Setup
1. Battery Installation

- Open the compartment cover.
- Insert the 3V2032 battery with the positive (+) side facing up.
- Close the battery compartment cover securely.
2. Attaching the Tuner to Your Instrument
The clip-on design allows for easy attachment to the headstock of most stringed instruments.
- Gently open the clip.
- Attach the tuner securely to the headstock of your instrument. Ensure the clip has a firm grip without damaging the instrument's finish.
- Adjust the display angle for optimal viewing. The tuner features multi-angle positioning for convenience.

Operating Instructions
1. Powering On/Off
- To power on, press and hold the power button (usually located on the front or side) for a few seconds.
- To power off, press and hold the power button again until the display turns off. The tuner will also automatically power off after a period of inactivity to conserve battery life.
2. Selecting Tuning Mode
The CC-1 tuner offers several tuning modes. Press the mode button (often the same as the power button, or a separate 'Mode' button) repeatedly to cycle through the available modes:
- C (Chromatic): For all instruments and notes.
- G (Guitar): Standard guitar tuning.
- B (Bass): Standard bass guitar tuning.
- V (Violin): Standard violin tuning.
- U (Ukulele): Standard ukulele tuning.
Select the mode appropriate for your instrument.
3. Tuning Your Instrument
Once the tuner is attached and the correct mode is selected:
- Pluck a single string on your instrument.
- The tuner display will show the note being played and a meter indicating whether the note is flat, sharp, or in tune.
- Adjust your instrument's tuning peg until the needle on the display is centered at '0' and the backlight turns green.
- Repeat this process for all strings.

4. A4 Calibration
The default A4 calibration is 440 Hz. If you need to adjust this, refer to the tuner's specific button for A4 calibration (often labeled 'A4' or integrated with the mode button). Press this button to cycle through available A4 frequencies if supported. The CC-1 typically operates at a fixed 440 Hz.
Maintenance
1. Battery Replacement
When the display becomes dim or the tuner fails to power on, it's time to replace the 3V2032 Lithium battery. Follow the battery installation steps outlined in the "Setup" section.
2. Cleaning and Storage
- Wipe the tuner with a soft, dry cloth to remove dust or fingerprints. Do not use liquid cleaners or abrasive materials.
- Store the tuner in a cool, dry place away from direct sunlight and extreme temperatures.
- Remove the battery if the tuner will not be used for an extended period to prevent leakage.
Troubleshooting
- Tuner does not power on: Check if the 3V2032 battery is correctly installed with the positive (+) side up. Replace the battery if it is depleted.
- Inaccurate tuning or difficulty detecting notes:
- Ensure the tuner is securely clipped to the instrument's headstock.
- Verify that the correct tuning mode (Guitar, Bass, Ukulele, Violin, or Chromatic) is selected for your instrument.
- In noisy environments, the tuner's vibration sensor may struggle to isolate your instrument's sound. Try tuning in a quieter area.
- Pluck strings firmly and clearly, one at a time.
- Display is dim or flickering: This usually indicates a low battery. Replace the 3V2032 battery.
