Risk of death; Prevention of accidents

Do not look directly at the light source. In addition, when mounting the light unit, ensure that the light would not dazzle other road users.
To prevent accidents and to ensure safe riding, make sure the light is securely attached to the bracket and it is functioning properly without being unobstructed before the ride.
Always pay attention to the remaining battery power by checking the indicator periodically while using the light.
Do not disassemble or modify the light or any of the included items.

Prevention of injury, damage, or property damage

Be sure to tighten the dial by hand. When you tighten it too hard with a tool, the screw thread may be stripped.
Check the dial and screw on the bracket periodically, and use them without any loosening.
Operating the light while riding is dangerous. Always ride safely.
Do not use Ultra Boost or High mode on public roads.
Note that the light becomes hot while illuminated. Do not block the lens or cover the light.
Due to the variability of LEDs, the color and brightness may differ even between devices with the same model number.
Keep devices out of the reach of children.
Carrying a spare headlight is recommended in case the battery runs out.
When used with a cyclo-computer, attach the headlight as far away from the cyclo-computer as possible, as it may affect the measurement.
This device is rated IPX4 based on JIS C0920. Do not immerse the device in water. Doing so may cause a malfunction. Wipe off any moisture after using the device in rainy weather.
Do not subject the light to strong vibrations, impacts, or excessive force. Discontinue use if any abnormality occurs.
Do not charge or use the battery at any voltage or polarity other than that specified. Do not short-circuit the battery.
Do not drop the light into a fire or heat the light.
If the light unit or parts become dirty with mud, etc., clean them with a soft cloth moistened with mild soap. Never apply paint thinner, benzine, or alcohol; damage will result.

LITHIUM-ION BATTERIES

Recharge the battery for first-time use or after a long period of storage:
The voltage of the battery may drop due to self-discharge during long periods of storage.

Always fully charge the battery before use.
If the device will not be used for a long period, store it in a location that is not too hot or too humid.
Charge the battery for about 30 minutes every 6 months.

Cautions for charging and usage:

Charging, discharging, and storing in high temperatures will cause the rechargeable battery to deteriorate faster. Do not place the light inside a vehicle or near a heater. Make sure to charge only when the ambient temperature is between 5 and 40°C.
Please be sure that no dust or other foreign objects are attached to the plug of the USB cable before charging.
Do not apply a load to the connector port by hanging the light unit during charging.
Do not subject the light to vibrations while charging.
Once charging is completed, be sure to disconnect the USB cable from the charging port.
After charging is complete, securely attach the charging port cover to ensure waterproofing before riding.
Charging and lighting times are approximate values and will vary by environmental and user conditions.
If the illumination time is significantly reduced even after proper charging, the rechargeable battery may be nearing the end of its service life.

Cautions for dispose:
When disposing of the light unit, please do so under your local regulations.
