Controlling the Volume
Your Equity 386 has a speaker which enables it to beep when you
perform certain operations. You can control the speaker’s loudness
with the 
VOLUME 
knob on the front panel, shown below. Turn it to
the right to make the sound louder or to the left to make it quieter.

Resetting the Computer
You can reset the Equity 386 to load a different operating system or to
reload the current operating system. For example, if an error occurs
and the computer does not respond to your keyboard commands,
you can reset the computer and try again. However, resetting erases
all data in the computer’s temporary memory (RAM) that you have
not stored, so reset your computer only when necessary.
You can stop the operation of an MS-DOS command and some
application programs by holding down 
Ctrl 
and pressing either C or
Break. 
Both key combinations send the ASCII code 03-which is
known as the Break signal-to the computer. These methods are less
severe than resetting and may not erase the data in RAM; so try one
of these Break commands before you reset the computer.
