2. Basic operation and precautions
This chapter explains the basic operations and precautions involving personal safety
and equipment safety. Please read it carefully before using the AS-21C.
2.1 Correct method of use
AS-21C is an optical sensor for non-contact distance measurement. It can be used
alone, or it can be used on the network. It is mainly used to accurately measure the
surrounding environment and target contour, and it can also be used to build safety
precautions. Security protection, positioning and navigation applications.
The AS-21C can only be operated by professionals and used in a compliant
environment.
Important note
For the requirements of the AS-21C use environment,
please read "10.1 Data Book".
2.2 Incorrect usage warning
AS-21C can only be used for safety warning purposes and cannot physically
protect personal safety in hazardous environments.
AS-21C cannot be used in hazardous environments with explosive hazards.
The use of accessories not provided by AkuSense is at the user's own risk.
2.3 Networking instructions
The AS-21C uses standard TCP/IP technology for device networking. When actual
networking, you need to ensure the following prerequisites:
Users need to ensure the integrity and confidentiality of the data transmitted on
the network.
Necessary network security measures, such as network isolation, firewalls, and
anti-virus software, need to be planned and implemented by users themselves.
2.4 Disclaimer of equipment damage
AkuSense is not liable for equipment damage due to the following reasons:
Did not read the manual carefully.
Failure to properly use the equipment as required.
Operated by unqualified personnel.
Equipment dismantling without AkuSense approval.
Modification of equipment without AkuSense approval.

Technical transformation of the equipment.
Use self-made accessories.
2.5 Laser radiation instructions
AS-21C is measured with an infrared laser with a wavelength of 905 nm. The laser
beam is invisible to the naked eye.
Cautious operation
AS-21C meets the requirements of a class of laser safety
levels as specified in GB 7247.1-2012. Under normal
conditions of use, it is harmless to the human eye and the
skin. However, incorrect use of the AS-21C may bring
security risks. The matters are as follows:
Do not open the cover of the AS-21C. The powered
AS-21C will not stop laser firing when the cover is
opened.
Do not look directly into the laser output side of the
AS-21C for a long time, especially children, and
may cause blindness.
The laser output surface of AS-21C is an optical transmissive cover. The laser
warning mark is located on the top cover of the device, as shown in "Figure 2.1 Laser
output surface and laser warning sign".

2.6 Power supply and quick start and stop
The AS-21C is powered by the DC002-type circular waterproof power socket in the
interface cable on the side of the device, as shown in the “Figure 2.2 Power Outlet”. the
power supply voltage is 10V~28V DC, and the power is in normal operation. The power
