Charging

• Loosen the light body to reveal the Micro USB port; plug the USB-A end into an outlet and connect the Micro USB end to the light.
• Indicator glows red while charging and turns green when fully charged.
• Tighten the light head once charging completes to maintain dust/water resistance.
• Normal charging time is about 1 hour from depleted to full. Recharge a stored light every four months.

Intelligent Overheat Protection

The light steps down output automatically once it reaches 60°C or above on High mode; it re-allows reselection of High once cooled below 60°C.

Usage and Maintenance

• Disassembling the sealed head can damage the light and voids the warranty.
• Lock the light to prevent accidental activation during storage or transport.
• Long-term use can wear the O-ring; replace with an approved spare to maintain a proper water seal.
