4.2 Tuning Modes
The Korg AWOTGPOLY offers various tuning modes. Refer to the tuner's display for mode indicators.
- Polyphonic Mode: Strum all strings simultaneously. The tuner will display the tuning status of each string, allowing you to quickly identify and adjust any out-of-tune strings.

4.3 Tuning Process
- Power on the tuner and select your desired tuning mode (e.g., Polyphonic or Single String).
- Play the string(s) you wish to tune.
- Observe the OLED display. The display will show the detected note and visual indicators (e.g., a needle, strobe patterns, or color changes) to guide your tuning.
- Adjust the tuning peg of the corresponding string until the display indicates the correct pitch (typically a stable green light or centered indicator).
- Repeat for all strings until your instrument is in tune.
4.4 Calibration
The tuner's calibration can be adjusted to match different reference pitches (e.g., A4=440Hz). Consult the tuner's specific buttons (often marked with up/down arrows or 'Calib') to change the reference pitch.
5. Maintenance
5.1 Battery Replacement
When the battery level is low, the display may dim or the tuner may not function correctly. Replace the AAA battery as described in Section 3.1.
5.2 Cleaning
Wipe the tuner with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or display.
6. Troubleshooting
- Tuner Not Powering On: Check if the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Inaccurate Readings: Ensure the tuner is securely clipped to the headstock and that there is no excessive ambient noise interfering with the vibration sensor. Try plucking the string more clearly. Verify the correct tuning mode (e.g., Guitar mode) is selected.
- Display Issues: If the display is dim or flickering, the battery may be low. Replace the battery.
