Roger pen won't turn off

Just wondering if anyone knows why the blue light continues blinking blue after the pen is turned off. I need to reset it to make the blue light disappear, but am quite sure that it’s not the proper way. Any idea?

Try an update with Roger upgrader.

If i remember my Pen 1.1, even if it is turned off it would “come on” for a phone call. Try disconnecting on your phone or whatever device it is connecting to.
