Usage Features:

• Initial Setup: Before first use, the user must unscrew the tail cap, remove the battery insulation sheet, and then re-tighten the tail cap. This ensures proper electrical contact and prevents accidental activation during shipping.
• Battery Installation: When replacing the battery, ensure the positive (+) end of the battery is oriented towards the flashlight head (LED side).
• Operation:
  • Default Mode: The flashlight defaults to the low brightness mode upon power-on.
  • Momentary On: Lightly press and hold the tail switch for momentary activation. Release to turn off.
  • Constant On/Off: Fully press the tail switch to turn the flashlight on constantly. Press again to turn it off.
  • Mode Cycling: While the flashlight is on, quickly press the tail switch twice within 2 seconds to cycle between low and high brightness modes.
  • Mode Memory (Limited): If the flashlight is turned off for less than 2 seconds, it will return to the previously used brightness level (low or high) when turned on again. If turned off for more than 2 seconds, it will revert to the default low brightness mode upon the next activation.
• Low Voltage Warning: When the battery voltage is too low (below 1.2V), the flashlight will not be able to reach its maximum output of 300 lumens.
• Safety Precautions:
  • Eye Protection: Do not aim the light directly into human eyes or faces, as it may cause temporary blindness or eye damage.
  • Heat Management: Avoid covering the lit flashlight with objects or placing the flashlight head on the ground, as the heat generated during operation can damage the flashlight or ignite nearby materials.
  • Battery Compatibility: Only use the specified AA alkaline or NiMH batteries. Using other battery types, especially rechargeable lithium batteries not explicitly mentioned, can damage the flashlight or lead to unforeseen hazards.
  • Child Safety: Keep the flashlight out of reach of children.
  • Long-Term Storage: For extended storage periods, unscrew the tail cap and remove the battery to prevent leakage and damage.
