הוראות הפעלה

מצבי כוונון

• Chromatic Mode: The default mode, allowing tuning of any note across the 8-octave range.
• מצב טרנספוזיציה: 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.
• Temperament Selection: Press the 'TRANS/TEMPERAMENT' button repeatedly to select from various built-in temperaments for historical tunings.

התאמת המגרש

• 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.
• כוונון עדין: 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.

בקרת רגישות

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.

תַחזוּקָה

• ניקוי: נגבו את היחידה במטלית רכה ויבשה. אין להשתמש בחומרי ניקוי שוחקים או ממסים.
• החלפת סוללה: Replace batteries when the low battery indicator appears on the display. Always use fresh AA batteries.
• אִחסוּן: יש לאחסן את המכשיר במקום קריר ויבש, הרחק מאור שמש ישיר וטמפרטורות קיצוניות.

פתרון בעיות

• אין כוח: ודא שהסוללות מותקנות כהלכה ואינן התרוקנות. החלף אותן במידת הצורך.
• Inaccurate Tuning: Check the selected tuning mode (Chromatic, Transpose, Temperament) and reference pitch (A4 calibration). Adjust the sensitivity dial if the instrument's sound is difficult to detect.
• Sound Back Mode Issues: Verify the CM-100L microphone is securely connected and functioning.
