What I don't dig is the "user defined" mode. Can someone clarify this for me? May be my English is not that good.
The websit says "User-defined mode allows for customized brightness levels and a multitude of functions" but I found the manual online and this is quoted from the manual:
"Slightly loosening the flashlight head, the PA10
access User-defined mode. In this mode, lightly
press the switch rapidly to choose brightness
and functions from "Mid-Low-Lower low-Strobe-
SOS" circularly. Press the switch all the way down
when reach to a desired mode. User-defined
mode has memory function. It will memorize
the brightness/Strobe automatically each time
when you turn off the light."
How is that "user defined"? And I guess "customized brightness level" is customized by Jetbeam, not you. Forget about the multitude of functions for now.
