Warnings

Safety precautions

1.Use only reputable 10180 cells of known origin.

2.Use the included charging unit or a reliable battery charger.Never over-charge or over-discharge cells.

3.Remove and recharge cells when the low voltage indicationis given by the GT Nano (3 blinks and repeated step-downs in light level and eventual shutdown of the light).

3.Charging instruction: 1.Remove the lighthead. 2.Remove the cap from the charging unit. 3.Connect the tube (battery included) with the charging unit. 4.Insert the Micro USB charging cable and connect with the power source to start the charging process. 5.The charging indicator is Redwhen charging, Green when charging is completed.

4.The extraordinary energy density that 10180 cells offers also means that hazardous conditions are created when a cell is short-circuited or damaged. Always treat cells with respect and properly dispose of damaged cells.

5.The GT Nano is a high-intensity flashlight. Do not point the GT Nano directly ata person, animal, moving vehicles or flammable materials.

5.When running at higher output levels the head of the GT Nano will quickly heat up. This is normal.

The temperature may exceed 40C in a few minutes, so please take the necessary precautions when handling the GT Nano.

Quick start

1.Unscrew from the neck and insert one 10180 cell into the flashlight.

2.Double check the polarity every time before closing: The battery must point with plus towards the head.

3.Screw the tube back. The GT Nano will flash twice when electrical contact is made. Continue to tighten the tube to a gentle stop. Do not over-tighten.

4.All functions are performed using the single side button. Note that pressing this button continuously for more than 16 seconds enters the Ul configuration settings (indicated by the light blinking). If this is done inadvertently, exit the configuration settings by simply releasing the button briefly then pressing it again continuously for about 4 s until all the resulting blinks stops.

5.The GT Nano comes factory-set to use the RAMPINGUI:From OFF, 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 GT Nano 0FF. Please see below for further details.

6.There is a very small drain on the battery while OFF. This should not be of any concern, but we recommend removing the cells (or partially loosening the tail-cap)if the GT Nano will not be used for several months.

7.By default the button back-light isilluminated while the GT Nano is OFF. When you switch the Lamp ON, the button light gets off. This is normal and is done to easily locate the button in a dark environment. Turning the GT Nano ON, then OFF, in rapid succession, disables the back-light until the next use. This is also normal.

8.If you transport this light in a bag or your coat pocket use at least the electronic lock-out!

Default Ul: Smooth ramping

This feature-rich Ul provides for smooth ramping of the light output between O and 50%, with an easily-accessible 100%

TURBO mode. This reduces heat, while the lamp is still plenty bright.

Turn the GT micro ON: single-click the button, GT Nano turns ON using the previously used light output level

Ramp light level: hold button

Reverse ramp: while ramping in one direction, release button briefly and hold again

Instant TURBO: double-click

Turn the GT Nano OFF: single-click

MOON mode: from OFF: press the button and release as soon as the Lamp turns on

Strobes: double-click for TURBO, and then double-click again

The strobes are deactivated by default.

(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 1.2s itlocks in and the next single- click is OFF.hold at any time to cycle backwards through the strobes.)

Battery status: triple-click (4 blinks,a short pause, then 1 blink would indicate 4.1V average per cell, for example)

Electronic lock-out: four clicks to disable the GT Nano,same to re-enable the lamp

MOMENTARY mode: five clicks (loosen and re-tighten the tail-cap to return to normal operation)

Factory reset: triple-click (battery status mode), then double-click (driver temperature mode), double-click again (firmware version mode), then hold for about 2s. Four blinks confirm a successful reset.

Alternative Ul: Mode - sets

The GT Nano is factory-set to operate using the contemp- orary RAMPING user interface, as described in the previous section. However, the GT Nano can also be operated using a more conventional MODE-SET style user interface.(See next section for detail on how to set Ul options).

Using the MODE-SET UIthe output does not ramp, it steps from one mode to the next using single-clicks.

Turn the GT Nano ON: single-click

Next mode: single-click before the current mode 'locks in'(1.2s)

Previous mode: hold

Last mode [100%]: from OFF: hold

Turn the GT Nano OFF: single-click button, after resting on a mode more than 1.2s (mode locked in)

Strobes: hold

The strobes are deactivated by default.

(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 1.2s it locks in and the next single- click is 0FF.hold at any time to cycle backwards through the

strobes.)

Battery status: from OFF: single-click followed by hold (4 blinks, a short pause, then 1 blink would indicate 4.1V

average per cell, for example)

Electronic lock-out: from OFF: double-click followed by hold, same to re- enable the GT Nano

Factory reset: from OFF, single-click followed by a hold (battery status mode), then double-click (driver temperature

mode), double-click again (firmware version mode),then hold for about 2s.  Four blinks confirm a successful reset.

Advanced operation

By default the firmware is set to suit most users and applications, but several settings are user-configurable. To enter the configuration settings, hold the button for about 16 s (3 s if in the MODE-SET Ul), do not release until a double flash followed by a single blink is seen.The single blink is the prompt for the first setting. Click the button as many times as required for that setting, or leave the setting alone and simply wait for the next double flash, this time followed by two blinks, indicating that we are now at setting #2, etc.

The GT Nano confirms each click with a blink.A hold skips to the next setting. A continuous press exits the setup menu completely. Four blinks indicate that the setup is completed.

The available settings differ, depending if the GT Nano is currently set to the RAMPING UI or the MODE-SET UI. Note that changing setting 1 flips to the other Ul and immediately kicks you into the table for that Ul:
