The FT03 comes factory-set to use the RAMPING UI: From OFF, press&hold the side button. The
light output will ramp up from a very low level to full power. Release the button when the required
light level is reached. (The full ramp takes about 3 s. To signal ‘End of Ramp’ it does a subtle
blink ) Use a
single-click at any time to turn the FT03 OFF. Please see below for further details.
There is a very small drain on the battery while OFF. This should not be of any concern, but we
recommend removing the cell (or partially loosening the tail-cap) if the FT03 will not be used for
several months.
If you transport this light in a bag use at least the electronic lock-out! It will burn things on higher
levels!
Default UI: Smooth ramping
This feature-rich UI provides for smooth ramping of the light output between 0 and 50%, with an
easilyaccessible 100% TURBO mode.
Turn the FT03 ON: single-click the button, FT03 turns ON using the previously used light output level
Ramp light level: press&hold button
Reverse ramp: while ramping in one direction, release button briefly and press&hold again
Instant TURBO: double-click
Turn the Lamp OFF: single-click
MOON mode: from OFF: press the button and release as soon as the FT03 turns on
Strobes: double-click for TURBO, and then double-click again
The strobes are deactivated by default. To enable strobes you must klick 3 times in setting #4
(ramping) or setting #8 (modes). (Use single-clicks to cycle forward through the different types of
strobes, but you have to be quick: If resting on a strobe longer than 1.2 s it locks in and the next
single-click is OFF. Press & hold at any time to cycle backwards through the strobes.)
Alternative UI: Mode-sets
The FT03 is factory-set to operate using the contemporary RAMPING user interface, as described in the
previous section. However, the FT03 can also be operated using a more conventional MODE-SET style
user interface. (See next section for detail on how to set UI options). Using the MODE-SET UI the
output does not ramp, it steps from one mode to the next using single-clicks.
Turn the FT03 ON: single-click
Next mode: single-click before the current mode ‘locks in’ (1.2 s)
Previous mode: press & hold
Last mode [100%]: from OFF: press & hold
Turn the Lamp OFF: single-click button, after resting on a mode more than 1.2 s (mode locked
in)
Strobes: press & hold
The strobes are deactivated by default. To enable strobes you must klick 3 times in setting #4
(ramping) or setting #8 (modes). (Use single-clicks to cycle forward through the different types of
strobes, but you have to be quick: If resting on a strobe longer than 1.2 s it locks in and the next
single-click is OFF. Press & hold at any time to cycle backwards through the strobes.)
Battery status: from OFF: single-click followed by press & hold (4 blinks, a short pause, then 1
blink would indicate 4.1 V average per cell, for example)
Electronic lock-out: from OFF: double-click followed by press & hold, same to reenable the FT03
Factory reset: from OFF, single-click followed by a press & hold (battery status mode), then
double-click (driver temperature mode), DoubleClick again (firmware version mode), then press &
hold for about 2 s. Four blinks confirm a successful reset.
Advanced operation
By default the FT03 is set to suit most users and applications, but several settings are user-
configurable. To enter the configuration settings, press&hold the button for about 16 s (3 s if in the
MODE-SET UI), do not release until a double flash followed by a single blink is seen. The single blink is
