Tuning procedure
1. Press the TUNER ON/OFF switch to activate the tuner.
The TUNER ON/OFF LED will light. Because STV-1JB has a Muting circuit,
you can only tune silently, meaning you will not hear your audio signal
through an amp etc.
2. If desired, adjust the calibration and/or select the display mode.
STV-1JB comes from the factory with the calibration set to A=440 and
the tuning mode set to Meter (see “Adjusting the calibration” &
“Choosing a display mode”).
3. Play a single note on your instrument and tune it so that the desired
note appears in the note name display.
The note name closest to the entered note appears in the note name
display.
4. Tune your instrument using the tuning LED meter.
The method for indicating whether your instrument is in tune, sharp or flat
depends on which display mode you choose. (see “Choosing a display
mode”)
5. After you finish tuning your instrument, press the TUNER ON/OFF
switch to turn the tuner off.
The TUNER ON/OFF LED turns off. Now your signal will be heard through
your amp.

Adjusting the calibration
STV-1JB comes from the factory with the calibration set to A=440 Hz. If an

approximately two seconds without pressing any buttons.
The new setting will blink in the note name display indicating the calibration
has been set. STV-1JB will automatically return to tuner mode.
