WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:

Do not open

• This instrument contains no user-serviceable parts. Do not open the instrument or attempt to disassemble or modify the internal components in any way. If it should appear to be malfunctioning, discontinue use immediately and have it inspected by qualified Yamaha service personnel.

Water warning

• Do not expose the instrument to rain, use it near water or in damp or wet conditions, place it on any containers (such as vases, bottles, or glasses) containing liquids that might spill into any openings. If any liquid such as water seeps into the instrument, turn off the power immediately and have the instrument inspected by qualified Yamaha service personnel.

If you notice any abnormality

• When one of the following problems occur, immediately turn off the power and remove all batteries from the instrument, then have the instrument inspected by Yamaha service personnel.
• It emits unusual smells or smoke.
• Some object has been dropped into the instrument.
• There is a sudden loss of sound during use of the instrument.

CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others or damage to the instrument or other property. These precautions include, but are not limited to, the following:

Connection

• Before connecting the instrument to other electronic components, turn off the power for all components. Before turning the power on or off for all components, set all volume levels to a minimum.
• Be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level.

Location

• Do not place the instrument in an unstable position where it might accidentally fall over.

Handling caution

• Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive force on the buttons, switches or connectors.
• not use the instrument/device or headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.

Replacing the Batteries

1. Slide the tab on the endpin section in the direction indicated by the arrow in the diagram below to release the lock, then pull out the battery holder.
2. Insert two AA batteries making sure that the battery poles are properly aligned with the polarity markings on the battery holder.
3. Slide the battery holder back into the endpin section until it locks.

When using nickel-metal-hydride batteries, take care not to damage the battery casing or poles when installing and removing the batteries.

Controls

The built-in preamplifier is automatically turned ON when a guitar cable is connected to the output jack. Always set the volume to its minimum level when connecting or disconnecting the cable.

1. Volume Control
   Controls the volume.

3. 2-Band Equalizer (Bass, Treble)
Level adjustments for the low frequency (Bass) and high frequency (Treble) ranges.

4. Mic Type Switch (Mic. type 1/2)
   Selects the simulated mic type used in the SRT function. Each press of the switch (Blend knob) toggles between Mic. type 1: Condenser and Mic. type 2: Ribbon.

5. Blend Control
   Controls the mix level of signals received from the pickup and the simulated mic. Rotate fully to the left for 100% pickup signal and fully to the right for 100% simulated mic signal.

6. AFR (Auto Feedback Reduction) Switch
   If you experience problem feedback while performing, follow the AFR setting instructions below to effectively control the feedback.

   • When feedback occurs, press the AFR switch (Bass control knob) after all sound other than the feedback has been muted.
   • The system automatically detects the frequency causing the feedback and applies a –12dB cnotch filter.
   • The system may not be able to detect the problem frequency if two or more sounds are present at the same time.
   • Pressing this switch when the AFR system is active (w LED is lit green) switches the AFR function OFF. Alternatively, switch off the power (unplug cable from output jack) to cancel all notch filters

7. Sound Hole Cover (included)
   Inserting the sound hole cover into the sound hole effectively reduces feedback.
