2. Considerations and Safety Maintenance
Please read the instructions carefully so as to ensure accurate measurement results and
safety:
Do not use the device under explosive, flammable or corrosive environment.
Since the product is a precision electronic and sensitive optical device. Do not
impact and drop it to avoid damage.
Do not dismantle and remodel the products.
When the product works, there is a tiny clicking sound for every several seconds.
This is a normal phenomenon as the lens captures images to produce electronic
noises.
Please use damp cloth or weak soap to clean the enclosure of the device. Do not
use abradant, isopropanol or solvent to clean. Special optical lens cleaner should
be used to clean the screen.
