SETTING THE ENGINE VOLUME
Of all the sounds that come with each ProtoSound-equipped locomotive,
the one most often turned down is that of the engine volume because it is
the one sound normally heard whenever the engine is running and is what
usually can become tiresome to the ear over prolonged running sessions.
The volume adjustment is controlled through RESET Feature 6.
To access the feature, advance the transformer throttle to put the engine in
RESET. Move the throttle up and down, as described on page 5, 6 times.
After you hear the “clank" and “clink" indicating that you are in Feature 6,
press the whistle button
to select the engine
volume level you desire.
Pushing the whistle
button once will give
you full volume, which
is the factory setting.
Pushing the whistle
button a second time
will give you 50% volume, pushing it a third time will give you 25%
volume and pushing it a fourth time will give you no engine sound. The
microprocessor will immediately play the sound level each time the whistle
button is pushed so that you can decide if it is acceptable. You can recycle
through the four choices by simply continuing to press the whistle button.
Once you have decided on the appropriate volume level, turn the
transformer throttle off and on again or press the transformer direction
switch to lock in your selection. The volume adjustment will remain set at
the level you have chosen until you change it again. Regardless of the
engine volume setting, the horn, bell, compressor and Cab Chatter sounds
will function normally. In fact because only the engine volume is affected
by selections in Feature 6, when you select 0 volume, you can still hear the
horn, bell and Cab Chatter sounds when the engine is running or in neutral.
