or www.zircon.com.

2. INSTALLING THE BATTERY

Lift tab on bottom end of clip to release end cap.
Slide 9 Vcc battery into compartment, terminal side  

first, matching (+) and (-) terminals from battery 

to case.
Slide the clip onto  

the receiver, pressing  

down on battery  

until both pieces  

snap together.

3. LOCATING A CIRCUIT
Note: A small percentage of circuit boxes are mounted  

with breakers oriented vertically. See diagrams for  

proper receiver orientation.
Warning: For indoor use only on standard  

110–120 Vca outlets.

Plug the transmitter into the outlet that needs to be turned off.
Verify that the red LED glows, indicating a live circuit.
Go to the circuit panel. Turn on the receiver 

and hold it against the breaker as shown. 

5. HELPFUL HINTS

It is important to hold the receiver at an angle so that the entire 

CONTACT AREA of the receiver touches each circuit breaker.

Slowly scan the receiver over all breakers. This calibrates the unit. 

During this first pass while the unit is calibrating, the receiver 

may indicate more than one breaker. This is normal. If you have 

more than one panel, be sure to perform this step on each panel. 

Do not turn off the receiver.

Perform a second pass over the breakers. 

When the green 

LED glows and the buzzer sounds, you are directly over the 

breaker connected to the transmitter.

Turn off the breaker.
Verify that the red LED on the transmitter is off, indicating a dead 

circuit, before beginning work.

4. CLEANING AND STORING THE UNIT

Clean transmitter with dry cloth only. Do not expose product  

to liquids. 
Snap the transmitter and receiver together for storage.

Situation

Probable Causes

Solutions

No indication, i.e., no 

green LED and buzzer.

Multiple indications on 

second scan.

Tracing circuit connected 

to light fixture.

Receiver indicates 

breaker above the  

correct one.

The breaker for that circuit is 

not in the box being scanned.

The first scan was performed 

too quickly.

Receiver is held horizontally 

with only the tip of the receiver 

contacting the breaker and 

not an angle (see illustration 

in Step 3).

Scan the box that supplies  

that circuit.

Scan again, moving the receiver 

slowly. Be sure to keep the nose of 

the receiver close to the breaker 

and maintain proper orientation.

Use an outlet adapter. Screw the 

adapter into the socket, then plug 

the transmitter into it. Or plug an 

extension cord into the adapter, 

then plug the transmitter into the 

extension cord.

Hold the receiver at an angle so  

the entire CONTACT AREA of 

the receiver touches each circuit 

breaker (see illustration in Step 3).
