Using your Ledlenser H5R Core headlamp is easy. First, charge the battery using the magnetic charging cable that comes with it. It takes about 210 minutes to fully charge. Once charged, you can turn on the headlamp. Use the multi - function wheel switch to adjust the brightness. You can also switch between the Boost, High Power, and Low Power modes depending on how much light you need. The headlamp has a 160 - degree tilting head, so you can point the light in the right direction. There's a transport lock, so when you put the headlamp in your bag, it won't turn on by mistake. And thanks to the memory function, it will turn on to the last setting you used.
When it comes to maintenance, keep it clean. Since it's waterproof and dustproof with IP67 rating, you can rinse it under water if it gets dirty. But don't forget to check the battery life using the battery indicator, charge indicator, and low battery warning. Replace the battery when it's no longer holding a charge well. And always store the headlamp in a cool, dry place when not in use.
