Auto mode

: When a note is played, the tuner automatically identifies

it, and indicates the note closest to it.  It also indicates the
discrepancy between the input note and the note shown
on the display by the position of the LED lamp that lights
up and the cent indication on the display.

Manual mode

: Set the note you wish to tune, and then, play a note.  The

tuner indicates the discrepancy between the input note
and the note you have set by the position of the LED lamp
that lights up and the cent indication on the display.  If the
discrepancy between the notes is more than 50 cents, the
display shows “Hi” or “Lo”.

Sound mode

: The tuner gives out the note you have set.  Tune the

instrument on the basis of the reference note.

(4) Play a note to tune the instrument.

When the Auto mode is selected:

Play a note on the instrument.  Check the note name indicated on the display,
and tune the instrument until the green LED lamp at the center of the tuning
guide 

 lights up.  The discrepancy between the note played on the

instrument and the one displayed on the display is indicated numerically in
cents (cent: a unit corresponding to 1/100 of a semitone).

Range of discrepancy when the green LED lights up : 3 cents or less

When the Manual mode is selected:

1. Press the Note button 

 to set the note you wish to tune.

Settable range: C ~ B (12 notes)

2. Play a note on the instrument.  Tune the instrument until the green LED

lamp at the center of the tuning guide 

 lights up.  The discrepancy

between the input note and the note you have set is indicated numerically
in cents (cent: a unit corresponding to 1/100 of a semitone) on the display.

Range of discrepancy when the green LED lights up : 3 cents or less

When the Sound mode is selected:

1. Press the Note button 

 to set the note you wish to tune.

Settable range: C4 ~ B4 (12 notes)

2. Press the Volume button 

 as required to adjust volume of the reference

note that the tuner gives out (high, mid or low).

3. Tune the instrument on the basis of the reference note.

How to change the reference pitch (frequency of A4):

1. Press the Pitch button 

.  The pitch indication 

 starts flashing.

2. With each press of the Pitch button 

, the pitch increases by 1 Hz.  It

advances quickly if the button is kept pressed.

3. After the desired pitch is displayed, leave STMX1 untouched until the digits

stop flashing.  The pitch you have set is automatically registered.

Precautions on tuning

1. STMX1 may pick up noise from the surrounding environment or the hum

noise generated by electric appliances, and shows indications as if a note
is played.  This is not a malfunction, and STMX1 operates properly when
a note is played.

2. When the Mic input method is used, it is recommended that the tuning

procedure be performed in a quiet environment for accurate tuning.  Also,
bring the instrument close to STMX1 to register a note.

3. If you find it difficult to tune the instrument with the Clip input method, re-

attach STMX1 in such a position of the instrument that the vibrations are
transmitted to STMX1 more clearly.

HOW TO USE THE METRONOME

BACKLIGHT FUNCTION

By keeping the Clip/Mic button 

 pressed for approximately 3 seconds, the

backlight function is turned on.  As any of the buttons is pressed, the backlight

used, the backlight also lights up when a note is input from the instrument.  To turn
off the backlight function, keep the Clip/Mic button 

 pressed for approximately

3 seconds, or turn off the power.

Note: 

While the backlight function is turned on, the battery energy consumption is increased.

situation where other instruments are played
nearby.

Mic input method

: Tuning is made using the note of the instrument

input through the built-in microphone 

.
