I work on electronic designs and a few years ago we decided to switch out and not use RED LEDs because consumers think that red is a bad thing.
So I get that. The usual blink you asked about should be fine. It's telling you it is busy.
my Olympus C-8080 8MP Digital Camera has a red light that Flashes on the back of the case after i take a picture.The picture comes out ok. My son just gave me this. What is wrong? I don't like it , TOO many buttons. ha ha ha my other one i just push the button to take a picture.
