5. Instellen
5.1 Batterij installatie
- Zoek het batterijvakje aan de achterkant van de tuner.
- Open het batterijklepje.
- Plaats een CR2-batterij en let daarbij op de juiste polariteit (+/-) zoals aangegeven in het batterijcompartiment.
- Sluit het batterijklepje goed.
5.2 De tuner bevestigen
The STX2 tuner uses a vibration sensor to detect pitch. For optimal performance, attach it directly to your instrument:
- Gently open the clip and attach it firmly to the headstock of a guitar or bass, or to a suitable vibrating part of other instruments.
- Ensure the display is visible and can be adjusted for your viewhoek.
6. Gebruiksaanwijzing
6.1 In-/uitschakelen
- To power on, press and hold the power button (usually located on the side or front) for a few seconds until the display illuminates.
- To power off, press and hold the power button again. The tuner will also automatically power off after a period of inactivity to save battery.
6.2 Uw instrument stemmen
- Ensure the tuner is securely clipped to your instrument and powered on.
- Pluck a single string or play a note on your instrument.
- The tuner's display will show the detected note (e.g., E, A, D, G, B, e for guitar) and an indicator of whether the note is sharp, flat, or in tune.
- Adjust your instrument's tuning peg until the display indicates the note is in tune. Typically, a central indicator or green light signifies correct pitch.
- Repeat for all strings/notes you wish to tune.
6.3 Het scherm interpreteren
The STX2 features an LED readout that clearly shows the note name. A graphical meter or series of LEDs will indicate the pitch accuracy:
- If the indicator is to the left of center, the note is vlak. Tighten the string.
- If the indicator is to the right of center, the note is scherp. Loosen the string.
- When the indicator is precisely in the center, the note is in harmonie.
