Locating A Circuit Breaker or Fuse:
1. Plug the transmitter into the receptacle.    
2. Go to the circuit breaker panel box.  
3. Turn the receiver on. 
4. Place the flat surface of the tapered end of the receiver directly onto the circuit breaker or fuse as shown.
   If the receiver is held at any other angle, inaccurate readings may occur.
5.  Slide the nose of the receiver down each breaker along both sides of the panel. Note
  that the receiver will beep frequently as it measures the relative signal strength.
6.  Move the receiver down each breaker once more.  On the second pass, the receiver
  will beep and the red LED will light only at the circuit breaker powering
  the transmitter.   
7.  Trip the breaker off and check that the LED on the transmitter in the outlet is off
  to confirm you have found the correct breaker or fuse.
Locating a Circuit Breaker or Fuse Controlling an Incandescent Light Fixture
1. If the incandescent light fixture is controlled by a wall switch, make sure the wall switch is OFF.
2. Remove light bulb.
3. Install a Screw-in socket adapter (not included).
4. Plug the transmitter into the adapter.
5. Turn on the wall switch and follow the procedure described in Locating a Circuit Breaker or Fuse, steps 3 through 7.

定位断路器或熔断器：
1。将发射器插入插座。
2。转到断路器面板中。
3。打开接收机。
4。将接收器的锥形端的平坦表面，直接到如图所示的电路断路器或熔断器。
   如果接收器被保持在任何其他角度，可能会发生不准确的读数。
5。向下滑动鼻子的接收器每个断路器两侧的面板。注意
  接收器会发出蜂鸣声频繁，因为它测量的相对信号强度。
6。将接收下来每个断路器。在第二阶段，接收器
  会发出蜂鸣声，红色LED指示灯会亮起只有在断路器供电
  发射机。
7。断路器跳闸检查变送器在出口上的LED是关闭的
确认你已经找到了正确的断路器或熔断器。
查找断路器或熔断器控制白炽灯灯具
1。如果白炽灯灯具，墙壁开关控制，确保墙壁开关处于关闭状态。
2。取下灯泡。
3。安装螺丝插座适配器（不含税）。
4。将发射器插入适配器。
5。打开墙壁上的开关，并按照定位断路器或熔断器描述的过程，步骤3到7。
