Medium, Low and Lowest.
Mode B: Quick press and release the SideKick switch to cycle the output from Tactical
Strobe, SOS and Light-house
Memory: The output level and status will be stored when you power off the light and
restore at next power on.
Battery Installation
Unscrew the Head assembly against power tube and insert new battery with positive ends
towards LED assembly. Replace bezel and hand tighten. Depress tailcap pushbutton switch to
test.
Note: It would not light if battery is inserted in wrong direction.
Mechanical polarity protection will protect the circuit from wrong battery insertion.
CAUTION: CT-ONE flashlights are high-output lighting devices. Due to possible eye
injury, DO NOT look directly into the reflector when the light is switched on. Safety is
your responsibility, too.
External surface temperature will rise during prolonged operation; this is a normal operating
phenomenon.
Battery Replacement
If there is significant decrease in brightness of light output you should replace the battery.
Unscrew the Head housing and remove the old battery. Insert a new battery as mentioned in
Battery Installation Guide
WARNING: Lithium batteries can explode or cause burns if disassembled, shorted,
recharged, exposed to water, fire, or high temperatures. Do not place loose batteries in a
pocket, purse or other container containing metal objects or store with hazardous or
combustible materials. Store in cool, dry, ventilated area. Follow applicable laws and
regulations for disposal.
Maintenance
Clean and lubricate threads with a clean cloth and apply thin coat of silicon-based lubricant to
rubber O-rings. Note: Do not use petroleum-based lubrication on O-rings. After prolonged
exposure to moisture, the bezel and batteries should be removed, inspected, and dried if
necessary.
WARNING: Lumapower reflector is made with high precision process. Do not touch
or clean the reflecting surface using any cloth which may cause damage to the surface
material affecting the illuminating performance.
Non-use Periods.
If CT-ONE is left unused for long period, the installed battery should be removed from the
unit.
Output & Runtime
Accurately specifying light output (lumens) and runtime is complicated for LED flashlights.
Installed batteries and operating temperature are the main factors affecting the light output
and runtime. Lumapower doesn’t guarantee its products can reach the specification under the
using condition of users.
