Power source: primary or rechargeable batteries, used to supply the operation of the flashlight.
Driver: the electronic circuit used to operate the flashlight and to support the functioning of LED.
The protection from accidental switching on: the function of the flashlight preventing it from being turned on by pressing the button. For example, when it is being carries in a back-pack and there is a possibility of contact between the switch button and other items. This function enables the prevention of an accidental switch-on, and an unplanned loss of power.
Warning indication: a warning blinking, signalling a low battery voltage or a high temperature of LED. It blinks 3 times every 60 seconds. Important notice: If the user is not reacting to the warning blinks (for example, does not switch the flashlight to a lower mode to save energy or reduce temperature), then when the critical levels are reached (low voltage or high temperature) - the flashlight automatically switches to the Firefly mode. At the same time the user retains control of the flashlight. However, one must understand that when the battery is fully discharged - even in the Firefly mode the user loses control of the flashlight. Full pressing: pressing the button of the flashlight until a characteristic click, which confirms its fixing in this state. The lift of the stem of the switch amounts to 0.12-0.16"/3-4 mm.
Easy pressing: pressing the button of the flashlight without fixing it at that state. The lift of the stem is 0.02-0.06"/0.5-1.5 mm.
Ordinary switch-on: switching the flashlight on by a full pressing of the button.
Tactical switch-on: switching on the flashlight using easy pressing of the button.
The head: the front part of the flashlight, which includes: front steel bezel, glass, reflector, LED, driver and the casing of the head.
The body: middle part of the flashlight, including: the casing of the body (battery section), the clip, and silicone O- rings.
The tailcap: rear part of the flashlight, including: the casing of the rear part of the flashlight, the button and the spring, silicone O- rings and back steel bezel.
Mode Lines: if you unscrew the head of the flashlight from its body, you can see the gold-plated contact ring. When screwing the body of the flashlight into its head, the end of the body may or may not touch the ring. In both these states current reaches the circuit board. This enables the creation of two independent Mode Lines: First Line and Second Line.
First Line: this sequence of modes is available when the contact ring touches the end of the body of the flashlight (there is an electric contact).
Second Line: this sequence of modes is available when the contact ring does not touch the end of the body of the flashlight (no electrical contact).
Automemorization of Modes: the ability of the flashlight to memorize the mode in which it was switched off. At the following switching-on of the flashlight it starts operating at that specific mode. The function of automemorization can be turned on (the flashlight memorizes the last mode) or off - in that case the flashlight does not save the mode in the memory and always switches on in the first mode of the Mode Line. This setup can be turned on or off for each Mode Line separately. If Automemorization of Modes is on, the flashlight stores it in its memory even without the power supply.
Indication of battery voltage: the function of the flashlight showing the voltage of battery at the actual moment for the current mode. The voltage of battery enables the user to indirectly determine the amount of operating time left.
Micromode (Firefly): special mode, based on LED microcurrents. Has a very low brightness compared to regular modes and a long runtime (up to 130 days).
Important notice: the micromode is mostly intended for use in critical situations, since its extremely low energy consumption enables up to 130 days of operation. At the same time its brightness is sufficient for walking, for example. Besides, the goal of micromode power supply is doubled: when the main power circuit is damaged, the micromodes will continue functioning through the reserve circuit.
Constant light: light output, not interrupted by any pauses, sudden increases/decreases in brightness etc.
SOS: international distress signal in radiotelegraph communications (using Morse code). The signal consists of a sequence: three dots - three dashes - three dots.
Beacon: the light beam consists of short bright flashes. One flash every 7 seconds. More economical with longer runtime than SOS mode. Can be used to attract attention in a critical situation.
FULL stabilization: full stabilization of the light output, distinguished by a constant brightness, which does not get reduced due to gradual decrease in the battery voltage.
SEMI stabilization: semi-stabilization of the light output, distinguished by a reduction of the brightness with the reduction in the battery voltage.
STEP stabilization: a stepped stabilization of the light output, distinguished by the lowering of the brightness as the battery voltage is reduced, while the driver still enables to fully stabilize the light output at the lower level.
Manufacturer's default presets: default settings pre-programmed by the manufacturer - the number of modes for both lines of modes, brightness and types of modes etc. The brightness and the type of modes in them are based on which modes are used by the customer to solve most of their tasks.
User's preset: designed to save your setups in an individual profile. For example, so that after using one of manufacturer's preset, you could always return to you individual Custom preset.
