Proper maintenance and care of this product play a very important role in extending its service life and reducing malfunctions.

1. Do not open the electronic keyboard’s casing or attempt to disassemble its components, and do not make any modifications to the interior. If any malfunction occurs during use, stop using it and have it inspected by qualified service personnel.

2. Please use the specified voltage and adapter. Using the wrong voltage or adapter may damage the electronic keyboard.

3. Do not place the power adapter near heat sources (such as heaters or radiators). Do not excessively bend the adapter cable, place heavy objects on it, or wrap it with other items, as this may damage the cable.

4. Do not plug the electronic keyboard into a multi-socket outlet to avoid overheating. When not in use for a long time or during thunderstorms, turn off the power and unplug the adapter. When unplugging, hold the adapter itself instead of pulling the cable directly.

5. Do not place the electronic keyboard in dusty, vibrating, low-temperature, or high-temperature environments (such as direct sunlight, near heaters, or inside a car under sunlight), as this may damage the exterior and internal components.

6. Do not place the electronic keyboard on an unstable surface to avoid damage from falls. Do not sit on the keyboard or place heavy objects on it.

7. Avoid exposing the electronic keyboard to rain or moisture. Do not place containers with liquids on the keyboard to prevent liquid from entering and damaging internal components.

8. Before cleaning the keyboard, unplug the adapter. Use a dry, soft cloth to wipe the body. Do not use paint, organic solvents, or chemically treated cloths. Do not place vinyl or plastic items on the keyboard to avoid discoloration of the panel or keys.

9. In humid weather, take precautions against moisture, as excessive humidity can cause internal circuit issues. During humid weather, the keyboard should be powered on regularly so that the heat generated during operation evaporates moisture inside the keyboard. In highly humid conditions, a dustproof and moisture-proof cover can be used to protect the keyboard.

10. The packaging must be opened and the product used by adults only. After removing the product, properly store this plastic packaging bag.

Proper maintenance and care of this product play a very important role in extending its service life and reducing malfunctions.

Preventing Bumps

Using a stand or placing the ukulele in its case after use can ensure that it is less likely to be knocked over or damaged, and the body is less likely to get scratched. Never just throw the ukulele around.

Long-Term Non-Use

When not using it for a long time, slightly loosen the strings to prevent long-term tension from causing the back of the bridge to lift, which can affect tuning.

Cleaning and Wiping

Playing leaves sweat and oils on the instrument. Remember to clean the body, fingerboard, strings, and other parts with a cleaning cloth. Keeping the ukulele clean can effectively extend its lifespan. (Avoid using alcohol or corrosive chemicals for cleaning!)

Moisture and Sun Protection

It is important to protect the instrument from moisture and sunlight. For wooden instruments, the primary concern is preventing humidity and sun exposure. When not in use, try to keep the ukulele in a cool, dry place to avoid warping or cracking from moisture or direct sunlight.

Best Maintenance Method

The best way to maintain it is to play it regularly.

Proper maintenance and care of this product play a very important role in extending its service life and reducing malfunctions.

1. Do not place or use the metronome in unclean, damp areas or under direct sunlight.

2. Never remove the pendulum from the metronome to prevent children from swallowing it.

3. When not using the metronome, always secure the pendulum on the pendulum holder; otherwise, the tip of the pendulum may cause injury.

4. Do not place the metronome unstable on high shelves or similar elevated places. If the metronome falls from a height, it may break, and the fragments could cause injury.

5. After use, always return the pendulum to the pendulum holder and cover it with the casing. When covering, first secure the bottom part of the casing onto the metronome body, then push the top part to fit completely. To remove the casing, hold it and pull outward.

6. When cleaning the metronome, use a soft cloth moistened with a neutral cleaning solution. Do not use volatile solvents such as paint thinner or benzene.

Proper maintenance and care of this product play a very important role in extending its lifespan and reducing malfunctions.

1. Avoid using in harsh environments such as high temperatures, humidity, direct sunlight, strong light, extreme cold, or near magnetic fields;

2. The metronome casing is made of ABS material and should not be subjected to heavy pressure;

3. The metronome contains circuits and should not be disassembled privately;

4. For battery-operated models, remove the batteries if not used for a long time to prevent battery leakage and internal corrosion;

5. For rechargeable models, avoid prolonged charging to prevent affecting the battery's lifespan;

6. This product still consumes a small amount of power in sleep mode.

Friendly Reminder: Batteries may experience aging after long-term use, such as a reduced charge capacity, leading to shorter battery life and decreased peak performance. 

Following the suggestions below can extend battery life by 1-2 years. "Avoid extreme conditions"—through scientific charging habits, reasonable usage environments, and careful feature management, you can keep your device performing at its best.

1. Charging Habits

1) Power Management: Charge your device even if the battery is not fully depleted. Disconnect the charger when fully charged and keep the battery level between 20%-95% to avoid overcharging or deep discharging.

2) Choice of Charging Equipment: Use original or 3C-certified chargers and avoid counterfeit products.

3) Long Periods of Inactivity: If the device will not be used for a long time, turn it off and keep the battery level at 40%-50%.

2. Charging Environment

1) Temperature Range: The optimal operating temperature is 16°C-22°C. Avoid charging in environments above 35°C or below 0°C, as this may permanently reduce battery lifespan.

2) Usage Environment: Avoid using the device for extended periods in high-temperature or high-humidity conditions.

3. Health Maintenance

1) Unplug the charger once the device is fully charged. Do not use the device while charging after it is full, as this accelerates battery aging due to repeated charge cycles. When not in use, turn off the device to prevent deep discharge that can damage battery life.

2) Avoid frequent plugging and unplugging of the charger. Each instance generates a current spike, and excessive repetition can affect the lifespan of the battery protection circuit.
