How to install the headband on the headlamp?

The installation method is as follows:
Generally, there will be two elastic bands on the headlamp, one short and one long. The long band has relatively small horizontal holes at both ends, and the short band has a wide horizontal hole at the first level. When installing, pass the long band through the short band hole to make a T shape. After passing through, make sure that the lengths on the left and right are roughly the same, and put this elastic band directly on your head.
After the headlamp is installed with the headband and worn on the head, it can also be adjusted through the elastic band. It can be adjusted according to the size of your head circumference. Be careful not to be too tight or too loose.
