General Operation
While UV mode is active, the blue indicator light on the button remains on.
For stepless dimming (white light): Long press the white light button. Pressing again within 1.5 seconds will reverse the dimming direction (e.g., brighter to dimmer, or dimmer to brighter). Pressing after 1.5 seconds will continue in the same direction. When maximum brightness is reached, the light will flash once to indicate the peak level.
Lock/Unlock Function:
When the flashlight is off, click the white light button 4 times to lock. Click 4 times again to unlock. In lock mode, any button press (except the 4-click unlock sequence) will trigger two flashes to indicate the flashlight is locked.
Battery Level Indicator
After turning on the SR23, the indicator will display the voltage for 5 seconds:
- Solid Green = 75%-100%
- Flashing Green = 50%-75%
- Solid Red = 25%-50%
- Flashing Red = 1-25%
Light Indicator When Charging
- Red = Charging
- Green = Fully Charged
The SR23 features a USB Type-C charging port for convenient charging. Connect it with the included charging cable and use a power adapter (not included) with 5V/2A (max) output.

Warnings
- Do not look directly into the flashlight beam. Avoid direct exposure of UV light to eyes or skin.
- Keep out of reach of children.
- Ensure the battery is installed correctly to avoid damage or leakage.
- Do not expose the flashlight to water or extreme temperatures for prolonged periods.
- Do not use batteries that are not compatible with the flashlight.
- Always remove the batteries if the flashlight will not be used for an extended period.
- Keep the lens clean and free of debris to ensure proper light output.
- Extended use at high brightness will cause significant heat buildup. This is normal operation and not a malfunction.
- When carrying the flashlight, if necessary, enable the lock mode (if available) or slightly loosen the battery compartment to physically cut off the power.
