Have a VectorLR (aka Vector 970) and it was showing ?L01 CAL - MARKERS on the display, but then would turn off. I replaced the power cable because the detector kept losing power. Since replacing the power cable I have never seen this displayed again. Why did the messsage not come back after I replaced the power cable?
Also, how many oscillator circuits are there in the 970? I was told my Bel that there are more than one. I figured each one was for each radar band. If that is true (someone correct me here, please), then which band does L01 represent?
thanks for the help, love the site!
