Remote control problem

[dannybou]

I have obtained a JJC remote control which I am told is compatible with my camera, a Pentax istDL. Problem is I can't get it to work. I've checked the battery inside the remote and it is fine. I enter into the function mode of the camera and set it for remote control. I see the red light blinking on the camera but when I press on the remote control's button, nothing happens. Am I doing something wrong? Am I forgetting to do a step? Thanks
