Meter Adjustment Control (bottom of the unit)
Normal Tuning (AUTO CHROMATIC Mode)
1. Connect the plug of the included piezo mic to the INPUT jack and
mount the piezo mic on the instrument you want to tune.
To carry out tuning using the built-in microphone, connect nothing to the INPUT
jack and place the TU-12BW close to the instrument. If you have a digital wind
controller or an instrument with a built-in mic or pickup, plug its output into the
INPUT jack.
2. Press [POWER] to switch the power on.
3. Press [AUTO/MANUAL] to enable the "AUTO" setting (lighting the
green indicator).
In AUTO CHROMATIC Mode, the TU-12BW automatically displays a note's pitch (the
note name) as you play it on the instrument. Most of the time, AUTO is the most
convenient mode to use.
When you want to practice producing a specific pitch, you may want to
use MANUAL mode; in this mode, only the pitch that you specify is
detected and displayed.
4. Play a single note on the instrument.
While the note is sounding, the name for the note's current pitch is displayed.
The meter and Tuning Guide show how far the note is from the correct pitch.
5. Tune the instrument.
With the intended note name displayed, tune the instrument so that
on the Tuning Guide light simultaneously and the meter's needle points to 0 (the
center position).
When the Accu-Pitch feature is on, the tuner makes a beeping sound when the note
is stabilized at the correct pitch, informing you that the note is in tune.
Training for a Specific Pitch
(Tuning in MANUAL Mode)
1. Connect the plug of the included piezo mic to the INPUT jack and
mount the piezo mic on the instrument you want to tune.
To carry out tuning using the built-in microphone, connect nothing to the INPUT
jack and place the TU-12BW close to the instrument. If you have a digital wind
controller or an instrument with a built-in mic or pickup, plug its output into the
INPUT jack.
2. Press [POWER] to switch the power on.
3. Press [AUTO/MANUAL] to enable the "MANUAL" setting (lighting the
red indicator).
4. Press [ ] or [ ] to display the note name for the specific pitch you
want to practice and/or tune.
5. Play a single note on the instrument.
The meter and Tuning Guide show how far the note is from the correct pitch.
6. Tune the instrument.
With the intended note name displayed, adjust the instrument's tuning so that
both and on the Tuning Guide are lit and the meter's needle points to 0
(center position).
When the Accu-Pitch feature is on, the tuner makes a beeping sound when the note
is stabilized at the correct pitch, informing you that the note is in tune.
TU-12BW Settings
Changing the Reference Pitch for Tuning
1. Hold down [PITCH] and press [ ] or [ ] to choose the reference
pitch you want.
The indicator flashes. Choose the reference pitch you want by getting it to flash.
2. Release [PITCH] to set the selected reference pitch.
This setting is saved in memory when the TU-12BW is powered off.
Tuning While Listening to the Reference Tone (Sound Mode)
1. Choose the tuning mode you want to use (AUTO or MANUAL).
2. Press [ ] (Sound) to play the reference tone.
3. Press [ ] or [ ] to light the indicator for the note name you'd like to
use as a reference.
The sound of the note name shown by the indicator is played.
Pressing [ ] and [ ], you can play reference tones in half-step increments
over five octaves (C2 to C7).
4. Tune the instrument to the reference tone.
When you're using Sound mode, tuning cannot be performed using the
built-in mic (the built-in mic is disabled).
5. Press [ ] (Sound) to stop playing the reference tone.
Changing the Meter Response Speed (Quick Response Feature)
The Quick Response feature increases the speed of the meter's response to the incoming
pitch. You may find this handy for some advanced music practice applications.
1. Press [QUICK RESPONSE] to turn the Quick Response feature on/off.
Quick Response is activated when the red indicator lights.
Indicators
These show the current note's name (C-B),
natural or sharp status (#), the master reference
pitch (438-445), and a warning when the
battery is low.
DC IN jack
Connect the AC adaptor
(optional BOSS PSA series) here.
INPUT jack
Connect devices such as the
included piezo mic or a digital
instrument you want to tune here.
QUICK RESPONSE
This changes the meter
response speed.
(Sound button)
Use this to turn the reference tone's
sound on and off.

These change various settings.
PITCH
This changes the settings for the reference
pitch.
POWER
Switches the power on and off.
Built-in Mic
This allows you to tune an acoustic instrument
when it's not convenient to use the included
piezo mic. For the best results with the built-in
mic, move the TU-12BW as close to the instrument
as possible while tuning.
and
Calibrating the Meter's Needle
Rarely, the meter's needle may drift out of calibration, causing the needle to point
slightly off from the 0 position even when the Tuning Guide's
light simultaneously. This can occur over time as the unit is transported, or if the unit is
handled in a rough fashion. If this occurs, you can recalibrate the needle using the
following procedure.
During normal use, the meter's needle almost never drifts out of
calibration. To adjust it, be sure to use a small Phillips screwdriver (a 2.3
mm precision screwdriver).
1. Hold down [PITCH] and turn the power on.
Confirm whether or not the needle is pointing at the 0 position.
2. If the needle is not pointing to 0, carefully turn the adjustment screw
with a small, precision phillips screwdriver (2.3 mm) until the needle
points to 0.
3. After completing calibration, press [POWER] to switch off the power.
Useful Features
Preventing Battery Drain If You Forget to Switch Off the
Power (Auto Power Off Feature)
When the TU-12BW is turned on and powered by batteries, the power is turned off
automatically if approximately 30 minutes passes without any button being
pressed.
Deactivating the Auto Power Off Feature
You can temporarily deactivate the Auto Power Off feature when you power up the
TU-12BW. To do so, simultaneously hold down [ ] and [ ] while you press
[POWER] to turn on the power.
The Auto Power Off feature is always enabled when you switch on the power in the
usual way.
Using a Tone to Indicate Tuning is Completed
(Accu-Pitch Feature)
When the Accu-Pitch feature is on, a beeping sound is played when the pitch of the
instrument you're tuning stabilizes within a range of three cents above or below
the correct pitch. This sound tells you that the pitch is in tune.
Switching the Accu-Pitch Feature On and Off
1. Hold down [ ] (Sound) and press [POWER] to switch on the power.
If no sound is heard from the unit as it's powered up, it means that the Accu-Pitch
feature has been deactivated. To enable the Accu-Pitch feature, perform the same
operation again; if you hear a beeping sound when the power comes on, it means
that Accu-Pitch has been enabled.
Memory Features
Once batteries are installed in the TU-12BW, the settings described below are
retained in memory even after the power is switched off.
Removing the batteries returns all settings to their factory defaults.

Changing the Batteries
The BATT. indicator flashes when the batteries begin to
run down.
Replace the batteries as soon as possible.
* When turning the unit upside-down, place it on a soft cloth or
the like so as to prevent damage to the panel.
1. Open the battery compartment (located
on the bottom of the unit) by sliding the
cover toward OPEN.
2. Remove the old batteries from the battery compartment.
3. Insert two of the same type of fresh AAA batteries.
* Make sure the "+" and "-" ends of the batteries are oriented correctly.
* Do not mix fresh batteries with used ones, or mix batteries of different types. Doing so can result in
fluid leakage.
4. Slide the cover of the battery compartment back into place.
