Programming Novatac 120P:
This is one of the most intuitive lights when it comes to programming. The programming this light is very easy. Do you find it difficult to program? Well, here are very simple steps that you could use.

1) First, you need to master following gestures: Single Click, Double Click, Triple Click and Click-Press. This will require some practice. Remember what happens when you do these actions. Single Click = "Primary", Double Click = "Secondary", Triple Click = "Minimum", Click-Press = "Maximum".

2) Now know and note that the Levels "Primary" , "Secondary" etc are in Quotes; same applies to "Minimum" and "Maximum", this does not mean that they have to be that way. i.e. Your "Primary" can be a light level of minimum intensity, medium intensity or you can make it maximum intensity, it's up to you, the way you prefer the way you want it to be programmed. Similarly "Minimum" does not have to be a light with minimum level.

3) Now that you have become a master of various click gestures and know the basics, it's time to try some thing.

4) Turn on the light, do a Click-Click-Press. Remember, Click-Click-Press enters light to a Change in Brightness / Mode Selection. You will need to practice the Click-Click-Press to master this gesture. During practice, you might notice that if you keep holding the button i.e. Click-Click-Press(and hold), the brightness starts increasing (ramps up in steps). If you release the button, the brightness stops increasing. Now without doing any thing else, if you once again do a Click-Click-Press(and hold) (keep holding the button) the brightness starts decreasing (ramps down in steps). At any point of time should you face any trouble, you can simply Reset Novatac 120 P to the Factory Mode (see below).

5) OK, Now you have all the required skills and practice to start some basic programming. In fact, you have already learnt how to change the brightness, but yet not saved that setting. If you want to change brightness of any light level, you first go to that light level and do a Click-Click-Press(and hold) Gesture. You notice that the brightness starts increasing. Once it reaches desired level, simply release the pressed button and turn off the light. Turning off the light this way saves the brightness setting.

6) A Question arises, when do you know that the light is at maximum level or minimum level? The answer is simple, during the Click-Click-Press(and hold) when light reaches its maximum, the light flashes twice, same thing applies when ramping down to a minimum. The table below lists the light levels available and the brightness in Lumens for Novatac EDC 120 P.
Levels 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
Brightness 0.08 0.12 0.17 0.23 0.33 0.47 0.66 0.94 1.3 1.9 2.7 3.8 5.3 7.5 10 15 21 30 42 60 85 120

7) So to sum up, lets increase the brightness of "Primary" from 10 Lumens to 21 Lumens.
    a) Click to turn on the light, the mode is "Primary", this is the level you want to change brightness so,
    b) Click-Click-Press(and hold), it starts to ramp up, release button at second step during ramp up (referring to above table) that's 21 Lumens.
    c) Settings are not saved yet, so Click once to turn off the light and save the settings.
    d) That's it. Click once again to verify, you will notice that your "Primary" is now brighter (at 21 Lumens) than factory set 10 Lumens.

Reset Novatac 120 P to the Factory Mode: Turn On the light by Single Clicking, Loosen the bezel (turn anti clock wise). Now turn the bezel (clock wise) to tighten, as soon as you notice some light, keep the tail cap button pressed. Note this action should be performed within a second after you notice light. Do not release the tail cap button until you see following sequence. Bright(5 sec) - Dim(2 sec) - Bright(3 sec) - Off. Now you can release the tail cap button. the 120 P has been reset to Factory Mode.
