As cell phones make and take calls, they emit low-level radio-frequency (RF) radiation.

当手机拨打和接听电话时，它们会发出低水平的射频 (RF) 辐射。

RF technology is what most other wearable LED companies use too, like Xylobands, who do everything from Eurovision to corporate events.

大多数其他可穿戴式 LED 公司也在使用射频技术，比如 Xylobands，从欧洲歌唱大赛（Eurovision）到企业活动，他们的产品无所不有。

Let's start off with the simplest, RF wristbands, that receive a radio frequency communicating the precise timing and colors for each band.

让我们从最简单的射频腕带开始，它接收一个无线电频率，传达每个腕带的精确时间和颜色。

Stronger than FM radio signals, these RF waves are still a billionth the intensity of known carcinogenic radiation like X-rays.

这些射频波比FM无线电信号强，仍然是X射线等已知致癌辐射强度的十亿分之一。

We've got an RF warning on the camera, which means that the signal's not actually getting onto the tape. It's usually a head clog.

摄像机出现电磁射频的警告，就是说信号没法传入录像带。一般是磁头堵塞。

But the good news is that there are easy ways for those concerned about RF radiation to cut down on exposure.

但好消息是，对于那些担心射频辐射的人来说，有一些简单的方法可以减少暴露。

Using your cell phone's speaker or connecting a wired headset--- while keeping the handset away from your body--- drastically reduces RF exposure.

使用手机的扬声器或连接有线耳机——同时让听筒远离您的身体——可以大大减少 RF 暴露。

When fans went to their seats at Madison Square Garden, they found one of these RF wristbands waiting for them, each one pre-programmed to be a part of a different group.

当粉丝们来到麦迪逊广场花园的座位上时，他们发现座位上会有一个射频腕带在等着他们，每个腕带都被预先设定为不同组的一部分。
