Warning: Please do not mix batteries of different brands, size, capacity or type. Doing so may
cause damage to the flashlight or the batteries being used.
*18650 Li-ion batteries are powerful cells designed for commercial applications and must be
treated with caution and handled with care. Quality batteries with circuit protection will reduce
the potential for combustion or explosion but cell damage or short circuiting are potential risks
the user assumes.
Battery Replacement
Unscrew the tail cap to take out the battery holder, and then insert four batteries with the
negative terminal towards the spring. After loading the batteries into the holder, insert the
holder with its top spring towards LED assembly; Screw the tail cap on with all of the threads
in proper alignment.
Usage and Maintenance
◎
Please don't disassemble the sealed head
as doing so can cause damage to the flashlight and
will void the warranty.
◎
We recommend the use of high quality batteries. If the flashlight is not to be used for an
extended period, remove the batteries or the flashlight could be damaged by electrolyte leakage
or battery explosion.
◎
Unscrew the tail cap one-half turn or take out the battery to prevent accidental activation
during storage or transport.
The circuit is programmed with a low-voltage protection function. If low voltage is detected, it
will enter into a lower brightness level. If low voltage is detected in the Low brightness level, it
will blink three times a second every 5 minutes. To ensure normal use, TK75 will not turn off
automatically and will work until the batteries run out completely.
◎
When absolutely necessary, the flashlight can be powered by two 18650 rechargeable Li-
ion batteries. Note that runtimes will be shorter and battery life will likely be reduced.
Unscrew the tail cap to take out the battery holder and insert the batteries into the
adjacent
battery compartment of the opposite direction (which can form a battery circuit)
with the negative
terminal toward the spring
. Replace the battery holder and screw the tail cap back on.
◎
When absolutely necessary, the flashlight can be powered by four or eight CR123A
batteries. In this case, the TK75 will run at a low brightness level and the mode switch will be
disabled.
Unscrew the tail cap to take out the battery holder and insert the batteries with the negative
terminal toward the spring (when using four batteries, insert the batteries into the adjacent
battery compartment of the opposite direction to form a battery circuit). Replace the battery holder and
screw the tail cap back on.
◎
The TK75’s runtime can be extended with the addition of body tube segments and battery
holders. Runtime will double with each segment-holder addition but brightness levels will not
be altered.
◎
The flashlight suitcase accommodates optional 4 ARB-L2 18650 rechargeable Li-ion
batteries and an ARE-C1 charging kit (including a battery charger, a DC vehicle connecting
cable along with an AC power cable).
