"TWISTY" INTERFACE AND
OPERATION
The Beta lights have a "twisty" user
interface – the light is controlled by
twisting the head on or off. When the
light it twisted clockwise (righty tighty)
it will turn on. Unscrewing the head a
small amount will turn it off.
MODES AND MEMORY
Your Beta flashlight may have one, two,
or three modes. See product sticker
for clarification. Beta lights have no
mode memory. They will revert to the
lowest setting after being off for
several seconds. A quick off/on cycle
(less than 1 second) changes modes.
LOW BATTERY WARNING
The driver does not have a built in low
battery warning. If the light dims, fails
to activate, or begins to blink, the
battery needs to be replaced/recharged.
Best practice is to replace/recharge the
battery before it is completely empty.
Modern rechargeable batteries will last
longer if you recharge them before they
are fully depleted.
BATTERY INSTALLATION
The battery should be installed with
the (+) terminal facing the head.
NEVER install batteries backwards.
MAINTENANCE
If the threads become dirty or gritty,
clean them with a soft tissue and/or
cotton swab. Reapply lubrication to the
threads and o-ring to maintain smooth
operation and prevent damage. If the
o-ring dries out, it may tear when
replacing batteries.
Spare o-rings are included with the
Beta. You probably won't need them,
but if the main o-ring ever breaks or
tears, you'll have a replacement
on-hand.
BATTERY COMPATIBILITY
The best battery to use is the NiMH
rechargeable provided with your
flashlight. To purchase batteries and
chargers, visit the link below or your
local hardware store.
Do not use li-ion rechargeable
batteries – they will destroy internal
electronics. Alkaline batteries will
power the Beta QRv2, however they
will release corrosive gas during
discharge and eventually destroy the
light.
This is a high performance NiMH rechargeable
AAA battery. It is recommended for your Beta
QR flashlight and every device in your house.
Stop wasting money and make the switch!
