tethering to K5

Has anyone used the PK Tethering set up on their K5. I believe I have set everything up correctly, all works anyway, but.... The display light on the camera flickers until the camera is used, stays on normally, then flickers again after a few seconds. Is this normal or should I be worried?

In anticipation, many thanks.

This is known issue but all you need to do is switch the disply off in the menu, item C22.

Thanks Brian, I wasn't sure if the flickering was a pre-doom warning that something wasn't right.

Cheers

Dave
