Why does steam volume reset on MTHTrains BIG BOY?

Why does the whistle sound distorted at low voltages on my MTHTrains Toy?
If the WHISTLE seems distorted at low voltages on your MTHTrains Toy, your battery may be undercharged or dead. Try recharging the battery as explained in the battery sections.
Why can I still hear cab chatter when steam volume is set to zero on MTHTrains Toy?
If you still hear the cab chatter sounds when you set the Steam Volume to O Volume on your MTHTrains Toy, it is because setting the steam volume only controls the sound of the steam engine itself. All other sounds, including Cab Chatter, the whistle, and the bell, will continue to play at the volume level set by the manual volume control knob.
