precautions
1. Battery installation method: the positive electrode of the laser pen battery faces the tail of the laser pen.
2. Laser beam is absolutely not allowed to face when using human and animal eye exposure!
3. It is recommended that the continuous lighting time of the laser should not exceed 3 minutes. If not, the lifetime of LD will be affected due to overheating!
4. Please take out the battery when not in use and put it in a place that is not easy for children to get!
5. If brightness of laser beam is seriously reduced, please pay attention to charging the battery or replacing the battery.

Usage:
1. Unscrew the back cover of laser flashlight.
2. Place the positive pole of one 16340 Battery facing outward (at the switch), and place the negative pole facing inward (at the head of the light outlet), then twist the back cover.

3. After the laser flashlight is turned on, turn the focusing head, and the light spot becomes larger, which will form a focus on the beam near the light outlet. The larger the light spot, the closer the focus is to the light outlet, at this time, you can burn things when you find the focus (note: The moving Range of the focus on the beam is limited. Beginners may not be able to find the focus so that sometimes they cannot ignite, so they need to be more familiar with it, before sending our product to you, we will test the relevant functions before sending it out).
4. When the light spot is the smallest, the light beam is parallel light and cannot burn things.
5. When not in use for a long time, please take out the battery.

• Tips: in order to achieve the display effect, our laser pen use the same picture and light column effect regardless of the power, please know, please refer to the brightness of the power you actually purchased!
