Key Features:
- Back-lit Display: Shows note and discrepancy clearly and brightly, even in low-light conditions.

- Auto Power Off: Automatically conserves battery life when not in use.
5. Setup
5.1 Battery Installation
- Locate the battery compartment on the back of the tuner.
- Open the battery compartment cover.
- Insert one CR2 battery, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
5.2 Attaching the Tuner
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 viewing angle.
6. Operating Instructions
6.1 Powering On/Off
- 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 Tuning Your Instrument
- 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 Interpreting the Display
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 flat. Tighten the string.
- If the indicator is to the right of center, the note is sharp. Loosen the string.
- When the indicator is precisely in the center, the note is in tune.
7. Maintenance
7.1 Cleaning
Wipe the tuner with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the display or casing.
