Battery Replacement

As battery power becomes low, the battery check indicator will light. Replace the batteries as soon as possible.

1. Press the release lever on the battery case in the direction indicated by the arrow [➡️] in the illustration to unlock it, and then slide out the battery holder.
2. Remove the old batteries from the battery holder, and insert two new size AA alkaline batteries. Make sure that the poles on the batteries are properly positioned as shown in the diagram inside of the holder.
3. Slide the battery holder back into the battery case and press firmly so that the battery holder locks in place.

Diagram Description: The illustration shows the battery compartment with a release lever, battery holder, and space for two AA batteries. Arrows indicate the direction to press the lever and slide out the holder.

Nomenclature/The Controls

Diagram Description: The diagram shows the guitar's control section, pickup section, and output jack. The control section features knobs and switches. The output jack is described as having a power switch function.

• VOL Control: Controls the volume. Always set the volume to its minimum level when connecting or disconnecting the cable.
• BATT. (Battery Check) Indicator: This indicator will light when the battery needs to be replaced. Please replace the battery as soon as possible when the BATT. indicator lights. (Note: The battery check indicator may light momentarily when the TUNER switch is pressed; this is not a sign of low battery power.)
• 3-Band Equalizer:
  • LOW: Boosts or cuts the level of the low frequencies.
  • MID: Boosts or cuts the level of the middle frequencies. The AMF control adjusts the center frequency of the band affected by this control.
  • HIGH: Boosts or cuts the level of the high frequencies.
• AMF Control: Sets the center frequency of the band of frequencies affected by the MID equalizer control. The range is from 80 Hz to 10 kHz. This control has no effect when the MID equalizer control is set to its center position.
• Tuner Display: Displays tuner information.
• TUNER Switch: Switches the tuner ON/OFF.

Using the Tuner

1. Press and hold the TUNER switch until the display lights to switch the tuner power ON.
2. Tune the guitar string until the note name of the desired pitch appears in the display.
3. The string is in tune when only the lamp lights in the center of the display.
   • Pitch is low: [⬇️]
   • In Tune: [✅]
   • Pitch is high: [⬆️]
4. Press the TUNER switch again to switch the tuner power OFF. Also, if the note name is not shown in the display for more than 1 minute, the power will automatically switch OFF (display goes off).

Notes on Tuner Use:

• It may take a few seconds before the tuner can detect pitches after being switched ON.
• The note name and pitch displays may have difficulty keeping up with irregular pitch changes. Gradually change the pitch and check when tuning.

• Sound output is not muted when the tuner is being used.
