    Most of the time when I turn mine on it will go through all the bands over and over. It will go on for 20 to 30 min. and then it seems to start working.

Are you getting any Self Calibration or Service Required error messages? If not, then this means that the basic electronics are good and that the problem is within the antenna. If your X50 is in warranty then Escort will repair the antenna for free. If not, then there will be a service fee ($80). Yet I can all but guarantee you that after Escort fixes the antenna problem then you will never have this problem again.The service fee also includes fully testing and calibrating your X50, and updating its internal computer firmware code to their latest code. So the end result is that your X50 will perform just like a brand new one.

Escort 8500 X50 Red K & Ka bands going crazy

As other users said the cleaning took care of the issues. So I took their suggestions because nothing to lose. I took it apart. It is very easy. Just remove 3 crews at the bottom. It has one snap-in hook at one of the corners but easy to separate it. Then I removed the metal part (aluminum die-casted, silver color) from the PCB. It is easy to remove, just remove 6 screws (I think it is 6) then pull the thing out. Inside the aluminum die-cast part is dirty. If you clean inside with Q-tip, you can see the nasty stuff comes off. I think what happens is that the nasty dust comes off then stick on the sensing elements, which might have caused false signal. Also I cleaned tiny elements inside the metal piece with Q-tip. Now it seems working normal. Hope it stays normal. Give it a try if your unit does not act normal. Better than spending $$. Good luck!

The problem is a defective micro switch underneath the City button. Contact Escort about setting up a RMA to get your X50 fixed.

How do cops not get detected by the radar?

Radar detectors usually look for a specific type of signal. Most likely, while the cop is driving around he may not have his radar on, so the detector will not be able to isolate and pinpoint the signal that is needed to activate the alarm to notify you.

Program button is stuck and shaking causes settings to change

Yes, you could remove the button and then your settings wouldn't change. Yet this will be difficult to do since the momentary button switch is very tiny and is difficult to desolder. Your best bet is to send your X50 to Escort for repair.
