5. Operating Instructions
Using your LT-910 tuner is straightforward:
- Activate Tuner: Press the footswitch once to activate the tuner. The LED display will illuminate, indicating it is in tuning mode.
- Play a Note: Play a single, clear note on your instrument. The display will show the note name (e.g., E, A, D, G, B, E for guitar) and the strobe indicator will begin to move.
- Tune Your Instrument: Adjust your instrument's tuning (tighten or loosen strings) until the displayed note name is stable and the blue indicator light illuminates at the top of the display. The strobe display will stop moving when the note is perfectly in tune.
- Bypass Tuner: Once tuning is complete, press the footswitch again to bypass the tuner. The display will turn off, and your instrument's signal will pass through unaffected due to the true bypass circuitry.
6. Maintenance
To ensure the longevity and optimal performance of your Rowin LT-910 Tuner Pedal, follow these maintenance guidelines:
