How to set a Pop2 v2.39 sammie

Can someone give me a hint on how to change the UI on the v2.39?
Mine is set to UI2 and want it UI5.
I have these instructions but don't know where to begin and end.

To change UI's

1) click 1 + latch
2) click 2 + latch
3) click 1 + latch
4) click 2 + latch
5) click 1 + latch
6) click 2 + latch
7) click 1 -> user set mode => UI change mode (out of 6) + user level setting

latch = wait 1 second.

Here's the UI definitions for the POP2 v2.39

UI-1 = user - high - set - r.strobe
UI-2 = low - user - high - strobe (default)
UI-3 = high - user - r.strobe
UI-4 = low - user - high - strobe - sos - throb
UI-5 = low - user - high - r.strobe - sos - throb - set

Thanks

:help: You're not alone ! I've been struggling with it for a while myself

The instructions say to click (x times) + latch. That means click it that many times and then wait for a second or so and the light will make a little flick. The flick = latch.
I had a little bit of a learning curve, but after doing it a couple of times it got much easier. Now I have my POP2 in a FF II with RCR2 body. As I read through the instructions I click/twist and watch for the latch/flick out of the corner of my eye.

I finally got it down

You just alternate 1 and 2 click/latches 3 times until it goes into UI change mode (rapid flickering) then wait for the number of flashes (representing the UI you want) and turn it off !

Once you get it, it's super easy and impossible to get into it by mistake.

I love it ! I can't wait to get a few more ! I think every flashlight should have one !! Why not with all the options. It's all good with no downside.
