Setup
Follow these steps to set up your Donner DT Deluxe Tuner Pedal:
- Power Connection: The pedal can be powered via a standard 9V DC power adapter (center negative) or a USB cable. Connect the appropriate power source to the '9V DC' or 'USB' input on the pedal. Ensure the power supply meets the pedal's requirements to prevent damage.
- Instrument Connection: Connect your guitar or bass to the 'INPUT' jack on the side of the pedal using a standard 1/4-inch instrument cable.
- Amplifier/Effects Chain Connection: Connect the 'OUTPUT' jack of the tuner pedal to your amplifier or the next pedal in your effects chain using another 1/4-inch instrument cable.
- Placement: Due to its small footprint, the DT Deluxe tuner can be easily integrated into crowded pedalboards. Position it conveniently for easy access to the footswitch.

Operating Instructions
Using your Donner DT Deluxe Tuner Pedal is straightforward:
- Activating the Tuner: Tap the footswitch to engage the tuner. The display will illuminate, indicating that the tuner is active. When the tuner is active, the audio signal to your amplifier will be muted, allowing for silent tuning.
- Tuning Your Instrument: Pluck a single string on your instrument. The large LED display will show the detected note and indicate whether it is sharp, flat, or in tune. Adjust your instrument's tuning pegs until the display shows the correct note and the tuning indicator is centered.
- Accuracy: The DT Deluxe tuner provides a fast and precise strobe mode with an accuracy of ±1 cent, allowing for highly accurate tuning.
- True Bypass: When the tuner is disengaged (footswitch tapped again), the pedal activates its true bypass circuit. This ensures that your instrument's signal passes directly through the pedal without any coloration or loss of tone, preserving the natural sound of your instrument and other effects.

Maintenance
To ensure the longevity and optimal performance of your Donner DT Deluxe Tuner Pedal, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the pedal's exterior. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish or internal components.
- Storage: When not in use for extended periods, store the pedal in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Disconnect all cables and the power supply before storing.
- Power Supply Care: Always use a compatible 9V DC (center negative) power supply or a certified USB cable. Incorrect voltage or polarity can damage the unit. Disconnect the power supply when the pedal is not in use to prevent unnecessary wear.
- Cable Connections: Periodically check all input and output jacks for secure connections. Loose connections can lead to signal loss or intermittent performance.
