Installing batteries

Please don’t charge an alkaline battery.

Before you install or replace the batteries on
your WR-01 or WR-TX, be sure to turn off
the power to both the transmitter as well as
the tuner. The batteries that are included are
intended to allow you to check functionality
and may have a short life.

If the batteries for the WR-01 or WR-TX are low
on power, the low battery indicator will appear
on the LCD display of the WR-01. Both units
will continue to work for a while, but tuning
may not be accurate. Please replace the
batteries with new ones as soon as possible.

Installing batteries in the WR-01

1. Gently press down and slide the battery
case cover on the rear panel of the WR-01
to remove it.

2. Properly orient the batteries and insert
them into the unit.

3. Reattach the battery cover on the WR-01.

1. Remove the clip that’s attached to the WR­TX, then gently press down and slide the
battery case cover on the near panel of the
WR-TX to remove it.

2. Properly orient the battery and insert it into
the unit.

3. Reattach the battery cover on the WR-TX.

Attaching and removing the
supplied clip/strap on the WR­TX

Insert the clip or strap into the clip attachment
groove on the WR-TX and slide it in all the way.
Make sure that you insert the clip or strap in
the correct orientation.

6

When you attach the clip do not touch the
connectors on the WR-TX.

Do not pull the clip by grasping the
pinching portion of the clip. Otherwise, the
clip or strap may break.

When you attach the clip or strap, be sure to
slide it in all the way until it is locked, then
make sure that it’s secure.

Attaching the WR-TX to your
musical instrument

The Wi-Tune measures the pitch of a musical
instrument by sensing vibrations from the
instrument. These vibrations are picked up by
the WR-TX, and wirelessly transmitted to the
WR-01. However, depending where the WR-TX
is attached to the instrument, the vibrations
may not be picked up very well. In this case, try
repostioning the WR-TX to pick up these
vibrations better.
The WR-TX can be attached to musical
instruments such as woodwind, brass or strings
instruments. With some musical instruments,
such as a saxophone, you can attach the WR-TX
to a strap or other part that vibrates, rather than
directly to the instrument itself.
Please refer to the attachment position
examples that are shown in the figures to the
right.

When you clip the WR-TX to or remove it
from the musical instrument, handle it
gently. Attaching the WR-TX to the musical
instrument for a long period of time may
leave a trace on the instrument.

Applying excessive force to the WR-TX or
clip may cause damage.

Using the WR-01 stand

Setting the ID after replacing
the WR-TX

The ID setting data is shared by the WR-01 and
WR-TX. This is done to prevent signal scramble
during wireless communication.
An ID was programmed into the WR-01 and
WR-TX supplied in this Wi-Tune package
before they shipped from the factory.
If you are using a different WR-TX (that was
not included in this package), you must set the
ID on that WR-TX.

1. Gently press down and slide the cover on
the right side of the WR-01 to remoce it.

2. Slide the WR-TX into the WR-01 so that the
WR-TX will lock into the WR-01's connector.

You can do this while the power to each
unit is turned on.

When the transmission of the ID data from the
WR-TX to the WR-01 is complete, the ID indica­tor will light up on the LCD.

3. Turn on the power to the WR-TX and WR-01.

You can do this while the power to each
unit is turned on.

When the transmission of the ID data from the
WR-TX to the WR-01 is complete, the ID indica­tor will light up on the LCD.

4. After the ID data is transmitted, remove the
WR-TX from the WR-01.

The ID indicator on the LCD will turn.

If multiple Wi-Tune units are used in the

9

same location, the tuning meter may not
respond to the proper instrument, or an
incorrect note name may be displayed. In
such cases, resetting the ID will restore
communication between the WR-TX and
WR-01.

If there is no input sound for 20 minutes
while the WR-TX is turned on, or if the
WR-TX and WR-01 cannot communicate
with each other for two minutes, the
power will automatically be turned off.

Turning the power on and off

1. Press the [POWER] button on the WR-01
and WR-TX to turn the power on and off.

If there is no input sound for 20 minutes while the
WR-01 is turned on, the power will automatically
be turned off.

10

Backlight

1. Press the [BACK LIGHT] button. The LCD
backlight will turn on.

Pressing the [BACK LIGHT] button will turn the
LCD backlight on and off.

Wireless tuning

Once the power to the WR-TX is turned on and
communication becomes possible, the built-in
microphone of the WR-01 will turn off,
enabling you to use the wireless function. At
this time, the wireless indicator will appear on
the LCD.

Tuning via wireless microphone

You can use the built-in microphone on the
WR-01 by only turning on the power to the
WR-01. At this time, the MIC indicator on the
LCD will turn on.

Once wireless tuning is enabled, the WR-01
will maintain wireless tuning mode even if
it is unable to receive a signal because the

power to the WR-TX is turned off, the
batteries on the WR-TX are exhausted, or
the WR-TX is moved outside the range of
communication. If you want to switch the
WR-01 to microphone tuning mode, turn off
the power to both the WR-01 and WR-TX,
then turn on the power to the WR-01 only.

Meter mode

When you turn on the power to both units, the
Wi-Tune will enter meter mode. In this mode,
you can tune your instrument by looking at the
meter and using the transmitter or the built-in
microphone on the receiver.

1. Press the [CALIB UP] button or the [CALIB
DOWN] button to select the reference pitch.

You can adjust the reference pitch in 1Hz steps
in the range of 410Hz to 480Hz.

2. Play a single note on your musical
instrument to tune.

The WR-01 displays the name of the note closest
to the recognized pitch. Tune your instrument so
that the WR-01 displays the note name that you
are turning to.

3. Play a single note again and tune your
instrument so that the tuning guide
indicator (the center of the meter) will turn
on.

When you are using the WR-01's built-in
microphone for tuning, try to avoid
allowing sounds from sources other than
the instrument to be picked up by the
microphone.

Even within the measurable range, a note
with lots of harmonics or a quick decay may
not be measurable (e.g., especially notes in
the extreme bass or treble range of the
piano).

When the WR-TX is turned off, only built-in
microphone tuning is available on the WR-

01.

To raise a pitch by a pure major 3rd or a
pure minor 3rd, adjust the tuning so that
the meter needle will point to the pure
major or minor 3rd mark respectively. For
example, if you want to raise the note of A
(0 cent) by a pure major 3rd, first tune your
instrument so that the display will indicate

11

the note name C#, then fine-tune the
instrument so that the meter needle will
point the down arrow ▼ (–13.7 cents) on the
left side of the meter. If you want to raise
the note of A (0 cent) by a pure minor 3rd,
tune your instrument so that the display
will indicate note name C, then fine-tune
the instrument so that the meter needle will
point the up arrow ▼ (+15.6 cents) on the
right side of the meter.

Sound-out mode

In this mode, you can tune your instrument by
referring to the oscillator sound at the reference
pitch (output from the speaker of the WR-01).

1. Press the [SOUND] button to engage
sound-out mode.

2. Press the [SOUND UP] or [SOUND DOWN]
button to select the name of the that which
you want to tune to.

You can select a pitch in the range of C4
(261.63Hz) to C5 (523.25Hz).

12

3. Tune your instrument while referring to the
oscillator sound at the reference pitch
output from the receiver.

4.

To exit Sound-out mode, press the [SOUND]
button.
