3.3 Tuning Your Instrument

Once the tuner is attached and the correct mode is selected:

1. Pluck a single string on your instrument.
2. Observe the tuner's display. The note name will appear, and a visual indicator will show if the note is flat (too low), sharp (too high), or in tune.
3. Adjust the corresponding tuning peg on your instrument until the visual indicator on the tuner's display is centered and shows a stable, in-tune reading. The display will typically change color (e.g., green) when the note is in tune.
4. Repeat for all strings.

3.4 Calibration

The ProTune tuner may offer calibration settings to adjust the reference pitch (A4 frequency). Refer to the detailed product manual for specific instructions on how to adjust calibration, if this feature is available on your model. Typically, calibration buttons (often shaped like triangles or arrows) are used to increase or decrease the A4 reference frequency.

4. Maintenance

4.1 Battery Care

To maximize the lifespan of your USB-C rechargeable battery, avoid completely draining it regularly. Recharge the tuner as needed. The auto power-off feature helps conserve battery when not in use.

4.2 Cleaning

Wipe the tuner with a soft, dry cloth to remove dust or smudges. Avoid using abrasive cleaners or solvents, as these may damage the display or casing.

5. Troubleshooting

• Tuner not turning on: Ensure the battery is charged. Connect to a USB-C power source.
• Inaccurate tuning readings: Ensure the tuner is securely clipped to the instrument's headstock. Verify that the correct tuning mode (Chromatic, Guitar, Bass, Violin, Ukulele) is selected for your instrument. Pluck strings clearly and individually.
• Tuner not holding charge: If the tuner consistently loses charge quickly, ensure it is fully charged. If the issue persists, contact customer support.
• Physical damage to clip: Handle the tuner with care. Avoid excessive force when attaching or removing it from the instrument.
