Body Assembly Instructions

To ensure correct assembly, read this manual carefully before assembly and keep it accessible.

• Remove the main unit from the box and protective cover. Keep packaging materials for half a month.
• Handle the device with care, keeping it raised horizontally. Avoid pinching hands or dropping the device.
• When screwing, tighten gently first, then gradually increase force to avoid damaging screws.
• After tightening, place the device on a flat, stable surface. Avoid placing it on soft or uneven ground, which can cause pedal instability.
• Do not place the main body directly on the floor to prevent damage to the interface, bracket, and bottom panel.
• Check box items, including the screw package, for completeness.
• Caution: Ensure the pedal support bolt is installed correctly. The black plum plastic part of the pedal support handle bolt should touch the ground to support the pedal force.

Installation Steps

Notes

Warning: Comply with the following to avoid serious injury or death from electric shock, fire, or other dangers.

• Do not open or disassemble the piano. No user-repairable parts inside. Contact qualified repairers for issues.
• Avoid exposing the piano to rain or humid places. Do not place containers with water on the piano.
• If the power cord or plug is worn, damaged, or if you smell strange odors or see smoke, turn off power immediately and contact a repairer.
• Ensure power supply voltage is 220V ± 10% AC. Incorrect voltage can cause damage.
• Turn off power and unplug before cleaning. Do not use wet hands or corrosive solvents for cleaning.
• Regularly check the power switch and cord. Ensure the fuse used matches original specifications.

Warning: Follow these rules to avoid damage to users, the piano, or other devices.

• Keep the power cord away from heat sources. Do not over-bend, place heavy objects on, or damage the power cord.
• When unplugging, pull the plug itself, not the cord.
• Unplug the piano when not in use for extended periods or during thunderstorms.
• Avoid dusty, vibrating, hot, or cold environments, or direct sunlight, which can damage the piano's appearance and internal components.
• Disconnect the power cord and other connected wires before moving the piano.
• Clean with a dry, soft cloth. Do not use paint thinner, organic solvents, or detergents that can cause discoloration.
• When connecting to other devices, turn off all power switches first. Set volume to minimum before powering on and gradually increase.
• Do not place the piano near other appliances like TVs or radios to avoid interference.
• Do not place the piano on an unstable surface.
• Do not place heavy objects on the piano or use excessive force on keys/switches.
• The piano has sufficient volume redundancy for classrooms and auditoriums. Adjust volume appropriately. Excessive volume for prolonged periods can cause hearing loss.
• Avoid strong collisions, which can damage the piano and cause personal injury.

Prepare Before Use

This chapter covers function jacks and provides information before playing. Read these items before turning on the power switch.

Power Connection

1. Ensure the power switch is off.
2. Connect the power cord to the DC jack on the back of the piano, then plug the adapter into the power outlet.
3. Set all volume controllers to minimum before powering on.
4. When turning off the power, set all volume controllers to minimum before turning off the power switch.

Warning: Unplug the piano when not in use or during thunderstorms. Ensure the power supply is 220V ± 10% AC. The power socket should be grounded. Do not remove the power cord while the piano is on.

Socket on the Back of the Host

The back of the host features the following ports:

• AUDIO PORT
• MIDI INTERFACE
• USB INTERFACE
• POWER INTERFACE

Headphone Port
