- Constant On/Off: Fully press the tail switch until it clicks to turn the flashlight on or off.
5.2 Mode Switching
When the flashlight is ON:
- Cycle Modes: With the flashlight ON, lightly tap the tail switch (without clicking) to cycle through the main brightness modes: Low → Medium → High.
- Special Modes:
- Strobe: From OFF, fully press and hold the tail switch for approximately 1 second to activate Strobe mode. Release to turn off. From ON, a quick double-tap of the tail switch (without clicking) may also activate Strobe.

Proper maintenance ensures the longevity and optimal performance of your APLOS T03 flashlight.
- Cleaning: Clean the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents.

- Threads: Keep the threads of the tail cap clean and lightly lubricated to ensure smooth operation and proper electrical contact.
- Battery Care: If the flashlight will not be used for an extended period, remove the battery to prevent potential leakage or damage. Store the battery in a cool, dry place.
- Charging Port: Ensure the USB-C charging port cover is securely closed when not charging to prevent dust and water ingress.
