Operation
Testing the Transmitter and Receiver
1. Plug the transmitter into a powered AC outlet. The transmitter's LED will glow
indicating the transmitter is on.
2. Turn the receiver on by momentarily pushing the On/Off/Reset button. The red
LED will glow and the beeper will pulsate indicating the receiver is on. If not
functioning, replace the battery. (Refer to Battery Replacement in manual.)
3. Touch the scanning head to the face of the transmitter as shown in Figure 3.
The Green LED should turn on and the beeper should change to a continuous
tone indicating the transmitter and receiver are operating normally.

Locating a Circuit Breaker
WARNING:
Shock Hazard. Use extreme caution when working on live
circuits. Do not use transmitter on circuits that exceed 120V AC.
1. With the transmitter plugged into the powered AC outlet, go to the circuit
breaker panel. Open the door on the panel. Momentarily press the On/Off/Reset
button. See Figure 4. Touch the scanning head directly on the circuit breaker.
Move the receiver slowly down both sides of the panel passing over each
circuit breaker twice.
2. When the receiver detects the circuit breaker that is powering the outlet, the
red LED will turn off and the green LED will turn on. The beeper will change
to a continuous tone.

3. When the correct breaker is turned off, the green LED will turn off and the red
LED will turn on. The beeper will change from a continuous tone to a
pulsating beep.
4. Confirm that the power at the outlet is shut off. The LED on the transmitter
should be off. Double check the circuit before working on it by using a
voltage tester or meter.
Note: The receiver may detect more than one circuit breaker on the first pass.
On the second pass, the receiver will ignore false detections and identify a
single breaker. Do not press the On/Off/Reset button in between the first
and second pass.

Note:
• The On/Off/Reset button should be pressed momentarily every time a new
test is performed in order to reset the calibration.
• To conserve battery power, the receiver shuts off automatically after three
minutes.
• To turn the receiver off manually, press and hold the On/Off/Reset button for
at least one second.
• When the receiver battery gets low, the green light and beeper will turn on
and off repeatedly. Replace the battery immediately.
