1. Remove the batteries when not in use

It’s easy to forget to take out the batteries when the keychain laser pointer is not in use but be sure to remember to do this. Leaving the batteries can cause corrosion on the battery terminals which could lead to other problems.

2. Keep the lens covered when not in use

Most laser pointers will come with a carrying case or some type of pouch to keep it protected. The lenses of laser devices are extremely sensitive to dust and even a tiny piece can result in a spotted laser beam. Be sure to use the proper cleaning cloths to wipe off any dust on the lens.

3. Store in room temperature

Lasers pointers can become faulty when exposed to extreme heat or cold so be sure to store the keychain laser pointer in room temperature between 0 to 40 degrees Celsius.

These are just maintenance tips for taking care of your keychain laser pointer. Be sure to always handle it with care and to keep safety factors in mind. Be sure never to drop your keychain laser pointer.
