User Precautions
The laser emitted by this rangefinder is 1535nm, which is safe for
human eyes. Although it is an eye-safe wavelength, it is advised
not to look directly into the laser.
When adjusting the parallelism of the optical axis, be sure to
cover the receiving lens to avoid permanent damage to the detector
due to excessively strong echoes.
This rangefinder module is not airtight. Ensure that the relative
humidity of the environment is below 80% and maintain a clean and
sanitary environment to prevent damage to the laser.
The range of the rangefinder is related to atmospheric visibility
and the nature of the target. Range will be reduced in fog, rain,
and sandstorms. Targets like green tree clusters, white walls, and
exposed limestone have better reflectivity and can increase range.
Additionally, increasing the angle of the laser beam to the target
will reduce the range.
Do not emit lasers at highly reflective targets such as glass or
white walls within 20 meters to avoid echo overstrength and damage
to the APD detector.
Do not plug or unplug cables while the device is powered on.
Ensure the correct polarity of the power supply connection to avoid
permanent damage to the equipment.
