Whilst this is a photo copy, and some of the pages are a little askew, it was all readable and intact. A real bonus finding an old manual for a classic piece of kit that no other site had.
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.

Before using your microwave oven for the first time
Wipe over the front of the appliance with a damp cloth. Do not use abrasive cleaning agents (these can damage the surface). For stainless steel fronts use a suitable stainless steel cleaning agent that leaves a protective film against fingerprints. Before you first use the appliance, remove all the accessories (including the turntable and turntable support) from the cooking area. Wash the accessories in warm water and washing up liquid. Wipe the cooking space with a soft, damp cloth.
Setting the clock
Plug the appliance into the mains. The display starts to flash "00:00". The dots between the digits will flash rapidly. Example: To set 12:15: Set the time of day with the Timer knob. Confirm by pressing either the Start button or the Clear button. The time of the day is displayed. The dots between the digits flash slowly.
The appliance is now ready for use.
The Timer knob can be turned clockwise (to increase) or counterclockwise (to decrease).
The time of day can be changed at any time by pressing the Start button for five seconds, turning the Timer knob and confirming with the Start-or Clear button.
