E-33 Rectifier Operating Manual
MANUALLY ADJUSTING THE PROTO-SOUND®
VOLUME
Your Proto-Sound® system has two types of volume adjustment. A manual
turn knob on the bottom of the chassis (See Fig. 4 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 one
direction will increase the volume. Turning it the opposite directions will
lower the volume of all sounds: bell, horn, engine sounds, Cab Chatter, etc.
For information on operating the RESET volume adjustment option, see the
section entitled “Programming Proto-Sound® RESET Options” on the
