OPERATING INSTRUCTIONS
1. Identify the wall outlet or fixture for which the breaker must
be determined.
2. Safely check that the outlet or fixture is live.
3. Plug in the transmitter. Its LED will light if it is receiving power.

5. Turn on the receiver by pressing, but not holding, the power button.
You will hear a beep and see its LED lit.
6. Position the receiver perpendicularly on the breakers in the panel
with the power button pointing up.
7. Slowly scan all breakers in the panel once. Ignore any beeps
or indications, as the receiver is learning the panel.

and illuminate the green arrow only at the correct breaker.
9. Power off the receiver by pressing and holding the power button.
Return to the outlet or fixture and remove the transmitter.
