I got my EX 10 today...and like many others was a bit confused trying to operate the UI. After a while I did what any good flashaholic does: take it apart ! Now I understand the design, and what to do to easily operate the UI.
This is the Button tube, and the head assy. The tube holds the battery and the whole tube moves when you push on the button!
The tension comes from 3 sources: First the most tension is from the spring in the bottom of the battery tube. Next, the o ring around the tube, and last, the brass ring around the head compresses to make contact with the internal electronics. See next pic!
Note the brass ring. This must be compressed fully to operate the UI . When you press the button, you are compressing this ring. It is important that the ring be pushed fulled down. What this means is that it's more important to press firmly on the button, than quickly. It is especially so, when trying to make the jump to high or low mode after the light is on.
Here is a close up of the tube engaging the brass ring.
Now a photo showing the brass ring depressed.
To reduce the tension...take the tube out and clean it. Use gun oil or something very light to relube the o ring and body. This is just so you can practice with the UI with less tension.
The battery also can cause more tension if it is longer than a primary 123.
OK_ put it together.
Ramping. Turn the light on. After a few seconds-just press and hold the button...no double pushes ! Just push and hold when on. Now the ramping switches from up to down every other cycle.....so, If the light is on full-and doesn't ramp...It might be trying to ramp up...so- do a quick release and push hold.
Once you get to a middle level, let go. Now the level is saved. From the middle, you can practice going up and down...just push-hold after the light is on.
Jumping to Full power or min power. THis is where you need to understand the brass ring operation! You do not need to push real fast! It's more important to push firmly all the way in!
Minimum- With the light on anywhere but min...push and release twice! DO it quickly, but not at super speed! It's important to make the brass ring compress fully. Too slow or too fast will not work...
Max power. With the light on anywhere but max, push the button twice and hold the second push in. THe light doesn't go max until after the double push...and a 1/2 second hold. THis requires a bit more practice, as it is easy to not keep the pressure on the button after you do the double push!
All of these instructions are for when the head is tightened down fully, and NOT in the momentary mode ( head loose).
You can also take the o ring off to get a little bit more tension reduction for practice. Most of the tension is from the battery spring in the tube.
This sounds more difficult than it is, but reducing the tension really helps make it easier to practice. Good Luck!!
