I just updated from fw 3.6 to 5.1.6. Boy, the receiver unit came out having a different radio channel (it worked fine before) so it could not communicate (ex post analysis).
Took me some while to understand that LEDs 1 und 2 combined display the selected radio channel per unit. And more time to understand what to press how long and in which sequence to make it work again.
Acon know a lot of intersting detail about how flash technology works with Pentax. But the user interfacing with those 2 buttons and five LEDs is really secret science.
Now I'll leave the thing as it is: never touch a running system..
