlight will eventually turn itself off to
protect the battery.
Installing the Battery
Unscrew the battery compartment from the head and remove the
old battery from the battery compartment. Insert the new battery
into the battery compartment with the positive terminal out.
Align the head and battery compartment, press them together to
overcome the spring pressure and screw the battery compartment
and head back together.
The light comes on dimly for two seconds following a battery
change to indicate it is functioning correctly. If you do not see this
indication when changing batteries, remove the battery for 60
seconds and try again.
Caution: Only install fully charged rechargeable batteries. Using
partially charged batteries may result in the batteries not being
properly recognized as rechargeable. This can lead to the
rechargeable battery being over-discharged and damaged.
Note: your flashlight protects rechargeable batteries from over-
discharge under most conditions. However, we still recommend
you use batteries with built-in over-discharge protection for an
added level of safety.
Cleaning and Maintenance
Periodically clean the flat end of the battery compartment, the
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 O-ring if it becomes worn or damaged. The battery
compartment O-ring is: 1.5mm x 20.5mm, 70 durometer Nitrile
(Buna-N).
The recessed electrical contacts and interior threads 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. Be sure
to remove any particles or fibers that may be left behind. Apply a
