选购标签注意事项：

在选购标签后，好多客户发现好多问题，不报警、胶贴不了，会复活，不解码等等问题。这些问题下面我为您做一个解答：

一、在RF-EAS的领域上国际惯用8.2MHz为中心频率段。但这个频率的主机主板有R4调解频率的宽限，通常为8.1-8.5MHz之间，所以在超出8.1-8.5MHz的频率范围外，主板的接收信号就会减弱，通常叫灵敏度，所以不报警是在这个频率外的标签。

二、由于区域的温差非常大，热容胶不干胶是在常温下才有胶性，通溶点在10℃到20℃为最佳温度，低于10℃热溶胶就会开始固化，高于20℃就会溶解，所以过高或过低的温度都会倒至粘不了。

三、会复活，由于很多生产商为撑握不了CTR工艺，也就没有开发CTR工艺，保证不了解码，所以解码后会复活或不解码标签。严重导至超市与超市客户之间的严重的误会。

Notice in choosing and buying labels：

Some client find a good deal of questions after choosing and buying labels, like don’t give an alarm, can’t be stick, relive, can’t be decode and so on. I can answer the questions for you:

Ⅰ.In the field of RF-EAS, the frequency of 8.2MHz is consistently use. But the frequency of mainframe has a extend a time limit of R4, always between 8.1-8.5MHz. As a result, the signal of mainboard will be weaken, we always call that degree of sensitive. Don’t give an alarm is because it’s out of the frequency.

Ⅱ. Because of difference in temperature, the mucus always has the nature of mucus under normal temperature, the best temperature of it is between 10℃to 20℃, it will solidify when the temperature below 10℃while it will dissolve when higher than 20℃, so it can’t be in too high or to low temperature.

Ⅲ. Relive, in reason of many manufacturers can’t learn the technics of CTR and didn’t empolder the technics of CTR, this manufacturers can’t ensure decode, so the label maybe relive or can’t be decoder, and lead the misunderstand between customer and supermarket.
