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

Battery Replacement
Push Release Remove
Slide
Carefully remove and replace battery with a highquality alkaline cell. Replace the battery cover and reinstall the module by reversing the removal process, finally snapping into place.
Output Connection
The ¼� jack on all models provides an unbalanced, line-level connection to most any amplification system. Inserting a plug into this jack also turns on the preamp system. Please note that the tuner is functional without connecting a cable to this jack.
