4 CAUTION

4.1 Ambient Temperature

When the working environment temperature of X4PRO is over high or over low, it will affect
the accuracy of the distance measuring system. It may also damage the structure of the scanning
system and reduce the service life of the X4PRO lidar. Avoid using in high temperature (>50 degrees
Celsius) and low temperature (<0 degrees Celsius) conditions.

4.2 Ambient Lighting

The ideal working environment of X4PRO is indoor, and the indoor environment light
(including no light) will not affect the work of X4PRO. However, please avoid using strong light
sources (such as high-power lasers) to directly illuminate the X4PRO vision system.
If the user need to use it outdoors, please avoid the X4PRO's vision system directly facing the
sun, which may cause permanent damage to the vision system's photosensitive chip, which will
invalidate the range finding.
The X4PRO standard version will cause interference in the distance measurement under the
conditions of strong sunlight reflection outdoors, please pay attention to it.

4.3 Power Supply

During the development process, since the drive current of the USB interface of each platform
or the USB interface of the computer may be too low to drive the X4PRO, the external power supply
of the +5V to the X4PRO needs to be provided through the USB_PWR interface of the USB
interface board. It is not recommended for use mobile phone power bank because the voltage ripple
of power bank is too large.
