Safety Precautions

Before using, please read the following items carefully and keep this document in a safe place for future reference.

Warning

When using the product, please comply with the following items to operate, so as to avoid serious injuries or death to users due to electric shock, short circuit, accident, fire or other dangers. Pay attention to the following, but not limited to these:

• Do not open the electric piano or attempt to disassemble components, and do not make any changes to the inside. This product does not have parts that users can repair themselves. (The electronic piano has an automatic temperament stabilization system, so tuning is unnecessary). If there is dysfunction, please contact qualified repairers for checking and maintenance.
• Avoid exposing the electronic piano to rain, or using it near watery and humid places. Do not place containers with water on the electronic piano, as moisture may flow into the interior.
• If the power cord or plug is worn or damaged, or if power is suddenly cut off during use, and you smell a strange odor or the electronic piano emits smoke, turn off the power immediately, remove the power plug, and ask a qualified repairer for checking and maintenance.
• Ensure that the power supply voltage is 220V ± 10% AC; too high or too low voltage will cause damage to the piano.
• Before cleaning, turn off the power and remove the power plug. Do not operate with wet hands while electricity is used. Do not wipe and clean the electronic piano with corrosive solvents.
• Regularly check the power switch and the power cord. When changing the fuse, ensure that the power plug is removed and use the same fuse with the original specifications.

Warning

Users should also obey the following rules during use, which can avoid damage to users or others, and the electronic piano or other external devices. The items that users need to pay attention to are shown as follows, but not limited to these:

• Do not place the AC power cord near heat sources, such as a heater. Do not over-bend the power cord, put heavy objects on it, place it where people walk, or wrap other things around it to avoid damage.
• When removing the power plug, take the plug itself, not pull the cord.
• Remove the power plug if the electronic piano will not be used for a long time or during thunderstorms.
• Do not place this electronic piano in a dusty, vibrating, cold, or hot environment (such as under direct sunlight, near a heating device, or in a vehicle in the sun) to avoid damaging its appearance and internal components.
• Before moving, remove the power cord and any connected wires.
• When cleaning, wipe with a dry, soft cloth. Do not use paint thinner, organic solvents, detergents, or other chemicals with an erosive effect to avoid discoloration of the panel or keyboard.
• When connecting to other devices, first turn off all power switches. Before turning off the power switch, set the volume to its minimum. When using the instrument, first set the electronic piano's volume to its minimum, then gradually increase it.
• Do not place the electronic piano near other appliances, such as TVs, radios, speakers, etc., as this may cause interference.
• Do not place the electronic piano in an unstable place to prevent it from falling.
• Do not place heavy objects on the electronic piano, and do not use excessive force to press the keys or toggle control switches.
• To suit occasions like classrooms and auditoriums, this electronic piano has sufficient volume redundancy. Adjust the volume to a proper value. Prolonged use at unreasonably high volumes is not only musically inappropriate but may also cause hearing loss.
• Avoid strong collisions with the electronic piano, as they may cause damage and personal injury.

Prepare Before Use

This chapter introduces the function jacks and provides information before playing. Before turning on the power switch, please read the following items.

Power Connection

1. Confirm the power switch is off. If not, turn it off.
2. Connect the power cord: insert the plug into the DC jack on the back of the electronic piano, then plug the other end of the power adapter into the power outlet.
3. Before turning on the power, adjust all volume controllers to the minimum.
4. When turning off the power, first turn all volume controllers to the minimum, then turn off the power switch.

Warning: When not in use, or during thunderstorms, remove the power plug. Ensure the power supply voltage is 220V ± 10% AC; incorrect voltage can cause damage. The power socket should be a triangle and grounded. Do not remove the power cord from the socket while the electronic piano is on.

Sockets on the Back of the Host

The back of the host features:

• Audio Port (4 RCA jacks)
• MIDI Interface (2 x 5-pin DIN connectors)
• USB Interface (Type B connector)
• Power Interface (DC IN jack)

Headphone Port

Located on the bottom left side of the host.

Three-Pedal Interface

Connects to the three-pedal unit.

Three-Pedal Unit

Modeled after traditional grand pianos, this unit includes a damper pedal, a sostenuto pedal, and a soft pedal.

• Press the pedal to activate; release to deactivate.
• Connect the pedal cord to the pedal connector at the bottom of the piano.

Damper Pedal (Right)

When depressed, notes are sustained. Releasing the pedal immediately stops the sustain effect. If you press the damper pedal, the currently played notes and previously played notes will sustain longer.

Sostenuto Pedal (Middle)

Press and hold a note key while depressing the pedal to sustain that specific note (like the damper pedal) without affecting subsequent notes. This allows for sustaining chords or bass notes while playing other parts staccato.

Soft Pedal (Left)

Depressing the soft pedal reduces the volume of played notes and alters the timbre. Notes played before the pedal is depressed are unaffected.

Caution: Before pressing the pedal, ensure the pedal support screw is installed and fully grounded.
