temporary fix, but, since alkaline batteries can’t take a charge, it will

PROTOSOUND® VOLUME ADJUSTMENT
Your Proto-Sound® system has two types of volume adjustment. A
manual turn knob on the bottom of the chassis (See Fig. 6 below) allows
you to control all the sounds in the system and a remote control “RESET"
option (Option # 6), allows you to control the volume level of the engine
sounds remotely from the transformer. Turning the volume adjustment
knob clockwise will increase the volume and counterclockwise will lower
the volume of all sounds; bell, whistle, engine sounds, enhanced neutral
sounds, etc. For information on operating the RESET volume adjustment
option, see the section entitled “Programming Proto-Sound® RESET
Options” on the following pages.
