Installing the battery

Make sure to turn the power off before you install or replace the battery.
When it is time to replace the battery, the battery indicator (
The Sledgehammer will continue to function for a while longer, but tuning
will become less accurate. Replace the battery as soon as possible.
1. While lightly pressing the part marked A, pull the battery holder in
the direction of the arrow to slide it out.
2. Making sure to observe the correct polarity, insert the battery so that
the "+" side of the battery is visible.
3. Return the battery holder to its original position.
The backlight will illuminate brightly when sound is input or when a
button is pressed. When there has been no user input for approximately
three seconds, the backlight will dim slightly in order to prevent the bat-
tery from being depleted.
Tuning procedure
1. Turn the left shuttle switch upward. Each time you turn the shuttle
switch, the Sledgehammer will be turned on or off.
If the power is left on for approximately 3 minutes without any user
input, it will turn off automatically.
2. If necessary, change the tuner mode, calibration (reference pitch) and
flat/capo settings.
The procedure with the tuner mode set to chromatic (factory default;
no mode indicator) is described below.
3. Play a single note on your instrument.
The display will show the name of the note that's closest to the pitch
detected. Tune your instrument to the correct pitch so that the desired
note name appears on the display.
4. Once again play a single note on your instrument, and adjust the tun-
ing so that the center segment of the meter (indicated by
In tune.
The pitch is flat.
Even if the pitch is within the range of detection, it may not be possible to detect
the pitch of an instrumental sound that contains large numbers of overtones
or a sound that has a rapid decay.
The meter may respond to vibrations it picks up from the environment; however,
this will not affect tuning of the instrument.
Setting the tuner mode (*M)
Each time you turn the left shuttle switch downward, the
tuner mode changes, with the current mode shown by the
mode indicator.

In addition, in the guitar and bass modes, the string number closest
to the detected pitch appears to the left of the note name indicator.

(LB stands for low B, and HC stands for high C.)
Calibration (reference pitch) settings (*M)
Each time you turn the right shuttle switch upward, the calibration value
(reference pitch) increases in 1 Hz steps. The setting range is between 436
and 445 Hz.
440 → 441 → 442 ... 445 → 436 → 437 ... 440 → 441...
Keep the right shuttle switch turned upward for at least one second to
reset the calibration to 440 Hz.
Specifying flat/capo settings (*M)
Each time you keep the right shuttle switch turned downward, the setting
changes between flat and capo, with the current setting shown by the
FLAT/CAPO indicator.
Flat ( ) → Capo (
To change the flat setting, turn the right shuttle switch
downward while the FLAT indicator is lit up.
The setting range is between 1 and 5 semitones lower.
1 → 2 → 3 → 4 → 5 → 0 → 1...
To change the capo setting, turn the right shuttle switch
downward while the CAPO indicator is lit up.
The setting range is between 1 and 7 semitones higher.
1 → 2 → 3 → 4 → 5 → 6 → 7→ 0 → 1...
When the flat or capo setting is changed 0, the FLAT/CAPO indicator turns off
after a few seconds, and the default setting (no flat or capo tuning) is applied.
Both flat and capo tunings can be set in guitar mode, but only flat tuning can be
set in bass mode, and neither flat nor capo tuning can be set in chromatic mode.
Attaching to the instrument and range of motion
The Sledgehammer tunes by picking up the vibrations of the instrument.
Therefore, be sure to attach the Sledgehammer to the headstock of your
instrument in order to tune it. In addition, the Sledgehammer can be freely
moved so that the display is easy to read.
The Sledgehammer may be damaged if you apply excessive force within its
range of motion, or attempt to move it beyond its intended range of motion.

Please carefully attach the Sledgehammer to your instrument. Leaving the Sledge-
hammer attached for a long time may damage or mark the instrument's surface.
Depending on various factors such as age-related change or the surface finish, there
is a possibility that your instrument may be damaged by attaching this product.
