Step One
250 clicks get you to the options menu. Each option is designated by different flashes. Single clicking will advance you through each option. Double clicking will reverse direction and single clicking will advance you through the options. (Think of it as walking down a hallway one step at a time and to turn around you have to take two steps. Once turned around you take single steps again.)
*250 Clicks*
Option 1. Strobe - the light strobes about once per second
*Click*
Option 2. SOS - 3 quick flashes, 3 longer flashes, 3 quick flashes
*Click*
Option 3. Locator Beacon - 1 dim flash every 3 seconds
*Click*
Option 4. Force setting - denoted by one long flash
When you see the long flash you are on option 4. You press and hold the button for 2 seconds. The light will come on steady and turn off when its time to release the button. Now the Force setting is disabled.
Step Two
Now that the force setting is off, the light will remember the last level it was on. So if you were on maximun and turned it off the next time you turn it on again it will come on at the maximum. Put the light on to whichever level you want to change. In your case secondary and then turn it off.
Step Three
Now you have to do 250 clicks and a press (pushing for more than 2 seconds). The light will stay on after the press. Now you single click to cycle through each brightness settings. You will first be increasing the brightness. Each click will increase the brightness by one level. If you want to decrease you double click to reverse direction and then each click will decrease the brightness by one level (walking down hallway analogy) You can set any brightness you want. Once you get to the level you want, you press and hold the button. The light will come on steady and then turn off telling you its time to let go. That brightness is now selected for secondary
Step Four
Now you can set the light to come on at any of the four brightness levels. If you want it to come on to primary, set it on primary and then turn it off. If you want it to come on to maximum, set it on maximum and then turn it off. Once off now you have to repeat Step One all over again to re-enable the force setting.
Step Five
