Precautions for the use of hand-held laser rangefinders
1. Pay attention to the positive and negative poles when installing batteries and only use alkaline batteries.
2. Do not point the laser of the machine directly at the sun, eyes or irradiate the eyes through reflective surfaces (such as mirror reflection) during measurement.
3. It must be handled with care during use, and it should be avoided in places with excessive humidity, high temperature or direct sunlight.
4. The sun is too strong, the ambient temperature fluctuates too much, the reflection effect of the reflective surface is weak, and the measurement result will have a large error in the case of insufficient battery power. In this case, it is better to use the target reflector.
