Compared with the UI of former JETBeam products, I.B.S. is superior in easier operation and better use. There are three memory modes in I.B.S. circuit, each mode can be set by users for different brightness levels or functions. The brightness setting as well as strobe frequency of I.B.S. are infinitely variable, with no traditional preset limits at all. The I.B.S. UI is very simple and straight, users will be able to adjust the brightness / function of the light within shortest time. Compared with those used in former JETBeam products during the past few years, this new driver circuit has greater capability and higher efficiency, but also lower low output. Moreover, this new driver circuit will be the most reliable and stable circuit in the history of JETBeam products, after a long time's testing, we found that the natural damage rate is much lower than that of the previous circuits,and this result strengthens the reliability of JETBeam flashlight.

There are three modes in JET-II PRO ---A B and C. Under default. A is High brightness. B is Low brightness, and C the warning signal. When switched on each time. The light enters mode A. Lightly press the tail cap button, the light will go from mode A-> B-> C in cycle.

Entering the Hidden Menu

Aside of the three default modes, JET-II PRO. can be adjusted to kinds of brightness and functions according to different requirements of users. Lightly press onto the tail cap button three times or more continuously within a second on any mode of A B or C, the light enters Hidden Menu, users can set any levels of brightness or functions preferred for the certain mode.(e.g. Users lightly press the tail cap button three times continuously when on A, then the light enters Hidden Menu, and users can set a brightness level or function for this mode; Likewise, if users enter from B, then you can set another brightness level or function for mode B; etc) There are also three items included in this Hidden Menu---Brightness Setting, Special Functions Selecting and Reset Function.

After entering the Hidden Menu, the light goes into the Brightness Setting directly. Under this item, the brightness will go from Min to Max gradually, and stops at Max, then go back to Min and repeat the process, one cycle takes about 8 seconds. During this process, the light flickers once at Min, and twice at 50% output; and three times at Max(100%) to remind users the current brightness level. Users can switch off the light at any level you preferred, wait for more than 2 seconds to switch on ,then the brightness you choose will be meomorized as the mode from which you enter the Hidden Menu. Users can set different brightness levels for all the three modes according to own habits. NOTE: We have to remind users that even this light can perform at Max(100% brightness level),which is amazingly bright and generates a lot of heat as well when using 3.7V Li-ion battery at high. Users should pay attention to the heat from the light when using it at high brightness level and shall not leave the light on without attendance, in order to avoid causing fire or other accidents! Children are not allowed to use this light independently ,which might cause scald.

After entering the Brightness Setting item of the Hidden Menu, lightly press the tail cap button once, the light enters the Special Functions Selecting. Under this item, the light will show all the special functions automatically. It firstly goes from 1HZ strobe to 15HZ strobe, which takes about 8 seconds. Then it goes on showing other special functions, including warning signal, standby signal (it flickers once every 8 seconds to remind the position of the light), 100% SOS and 5%SOS. If users would like to select any of the special function for the certain mode, only switch off the light under that function, and wait for more than 2 seconds to switch on, then the function will be momerized as the certain mode. Combined with the Brightness Setting, users not only have various brightness choice, but also special functions for different usage according to own habits.

After entering the Special Functions Selecting item of the Hidden Menu, lightly press the tail cap button once, the light enters Reset Function. Users switch off the light, and wait for more than 2 seconds to switch on, it resumes the default modes of A B C from factory (A: High brightness; B: Low brightness; C: Warning Signal). If users do not need to reset, then lightly press the tail cap button once again, the light will go back to Brightness Setting item of the Hidden Menu.
