PG9935 Enrollment and Adjustment

I just got the PG9935 Shock sensor. After looking through the forum I found someone mention enrolling as Door/Window -M in order for shock and reed I assume that is correct? I also attempted to adjust/calibrate my sensitivity because it was set to an 8. I did the test to show a hit on the window and all that. I hit the up button and got the G followed by the number. I adjusted down to 7 and then hit both buttons to get the A and left that at 0 because not really sure what that is. I then hit both buttons together again and a G comes back up with 8. No matter what I do I can’t get it to save my setting of 7 versus 8. Am I doing something wrong? Also what is the A for since the documentation doesnt really say.

Yes, Door/Window-M should be the selected type.

A stands for the “Accumulate” setting. See here for a manual excerpt:

Do you see an E display when making the changes?

You could alternatively edit the sensitivity by using the preset values in the sensor configuration menu on the IQ Panel for that zone.

I get the G which meant it is connected per the document. I do have A set to 0. I ended up editing the sensitivity within the Panel.
