Used a small screwdriver and carefully turn is, giving force at one hole first, not too uch, then switch holes.
again, with a little more force in the two holes, upped the force until it came loose, no scratches!
I’m glad I spotted this thread as I received my S70 today and was disappointed to find the voltage indicator had been ditched in this batch. Now I know the circuitry is at least still there and maybe fixable with a replacement opaque cap, well, at least I hope so as it’s pretty much impossible to see through the grey rubber even on low mode.
I, too, was disappointed by the gray switch cover.
I could not distinguish any light at all coming from the battery level indicator under the switch cover, even with the S70 turned on in the low mode and in a totally dark room.
I sent a PM to Thorfire asking whether they can send us replacement covers. No response yet.
