4. Operating Instructions

4.1 Power On/Off

• Press the ON/OFF button to turn the tuner on.
• Press and hold the ON/OFF button for 2 seconds to turn the tuner off.
• The tuner will automatically power off after 3 minutes of no signal input to conserve battery life.

4.2 Mode Selection

Press the MODE button repeatedly to cycle through the available tuning modes:

• C (Chromatic): Tunes all notes.

• B (Bass): Standard bass tuning (E, A, D, G).
• U (Ukulele): Standard ukulele tuning (G, C, E, A).
• V (Violin): Standard violin tuning (G, D, A, E).

4.3 Tuning Process

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

1. Pluck a single open string on your instrument.
2. Observe the LCD display:
   • The note name will be displayed prominently.
   • A meter will indicate pitch deviation.
   • If the needle points to the left (yellow/red), the note is flat. Tighten the string slightly.
   • If the needle points to the right (red), the note is sharp. Loosen the string slightly.
   • When the needle is in the center (green), the note is in tune.
3. Repeat for all strings until your instrument is fully tuned.

4.4 A4 Frequency Adjustment

The standard A4 reference frequency is 440Hz. You can adjust this setting if needed:

• Press the Up or Down buttons to change the A4 frequency.
• The adjustable range is typically 430Hz to 450Hz.

5. Maintenance

• Keep the tuner clean by wiping it with a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Store the tuner in a dry place, away from extreme temperatures and direct sunlight.
• Remove the battery if the tuner will not be used for an extended period to prevent leakage.
• Replace the CR2032 battery when the display becomes dim or the tuner fails to power on.

6. Troubleshooting

• Tuner does not power on: Check if the battery is inserted correctly with the positive (+) side up. Replace the CR2032 battery if it is depleted.
• Inaccurate tuning: Ensure the tuner is securely clipped to the instrument's headstock or scroll. Make sure the correct tuning mode (Chromatic, Guitar, Bass, Ukulele, Violin) is selected for your instrument. Pluck strings clearly and individually.
• Display is dim: The battery may be low. Replace the CR2032 battery.
• Tuner not picking up sound (when using MIC): Ensure the microphone is not obstructed and the instrument is played loudly enough for the tuner to detect the vibrations. For best results, use the clip-on vibration mode.
