1. Install a fresh 9-volt battery in the reciever. ( Battery not included)

2. Plug the transmitter into the live wall outlet. (see #1a) or the HTP-SA light socket adapter.(sold seperately) on the circuit you wish to identify. The LED will glow indicating power.

3. Turn the reciever power on by rotating the rotary power switch back until it clicks (see #2). The reciever will beep and the LED light above the switch will illuminate

4. At the breaker box, hold the reciever perpendicular to the breakers with the power switch facing upwards, scan the rows of breakers in a slow up and down motion (see #3). During the scan the reciever will beep when passing over several breakers. After the Initial scan of all the breakers adjust the rotary switch back 1/4". Repeat this process of scanning the breakers and adjusting the rotary switch until only one breaker causes the reciever to beep. When this happens, congratulations, you have found the correct breaker! If during the scanning process none of the breakers activate the reciever, simply adjust the roatry switch by moving it forward 1/8" and rescan the breakers.

5.When you have finished be sure to turn the reciever off by, rotating the roatry power switch forward until the switch clicks and the LED above the switch turns off. Always be sure to unplug the transmitter when finished.
