Тюнинг режимдери
- Chromatic Mode: The default mode, allowing tuning of any note across the 8-octave range.
- Транспозиция режими: Use the 'TRANS/TEMPERAMENT' button to cycle through transpose settings (e.g., E-flat, B-flat, F). This is particularly useful for transposing wind instruments.

Чайырды тууралоо
- Reference Pitch (Calibration): Use the 'CALIB' buttons (left/right arrows) to adjust the reference pitch (A4) from 410 Hz to 480 Hz in 1 Hz steps. The default is 440 Hz.
- Так жөндөө: The dual display shows the detected note and the deviation in cents. Adjust your instrument until the needle is centered and the LCD shows '0' cents deviation.
Sound Back Mode
This feature helps develop intonation skills. When activated, the tuner plays a reference pitch for the note closest to the input pitch from your instrument. The meter then visually indicates how sharp or flat your played note is compared to the correct pitch. This mode requires the Korg CM-100L Clip-On Contact Microphone (sold separately) for optimal performance, as the built-in microphone might pick up the tuner's own reference sound.
Сезимталдыкты көзөмөлдөө
The large rotary dial on the front panel allows adjustment of the tuner's response sensitivity: 'FAST', 'MEDIUM', 'SLOW', and 'MANUAL'. This helps in accurately detecting pitches from instruments with different attack and decay characteristics.
Техникалык тейлөө
- Тазалоо: Агрегатты жумшак, кургак чүпүрөк менен сүртүңүз. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
