Set up the Digital Sonifier following the
instructions in this manual. If no horn
is currently installed,
• Mount a 1/2" Disruptor horn (with a
flat tip, if tapped) to the Converter.
After you have connected the Con-
verter/Horn to the Converter Cable,
verified all other connections are as
desired:
• Turn the Unit On, and observe the
self-test displays.
Adjust the Amplitude control to
approximately 50% (observe the
value on the front panel display).
Verify that the Horn is not touching
anything.
• Press the Test button on the front
panel. Observe the front panel display.
If the system showed readings on
the display during the Test,
you may either proceed with your
experiments, or
• Turn the unit off.

To obtain this result
Prepare the Sonifier to operate, if it
was not previously assembled.
Verify that the system passes all its
self-tests, observing that there are
no error messages on the front panel
display.
The Digital Sonifier advances to the
"Ready" mode and shows the normal
Ready display (see page 2-4).
Ensures that ultrasonic energy will
be at some mid-range value, and will
not cause damage if you were using
a microtip (must be less than 70%).
Verifies the ultrasonic output of the
system. You may hear a soft, high-
pitched sound. The bargraph display
will show some output value. The
test will run for 2 seconds, then stop.
Verification that the Digital Sonifier is
operating and is ready to be set up
for your experiment.
