enhance the resolution to 0.1 cent increments, first release the ENTER key, then press and hold it again while you press either
PITCH UP or PITCH DOWN. The display screen always presents enhanced resolution of 0.5 cents and 0.1 cents by showing
a decimal point and place: "xx.x ¢".
When the tuner is set for enhanced resolution, the PITCH UP/DOWN buttons increment the tuning adjustments of the tuner
in steps of 0.5 cents or 0.1 cents. This permits intonation measurements with an accuracy of 1/1000 semitone.
The resolution of the tuner may be returned to 1 cent resolution by again using the shifted key buttons for PITCH UP/DOWN
(press and hold the ENTER KEY while you press either PITCH UP or PITCH DOWN). The tuner resolution cycles through
a selection sequence of 1 cent, 0.5 cent, 0.1 cent, 1 cent, etc. Note that the tuner requires you to release the ENTER key
between each step of this resolution selection cycle. Then press and hold it again to go to the next step selection.
Other possible uses of the enhanced resolution of 0.5 cent, or 0.1 cent could be for exact measurements of precise partial tone
frequencies during the manufacture of percussive musical instruments (for example - bells, chimes, gongs, etc.), or for
specific scientific research into the timbrel structure of complex sounds and vibrations in the musical and audible frequency
spectrum.
8. ON-STAGE TUNING USING THE SC-5000 DURING A PERFORMANCE
You can measure your intonation during an on-stage performance by connecting a direct input to the external Input of the
tuner. This direct input can be another microphone, a clip-on pick-up, a direct feed from a mixing console, etc. Your
intonation precision and that of other performing partners can be visible to you and your performing ensemble as you observe
the SC-5000 during the performance. This same external Input may be patched through to the output connector and returned
to a mixing console as an extra signal source to the audience reinforcement. The internal microphone is automatically
bypassed whenever the external Input is connected to a signal source.
When using the external Input in the patch through mode to the Output connector, you and/or your performing partners may
want to tune-up your instruments while the audience is present. The Mute button permits you to execute a silent tuning
without disturbing your audience.
The Mute is a toggle function. Press the Mute button once, and the Input to Output patch through signal path connection
is interrupted. Press this same Mute button again, and the patch through connection is restored. The activated state for the
Mute Mode is indicated by the letter "M" on the regular Run Mode screen below the A = XXX indication as shown here:

9. TUNING FOR NON-EQUAL TEMPERAMENTS
Equal temperament divides a musical octave into 12 equal semitones. The distance in pitch between any two neighboring
notes is exactly 100 cents (1200 cents making one musical octave). Since approximately 1850, Equal Temperament has been
commonly accepted as the standard musical tuning temperament - because any and all musical keys sound "equally" the same
and are completely enharmonic. All keys can be "equally" used - thus the name "Equal Temperament".
