<br> How to use audio equipment? this article here provides some useful recommendations for your reference: <br> 1. takes note of the conditions for the use of the machine: <br> General instruction of the machine are listed in the conditions .of use of the machine, such as: <br> 1. ambient temperature: -10 ¡ .æ-40 ¡ .æ-+ <br> 2. relative humidity: 50% -80% <br> 3. power voltage: 198V-242V <br> 4. frequency: 50Hz - 60Hz <br> Specifically, it is required: <br> 1 .. avoid temperature very low or very high environment machine, avoiding the direct rays of sunlight has the surface of the machine. <br> 2. avoid damp environment using the machine in order to avoid premature failure within components or machine premature rusting. <br .> 3. use the front must confirm the local supply voltage corresponds with the machine. <br> 2. takes note of the machine's use of the environment: <br> 1. avoid dust and vibration environment using the machine. <br> 2 .. in the machine's surroundings should leave enough empty space to facilitate heat dissipation of the machine. <br> 3. for power amplifier, should pay special attention to maintain cooling channel flow. <br> 3. the use of note: <br> .1. in the audio system, you should be aware of the power-on, shutdown sequence. Power-on, you should first open sources, open in front of the device, then; shutdown power amplifier, <br> You should close the .power amplifier, and then close the audio sources, and other leading devices. Audio equipment if the volume knob, power on, power off before the volume knob off to most <br> Small Office. The aim is to reduce the power on, power .off the impact of the speaker. <br> 2. pull the plug is charged, plug the signal. Avoid the resulting shocks and damage to machines or speakers. <br> 3. the machine to work if making an abnormal sound, immediately turn .off the power to stop using. And please experienced qualified maintenance personnel maintenance. Own <br> Not on the machine, so the machines suffer more damage or cause electric shock accident. <br> 4. takes note of the maintenance of the machine: .<br> 1. do not use volatile solvent-cleaning machines, such as gasoline, alcohol, etc, wipe the surface of the machine, dust with a soft cloth. But when the clean machine shell <br> To disable the power. < .br> 2. the machine is generally not waterproof, water in case of wet, wipe with a dry cloth, and water stains dry before startup work. <br> 3. do not place heavy objects on the machine to machine. <br> .5. safe use of the machine: <br> 1. never wet hands pulling, plug in the power plug to avoid electric shock. <br> 2. long term when not in use, move the power plug from the power supply. < .br> 3. do not let the iron pins, clips, coins and other metal conductive material falling into the tank, so as not to damage the machine. <br> 4. replace the fuse of the machine, you should strictly follow the requirements .change, is strictly prohibited the use of non-requirement of substitutes. <br> 5. machine in use, should be the case then place safety grounding. <br> 6. the machine is strictly prohibited in the case of overload or short- .circuit. <br> 7. a General in the civil power amplifier on the back panel has an auxiliary power outlet, not through its connection, hair dryer, iron, electric appliances, it can only be <br> Used to connect to the audio .device. <br> 8. at constant pressure power amplifier, its output will have a high output voltage and the output pin is generally longer, therefore in use, <br> It is important to ensure that the output pin of the safe and reliable .. <br> 6. Note the power line protection: <br> 1. to avoid the power cord is treading, was a heavy squeeze. <br> 2. do not pull the plug and brute force perverted, and power cords. < .br> 3. pull the plug from the socket, you should seize the plug and unplug it. <br> In short, modern audio equipment is a high-tech products, be sure to carefully maintained, safe use, and correct operation. For .beauty, and avoid unexpected losses..
