What should be paid attention to when using public broadcasting?
Release date: 2020-04-28 22:13
Now in our life, in many cases, we enjoy the convenience of public broadcasting. There are a lot of new information we will get in the first time through public broadcasting, and there will be many opportunities in it. But while enjoying the benefits of public broadcasting, we should also pay attention to the safety precautions when using public broadcasting:
1、 Pay attention to the operating conditions of the machine
Special attention shall be paid to the following items: avoid using the machine in extremely low or extremely high temperature environment, avoid direct sunlight on the surface of the machine all the time; avoid using the machine in humid environment, so as to avoid premature failure of components in the machine or premature rust of the machine; before using, make sure that the local power supply voltage is consistent with the machine.
2、 Pay attention to the operating environment of the machine
Avoid using the machine in dust and vibration environment; leave enough space around the machine to facilitate the heat dissipation of the machine; for power amplifier, pay special attention to keep the heat dissipation channel unblocked.
3、 Points for attention in the use of the machine
In the use process, attention should be paid to the order of power on and power off. When the power is turned on, the power amplifier shall be turned on after the pre equipment such as sound source; when the power is turned off, the power amplifier shall be turned off before the pre equipment such as sound source. If there is a volume knob on the audio equipment, it is better to turn the volume knob to the minimum before starting and shutting down. The purpose of this is to reduce the impact on the speaker when starting and shutting down.
It is forbidden to unplug or plug in the signal plug with electricity. In order to avoid damage to the machine or speaker due to the electric shock; in case of any abnormality during the operation of the machine, turn off the power immediately and stop using; if the operator does not know the maintenance technology, do not turn on the machine without permission, so as to avoid greater damage to the machine or electric shock accident.
4、 Pay attention to the maintenance of the machine
Do not use volatile solution to clean the machine, such as gasoline, alcohol, etc. to wipe the surface of the machine, and use a soft cloth to wipe the dust. And unplug the power supply before cleaning the machine shell. Generally, the machine is not waterproof. In case of wet water, the machine can only be started after the water is dry. Do not place heavy objects on the machine to avoid deformation of the machine.
In our life, we will get a variety of relatively large security issues from various aspects. As long as we pay attention to the elimination of security risks in the process of use, public broadcasting will play a greater practical value. Because there is no small matter about security, ensuring national security is an important prerequisite for doing everything well.
