8.Hand crank instructions
The hand-cranked power generation charging function is for
emergency backup charging only. Note: Please power off when
cranking the handle for power generation.
Please follow the diagram to remove the hand crank. Rotate it
clockwise for 10 minutes to activate the internal battery for initial
use. During charging, the battery symbol on the display will flash.
Generate power by rotating the handle at 130-150 RPM for 30
minutes. The internal battery will then have a capacity of
300mAh.
9.Solar Power Generation instructions
Position the device's solar panel directly towards sunlight. The
battery symbol on the display will flash during charging.
Continuous charging under strong sunlight (direct exposure to the
solar panel) for approximately 5 hours can provide up to 1 hour of
continuous flashlight operation.
Note: Charging must be done under strong sunlight; a glowing
red light in weak light conditions indicates light detection but not
charging (e.g., under indoor lighting).
Therefore, do not attempt to charge in low-light conditions. Note:
Please power off the device during solar charging.
