Before using this unit, carefully read the sections entitled: "USING THE UNIT SAFELY" and "IMPORTANT NOTES" (supplied on a separate sheet). These sections provide important information concerning the proper operation of the unit.
Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference.

Main Features
- High Brightness mode enhances meter visibility outdoors.
- Accu-Pitch Sign function uses the motion of the meter's lights to show when tuning is completed.
- Guitar/Bass mode lets you tune by string number, with support for 7-string guitars and 6-string basses.
- Flat tuning is supported with Guitar Flat mode, which allows for "down" tunings up to six semitones below standard pitch.
How to Use the Tuner
- Connect the AC adaptor (sold separately). This switch on the sensor of the FUSEC indicators
- Connect the guitar or bass you want to tune to the INPUT jack.
- Play a single note on your guitar or bass, and tune it.
The note name or string number closest to the tone being played appears in the display. Tune the instrument so that both Tuning Guide indicators are lit and the center of the meter is lit green. (Cent display)
The meter will light farther toward the left as the pitch gets flatter, or farther toward the right as the pitch gets sharper.

- When the Accu-Pitch Sign function is on, the meter lights stream toward the center of the display when stable tuning at the correct pitch is reached.
- The meter behavior described here is when the CENT display is selected (the factory setting). The behavior is different when you've selected the STREAM display.
