Using this adapter will provide you with the optimal acoustic sound andfunctionality. It behaves like a soundcard controller that once connectedto your computer or laptop, works with all your apps that use audio,maximizing your audio experience.How do I connect my Voyager Focus 2 to the BT700 Bluetooth USB Adapter? Typically, your BT700 USB adapter is pre-paired (connected) to your headset. If it does not automatically connect when plugged in then it has somehow disconnected, or it was purchased separately. You will need to connect /pair the adapter to your headset. For this you will need to download the Poly Lens app at /lensa. Insert the Bluetooth (BT) USB adapter into your laptop orcomputer and wait for your computer to recognize it.b. Put your headset in pair mode (On the headset, slide and holdthe Power switch away from the off position until you hear“pairing” and the headset LEDs flash red and blue).c. Put your Bluetooth USB adapter into pair mode using PolyLens: Click on the three blue dots in the bottom right corner- select "Pair Device". Your BT700 adapter flashes red andblue.d. Pairing is successful when you hear through theheadset "pairing successful" and "PC connected" and theBluetooth USB adapter LED is solid.Am I able to use my BT700 USB Adapter on multiple devices?LEARN MY DEVICE Your BT700 Bluetooth (BT) USB adapter will remember up to 2 devices but will only connect to one at a time. If experiencing trouble, check that your Voyager Focus 2 device is the only one connected, if required turn off the second device.What are the featuresavailable with my newVoyager Focus 2 andmy BT700?Call controls / volume Headset buttons can control call functions.

国家电线电缆标准 015-2019关于电线电缆线芯的允许长期工作温度，橡皮绝缘通常为65℃，聚氯乙烯绝缘为70℃，交联聚乙烯绝缘为90℃;短路时(最长持续时间不超过5s)导体的最高允许温度：聚氯乙烯绝缘为160℃，交联聚乙烯绝缘为250℃。

一、XLPE电缆与PVC电缆的区别：1.低压交联(XLPE)电缆自九十年代中期投入应用以来，发展迅速，目前已与聚氯乙烯(PVC)电缆各占市场一半份额。

交联电缆与聚氯乙烯电缆相比较，载流量较高，过载能力较强，使用寿命较长(PVC电缆环境较好时热寿命一般为20年，而XLPE电缆热寿命一般为40年);PVC燃烧时会分解释放大量黑烟和有毒气体，而XLPE燃烧时不会产生卤素有毒气体，交联电缆的优越性日益为设计和使用部门所认识。

电缆2.普通PVC电线电缆(绝缘和护套)燃烧时延燃迅速，助长火势，1～2min即丧失供电能力，其燃烧分解释放的黑烟可达伸手不见五指的程度，造成人员呼吸和疏散困难。

更为严重的是，PVC燃烧时会分解释放氯化氢(HCL)和二噁英等剧毒腐蚀性卤素气体，是火灾中致人死命的主要原因(占火灾死亡因素的80%)，并成稀盐酸导形电膜附着在电气设备上，严重降低设备的绝缘性能，形成难以清除的二次灾害。

二、阻燃电线电缆1.阻燃电线电缆应具有阻燃特性，根据《成束电线电缆燃烧试验方法》GB/T18380.3-2001，可分为A、B、C三种阻燃等级，A级阻燃性能最高。

美国标准和技术研究所对阻燃和非阻燃电线进行了对比燃烧试验，下列试验结果可以说明采用阻燃电线电缆的重要意义：a、阻燃电线比非阻燃电线可以提供15倍以上的逃生时间;b、阻燃电线烧掉的材料仅为非阻燃电线的1/2;c、阻燃电线的热释放率仅为非阻燃电线的1/4;d燃烧产生的毒气量仅为非阻燃产品的1/3;e、产烟性能，阻燃产品与非阻燃产品无明显区别。

2.无卤低烟电线电缆无卤低烟电线电缆应具有无卤、低烟及阻燃的性能，其指标为：GB/T17650.2-1999(无卤试验)GB/T17651.2-1998(低烟试验)PH加权电导率最小透光率PH≥4.3r≤10us/mmT≥60%3.耐火电缆a.耐火电缆的燃烧试验指标(供火温度和时间)，《电线电缆耐火特性试验方法》GB12666.6-90规定为：A级950～1000℃、90分钟;B 级750～800℃、90分钟。
