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!

Operation
Main power switch
only for the DA 362-110
Joystick
Press the main power switch to "l" to use the fan and lighting. If the appliance is not going to be used for a long period of time (e.g. while vacationing) it should be turned off ("0") at the main power switch. The next time it is turned on, the hood will operate at the level previously used. The joystick controls the fan power and overhead lighting.
