As illustrated, rotate the USB protective cover clockwise to open it, then connect one end of the USB charging cable to the charging port and the other end to a power source (e.g. a USB adapter or other USB charging devices) to begin the charging process.
The charging time in QC Mode is approx. 1h 30min; the charging time in Standard Mode is approx. 2h 30min (Charged via the 5V/2A Adapter). When fully charged, the standby time is approx. 12 months.
Charging Indication: During the charging process, the power indicators will transition gradually from flashing to a steady light, one by one, displaying the battery level. When the battery is fully charged, the 4 power indicators will become steadily turned on.

Note: The product should be recharged when the output appears to be dim or the headlamp becomes unresponsive due to low power.

Connecting to an External Power Supply
The NU45 can be directly powered by an external power supply. When connected to an external power supply, the headlamp will automatically start charging and prioritize using the external power supply.

• Connect: When the headlamp is on, connect one end of the USB cable to the headlamp and the other end to a power supply. The headlamp will flash once to inform the user.
• Disconnect: When the headlamp is on, disconnect the USB cable. The headlamp will flash twice (3 times each) and stop charging. At this point, the headlamp will automatically switch to being powered by its built-in battery.

Sensor Protection Function
When the headlamp is in MID, HIGH, or TURBO, if the built-in optical sensor detects an obstruction ahead, the brightness will automatically decrease to LOW (100 lumens) to prevent overheating and prolong the lifespan of the headlamp. The sensitivity of the sensor may differ due to variations in the color and material of obstructions. Once the obstruction is removed, the headlamp will return to the previous brightness level.
Off: The protective sensor is automatically enabled when the headlamp is powered on. Once activated, you can temporarily disable the sensor by briefly pressing either button. To reactivate the sensor, turn the headlamp off and then on again.

Note:
1. This feature is only available when the headlamp is in MID, HIGH, and TURBO.
2. It is important to keep the front lens clean to ensure that the built-in sensor functions properly to achieve its optimal performance.
