Why does the light on my RovyVon E10 Max (E10MAXB) turn off immediately after double-clicking the scroll wheel, even though the batteries are charged and it is unlocked?

Based on the RovyVon E10 Max (E10MAXB) manual, here are the potential reasons and steps to resolve why your light will not stay on:Check for Overheating: The flashlight has an automatic dimming and protection feature. If the device is too hot, it may shut down or dim significantly. Check the OLED display for a "Hot" icon. If visible, turn the light off and let it cool for 5 minutes.Verify Constant On vs. Momentary On: Ensure you are performing a quick, distinct double-click on the scroll wheel. A single press and hold activates "Momentary On," which turns the light off as soon as you release the wheel.OLED Status: Look at the OLED display when you double-click. If the display flashes 3 times or shows a Lock icon, the device is still locked. To ensure it is fully unlocked, press and hold the left button for 5 seconds until the unlock icon appears.Battery Polarity: Even if charged, if one battery is inserted incorrectly, the circuit may be unstable. Re-open the battery compartment and ensure both batteries match the polarity markings.Contact Support: If the light continues to shut off immediately despite being unlocked and cool, there may be an internal fault. The E10 Max comes with a 2-year manufacturer's warranty; you should contact RovyVon customer service for a potential replacement.
