Some important notes: Make sure to lock the headlamp using the LOCK function when you're not using it or during storage to avoid accidental activation. Also, since it's IPX4 weather - resistant, it can handle some splashes but don't submerge it in water. For maintenance, keep the headlamp clean and dry. If the headband gets dirty, you can gently wash it. Check the battery regularly and replace it if it doesn't hold a charge well.
