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.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

For best battery performance, you should follow these guidelines: Use your battery for its intended purpose only. Only use Samsung-approved batteries and desktop chargers. These chargers are designed to maximize battery life. Using other batteries or chargers will invalidate your warranty and may cause damage as well. You must never use a battery charger that is damaged in any way or worn out. To avoid damage, only charge the battery in temperatures that range from 32° F to 104° F. Do not use the battery charger in direct sunlight or in high humidity areas (such as a bathroom). When a battery charger is not in use, disconnect it from the power source. Never dispose of the battery by incineration (fire). Keep the metal contacts at the battery base clean. Do not attempt to disassemble or short-circuit the battery, as injuries or burns may result. You may need to recharge the battery if it has not been used for a long period of time. Replace the battery when it no longer provides acceptable performance. It can be charged hundreds of times before it will need to be replaced.
