E80 Lens question

NEJE E80 is equipped with 2 high-temperature-resistant (1000°C) protective lenses, which can be replaced. Pay attention to regularly clean the surface oil and foreign matter according to the actual situation of use. Oil and foreign matter sticking to the surface may cause high temperature to soften the lens.

I received my E80 with one lens installed and one spare was included.
Is the installed lens one of the perishable lenses and where do I install the second lens?
Please explain how to use 2 protective lenses.

Thanks You,



One is a spare

Hello Jim,

Thank you for your response. I have watched those tutorials many times and it does not explain where the 2 high-temperature-resistant (1000 C) protecive lenses are, as advertised. But if one protective lense is all that is actually recommended, then I am good.

Let me know if I am still not understanding.

Thanks,

Wulkan
