In our daily lives, we often enjoy the convenience brought by public broadcasting. There are many new information that we will obtain through public broadcasting in the first time, and this will contain many opportunities. But while we enjoy the benefits that public broadcasting brings us, we should also pay attention to the safety precautions when using public broadcasting:

1、 Pay attention to the usage conditions of the machine

Special attention should be paid to the following: avoid using the machine in environments with extremely low or high temperatures, and avoid direct sunlight on the surface of the machine; Avoid using the machine in a damp environment to prevent premature failure of internal components or premature rusting of the machine; Before use, it is necessary to confirm that the local power supply voltage matches the machine.

2、 Pay attention to the operating environment of the machine

Avoid using the machine in dusty and vibrating environments; There should be sufficient clearance around the machine to facilitate heat dissipation; For power amplifiers, special attention should be paid to keeping the heat dissipation channels unobstructed.

3、 Precautions for machine use

During use, attention should be paid to the order of power on and off. When starting up, the audio source and other front-end devices should be turned on first, and then the power amplifier should be turned on; When shutting down, the power amplifier should be turned off first, and then the pre equipment such as the audio source should be turned off. If the audio equipment has a volume knob, it is better to turn the volume knob to a lower position before turning it on or off. The purpose of doing this is to reduce the impact on the speaker during startup and shutdown.

It is strictly prohibited to unplug or plug in signal plugs with power on. To prevent damage to the machine or speaker caused by the electrical shock generated thereby; If any abnormalities occur during the operation of the machine, the power should be immediately turned off and the use should be stopped; If the operator does not understand maintenance techniques, they should not open the machine without authorization to avoid causing greater damage to the machine or causing electric shock accidents.

4、 Pay attention to the maintenance of the machine

Do not use volatile solutions to clean the machine, such as wiping the surface with gasoline, alcohol, etc. Use a soft cloth to remove dust. And when cleaning the machine casing, you need to unplug the power first. Machines are generally not waterproof. In case they get wet, they need to wait for the water to dry completely before starting up and working; Do not place heavy objects on the machine to avoid deformation.

In our lives, we will obtain various significant safety issues from various sources. As long as we pay attention to the elimination of safety hazards during use, we can make public broadcasting play its greater practical value. Because safety is no small matter, ensuring national security is an important prerequisite for doing everything well.
