Using the Magicshine ALLTY 600 is straightforward. First, use the Garmin mount to attach the light to your bike's handlebar or helmet. Once it's securely mounted, turn it on by pressing the power button. You can cycle through different lighting modes as per your needs. To charge the light, simply connect it to a power source using the USB - C cable. Remember to use a compatible charger to ensure fast and safe charging. When it comes to maintenance, keep the light clean by wiping it with a soft, dry cloth after each use. Avoid using harsh chemicals or abrasive materials. Since it's IPX7 waterproof, you don't have to worry about light rain or splashes, but try to avoid long - term submersion in water. If you notice any issues with the light, such as a significant decrease in brightness or problems with the charging, it might be time to contact customer support.
