PROMETHEUS LIGHTS Foursevens QUARK A Series User manual

"CLICKY" INTERFACE AND
OPERATION
QUARK lights have a "clicky" user
interface – the light is controlled by
clicking or pressing the tail cap switch to
turn the light on or o.
A light “press” on the switch activates
the light in momentary mode. A full
“click” latches the light on or o.
MODES AND MEMORY
When the light is on, change modes with
a quick o/on cycle (less than 1 second).
Mode memory is a “hybrid” type that
remembers the last setting, but reverts
to mode 1 of the current configuration
on the next mode change.
USER PROGRAMMING
The QUARK has six user selectable
configurations. Enter the configuration
menu by cycling the light 10 times in
less than 3 seconds. Use a momentary
“press” (not a “click”) when entering
configuration mode. The light blinks a
number of times equal to the configura-
tion number selected. Cycling the
button one time changes to the next
configuration. Leaving the light o for 5
seconds saves the current configuration
to memory.

CONFIGURATIONS
(1) High + Burst
(2) Max / Strobe
(3) Medium / High + Burst
(4) Low / Medium / High + Burst

MODES: QKA (QK2A)
Low (Moonlight) = 1.5 Lumens
Medium = 40 (80) Lumens
High = 150 (300) Lumens
Max = 250 (500) Lumens
Burst = 250 (500) Lumens
SOS = International Distress Signal
Strobe = 250 (500) Lumens @ 20Hz
Beacon = 2 blinks every 5 seconds
BURST MODE (100% OUTPUT)
Typically 100% output is not needed.
Burst mode is a battery saving feature.
If you do need full output, activate burst
mode with two very quick cycles (‹.25
seconds). Burst mode has no memory,
so the light will return to the last saved
mode.
The light maintains Burst Mode for 30
seconds and then ramps down to High
mode over the next 30 seconds to
prevent over heating.
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.
Blinking is caused by the light powering
on/o and may cause the light to
accidentally enter the configuration
menu and change the saved program.
BATTERY INSTALLATION
The battery should be installed with the
(+) terminal facing the head. NEVER
install batteries backwards.
BATTERY COMPATIBILITY
The best battery to use is the NiMH
rechargeable provided with your
flashlight. To purchase batteries and
chargers, please visit the link at the
bottom of the next page.
Alkaline batteries will power QUARK
lights, however they release corrosive
gas during discharge, are prone to
leaking, and will eventually destroy the
light.

QUARK “A” series lights are NOT
compatible with li-ion rechargeable
batteries. Damage caused by alkaline
or li-ion rechargeable batteries is
NOT covered under warranty.
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
QUARK. You probably won't need them,
but if the main o-ring ever breaks or tears,
you'll have a replacement on-hand.
