DANGER
- When charging the battery, use the specified charging cable. Using any other items may lead to fire, overheating, leakage, or damage to the connected PC.
- Prevent the charging cable from getting wet and do not touch or hold it if it is wet or if your hands are wet. Failure to do so may result in operational problems or electric shock.
- Use an AC adapter with a USB port with a voltage of 5.0 V DC and a current of at least 1.0 A DC. If you use an adapter with a current value less than 1.0 A, the AC adapter may overheat and cause fire, smoke, overheating, damage, electric shock, or burns.
- Do not heat the battery or expose it to fire. Failure to do so may result in the battery burning or rupturing.
- Do not use or leave the battery in hot or humid places where the battery may be exposed to direct sunlight, in a closed vehicle on a hot day, or near a heater. Failure to do so may result in leakage, overheating, or rupture, leading to fire, burns, or other injuries.
- Do not deform, modify, or disassemble the battery. Also, do not directly apply solder to the battery terminals. Failure to do so may result in leakage, overheating, or rupture, leading to fire, burns, or other injuries.
- Do not touch metal terminals with metal objects, such as hairpins. Failure to do so may result in short circuits, overheating, burns, or other injuries.

WARNING
- Do not disassemble or modify the product. This may cause the product to malfunction, you may fall unexpectedly and suffer serious injury.
- When connecting or disconnecting the USB cable or charging cable, always grasp the cable plug. Failure to do so may result in fire or electric shock.
- If the following symptoms occur, stop using the device and contact the place of purchase. Fire or electric shock may occur.
- If acrid smelling smoke comes from the power plug or the plug gets hot. There may be a bad connection inside the power plug.
- If it thunders while charging with an AC adapter with a USB port, do not touch the device, bicycle, or AC adapter. Electric shock may occur if struck by lightning.
- Do not use a USB hub to connect the cable to the PC's USB port. Charging failure or fire due to overheating may occur.
- Be careful not to damage the charging cable. Do not damage it, modify it, forcibly bend it, twist it, stretch it, place it near hot objects, place heavy objects on it, or tightly bundle it. If used in a damaged state, fire, electric shock, or short circuit may occur.
- If the battery is not fully charged within 4 hours of charging, stop charging. Failure to do so may result in fire, rupture, ignition, or overheating.
- Do not immerse the product in fresh or salt water and prevent the terminals from getting wet. Failure to do so may result in fire, rupture, ignition, or overheating.
- Do not expose the product to strong impact or throw it. Failure to do so may result in rupture, overheating, or operational problems.
- Do not use the battery if it shows fluid leakage, discoloration, deformation, or other atypical signs. Failure to do so may result in rupture, overheating, or operational problems.
- Regularly clean the chain and QUICK-LINK quick connector with a suitable chain cleaner. Maintenance intervals depend on usage and riding conditions. Never use alkaline or acid-based solvents, such as rust removers. If such a solvent is used, the chain or QUICK-LINK quick connector may break and cause serious injury.
- Check that the chain is not damaged (deformation or cracking), skipping, or showing any other irregularities, such as arbitrary gear shifting. If any problems occur, contact the place of purchase or a distributor. The chain may break and you may fall.

CAUTION
- Store in a safe place out of reach of small children to prevent accidental ingestion.
- Prevent grease from adhering to metal terminals. This may cause conduction failure.
- Do not leave the charging cable connected during maintenance.
