Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
Great to be able to set channels again, on an old but stoll fine working TV

Installing the Plasma Display on the Stand
2. Insert the stand into the plasma display
Check that the stand and plasma display are facing the proper direction, then insert the plasma display into the stand. This procedure should be done by at least three persons, since the plasma display is heavy and has a high center of gravity. Hold the bottom and the grips on the back of the plasma display and support the top when inserting the plasma display into the stand.
Plasma Display
Hold both sides of the plasma display and lift it up, then place the plasma display onto the stand so that the holes located at the bottom of the display engage with the stand.
