ઓપરેટિંગ સૂચનાઓ

ટ્યુનિંગ મોડ્સ

• Chromatic Mode: The default mode, allowing tuning of any note across the 8-octave range.
• ટ્રાન્સપોઝ મોડ: 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.

પિચ ગોઠવણ

• 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.
• સરસ તાલમેલ: 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.

સંવેદનશીલતા નિયંત્રણ

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.

જાળવણી

• સફાઈ: નરમ, સૂકા કપડાથી યુનિટ સાફ કરો. ઘર્ષક ક્લીનર્સ અથવા સોલવન્ટનો ઉપયોગ કરશો નહીં.
• બેટરી રિપ્લેસમેન્ટ: Replace batteries when the low battery indicator appears on the display. Always use fresh AA batteries.
• સંગ્રહ: Store the tuner in a cool, dry place away from direct sunlight and extreme temperatures.

મુશ્કેલીનિવારણ

• કોઈ શક્તિ નથી: ખાતરી કરો કે બેટરી યોગ્ય રીતે ઇન્સ્ટોલ કરેલી છે અને ખાલી નથી થઈ ગઈ. જો જરૂરી હોય તો બદલો.
• 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.
