Press down and slide off the lid of the batteries compartment (located on the bottom of the unit). Remove the old batteries from the compartment. Insert two of the same type of fresh AA batteries. * Make sure the “+” and “-” ends of the batteries are oriented correctly. ■ OCTAVE ADJUST Mode To ensure that the correct pitch is played when you press the strings against the guitar frets, Octave Adjust is required. The TU-15 features an OCTAVE ADJUST mode, which indicates whether you need to shift the bridge up or down when the sound of the open string and the sound with the string pressed at the twelfth fret are played. This function allows you to make octave adjustments quickly and easily. First tune the instrument in GUITAR/BASS mode. The “OCT ADJ” in the display lights up, and the tuner switches to GUITAR or BASS mode. In MANUAL mode, you can select the string to adjust by pressing the [NOTE] button. When the pitch stabilizes, “OF” lights up. Next, play the same string while holding it down at the twelfth fret. When a stable pitch is obtained, “12 F” lights up, and the meter indicates the direction in which the bridge should be shifted. If the needle moves to the left side (the side), shift the bridge toward the neck; if the needle moves to the right side (the side), shift the bridge away from the neck. * For instructions on moving the bridge, refer to the owner’s manual that came with your guitar. After shifting the bridge, repeat Steps 3 and 4. This adjustment is complete when the meter is at 0 (center) while “12 F” is lit. When you have finished adjusting all of the strings, press the [OCT ADJ] button to exit OCTAVE ADJUST mode. + - MIC Use this when tuning acoustic instruments. Position the mic as closely as possible to the instrument. Do not connect anything to the INPUT or OUTPUT jacks when using the mic.
