I haven’t used my steripen in a few years.

I just changed the batteries and attempted to activate my steripen.
The green light turns on when the button is pressed however, the instant I immerge the steripen in my water bottle the green light turn off and nothing happens…

I have an old Steripen Adventurer. I replaced the two CR123A batteries. Is the flashlite supposed to also work? Do I insert the Steripen into the water when the green light stops flashing and the red light comes on?
