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.
Sono molto soddisfatto e, quando mi necessiterà, mi avvarrò nuovamente di questo servizio!

Using the headsets
Mono/Stereo selection (HME 100 only)
In general, you�ll receive a mono sound source so that the Mono/Stereo switch can remain set to �Mono�. When using a stereo intercom system, set the headset to stereo operation. Remove the ear cushion (u �Replacing the ear cushions�) from the earcup with the microphone boom attached and set the Mono/Stereo switch to �Stereo�.
Adjusting the volume
Exposure to loud sounds can cause hearing damage! Set the volume control to a medium value. Make sure that you can hear critical sounds such as warning alarms.
