Operating Instructions
Tuning Your Guitar
The WST-550G uses a vibration sensor to detect the pitch of your guitar strings. This ensures accurate tuning even in noisy environments.
- Ensure the tuner is securely clipped to the headstock and powered on.
- Pluck a single string on your guitar. The tuner's display will show the detected note name (e.g., E, A, D, G, B, E for standard guitar tuning).
- Observe the LED indicators:
- If the LED is to the left of the center (e.g., -10, -20), the note is flat. Tighten the string until the LED moves towards the center.
- If the LED is to the right of the center (e.g., +10, +20), the note is sharp. Loosen the string until the LED moves towards the center.
- When the LED is at the center (0) and turns green, the string is in tune.
- Repeat this process for all strings until your guitar is perfectly in tune.

- Gently slide open the battery tray.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing upwards.
- Slide the battery tray back into the compartment until it clicks securely into place.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tuner does not power on. | Battery is depleted or incorrectly installed. | Replace the CR2032 battery or ensure it is installed with the correct polarity (+ side up). |
| Tuner does not detect vibrations or notes. | Tuner is not securely clipped to the headstock; instrument is not vibrating sufficiently; tuner malfunction. | Ensure the tuner is firmly clipped to the headstock. Pluck the string more assertively. If the issue persists after checking the battery and attachment, contact support. |
| Inaccurate tuning readings. | External noise interference; loose tuner clip; faulty unit. | Ensure the tuner is securely attached. The vibration sensor is designed for noisy environments, but extreme noise might still affect it. Try tuning in a quieter area. If the problem continues, consider contacting support. |
