| 1、What is an unswitched outlet? |
|
| An unswitched outlet is designated outlet, which is not controlled by the main on/off switch. It provides power to products that need continuous power, such as clocks and desk lamps. |
| 2、What does the grounded light tell me? |
|
| This LED will let you know that the outlet you are plugging the surge protector into is properly grounded. If not properly grounded, a surge protector will not be able to protect the equipment and the warranty is voided. |
| 3、What does EMI/RFI mean and is it important? |
|
| Electromagnetic Interference (EMI) is defined as electrical magnetic noise usually caused by microwaves, elevators, and air conditioner. Radio Frequency Interference (RFI) is a specific type of EMI within the frequencies of 60 KHz to 200 MHz. This interference can scramble your sensitive data and cause damage to the hard drive. |
| 4、Is it important to protect a telephone line? |
|
| Yes, phone/fax/modem protection is very important is very important. Electrical surges can enter your home or office through the telephone lines to harm and even destroy sensitive electronics, including your computer. Using a surge protector with telephone protection is the only way to properly protect your telephone, fax, and modem devices. |
| 5、What are surge and spike? |
|
| A short-term increase in voltage (average 500 volts), typically lasting at least 1/120 of one to two seconds. |
| 6、Why would I need an audio/video surge protector? |
|
| Electrical surges can also enter your home or office through the coaxial cable lines. A surge protector with coaxial cable protection is the only way to properly protect your audio and video equipment. |
| 7、What does UL 1449 rating of 330V mean? |
|
| UL is an independent, nonprofit, product safety testing and certification organization that inspects the safety and quality of surge protectors on the market. UL 1449rating of 330V is the UL’s highest rating. |
| 8、Why do you need surge protectors? |
|
| Even small surges or spikes can eventually destroy or affect the performance of expensive electronic equipment such as a computer, telephone, fax, TV, audio/video equipment, and other household electronics and appliances. Damage can occur either instantaneously or over time as smaller surges cause the gradual deterioration of internal circuitry. The common use of microprocessors (computer chips) has increased the need for surge protection because these chips are generally very sensitive to voltage fluctuations. |
| 9、How do the surge protectors work? |
|
| Surge protectors act like an electrical sponge, absorbing dangerous excess voltage and preventing most of it from reaching your sensitive equipment. Like a sponge, surge protectors have a limited capacity to absorb. Once the capacity is reached, the unit is no longer protecting your equipment and it should be replaced. |
