Operating Instructions

Powering On/Off

Press and hold the central power button located below the display to turn the tuner on or off. The tuner will automatically power off after a period of inactivity to conserve battery life.

Selecting Tuning Mode

After powering on, briefly press the central power button to cycle through the available tuning modes:

C: Chromatic mode (for all instruments and notes)
G: Guitar mode
B: Bass mode
U: Ukulele mode
V: Violin mode

Select the mode corresponding to your instrument for optimal tuning accuracy.

Tuning Your Instrument

The tuner uses a vibration sensor to detect the pitch of your instrument's strings.

Ensure the tuner is securely clipped to the instrument's headstock.
Pluck a single string on your instrument.
Observe the tuner's display:
- The note name will be displayed.
- The tuning meter will indicate if the note is flat (left of center), sharp (right of center), or in tune (center).
- The display backlight will change from blue to green when the note is precisely in tune.
Adjust the string's tension (tighten for sharp, loosen for flat) until the note name is correct, the meter is centered, and the display turns green.
Repeat this process for all strings until your instrument is fully tuned.

Maintenance

Cleaning

To clean the tuner, use a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the device.

Battery Replacement

Replace the CR2032 battery when the display becomes dim or the tuner fails to power on. Always dispose of used batteries responsibly according to local regulations.

Storage

When not in use for extended periods, remove the battery to prevent leakage and store the tuner in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

Tuner Does Not Power On

Check if the battery is correctly installed with the positive (+) side facing up.
Replace the battery with a new CR2032 battery.

Inaccurate Readings or No Detection

Ensure the tuner is firmly clipped to the instrument's headstock. A loose connection can affect vibration detection.
Verify that the correct tuning mode (Guitar, Bass, Ukulele, Violin, or Chromatic) is selected for your instrument.
Tune in a quiet environment. While the vibration sensor reduces interference, excessive ambient noise can still impact accuracy.
Pluck the string clearly and allow it to resonate.
