Operation
WARNING: Always test on a known good circuit before
use.
WARNING: Refer all indicated problems to a qualified
electrician.
Locating a Circuit Breaker or Fuse
The transmitter injects a signal onto the circuit which can be
detected by the receiver. The receiver will beep when the
signal is detected. The sensitivity adjustment allows for tracing
and pinpointing the exact circuit breaker or fuse protecting the
selected circuit.

1.
Plug the Transmitter / Receptacle Tester into a powered
outlet. The two green LED's should illuminate.
2.
Rotate the Receiver's Sensitivity adjustment from the
OFF position to the HI position. The red LED should turn
on. If the LED does not turn on, replace the battery.
3.
Test the operation of the Receiver by placing it in close
proximity to the transmitter. The receiver should beep
and the LED should flash.
4.
At the breaker panel, set the sensitivity to the HI position
and hold the receiver as indicated by the "UP - DOWN"
label.
5.
Move the receiver along the row of breakers until the
selected circuit is identified by the beep and flashing light.
6.
Reduce the sensitivity as needed to pinpoint the exact
circuit breaker controlling the circuit.

The three LED's will indicate circuit condition. The
diagram lists all of the conditions that the CB10 can
detect. The LED's in this diagram repr&sent the view
from the GFCI button side of the transmitter. When
viewing the other side of the transmitter the LED's will be
a mirror image of those shown here.

The tester will not indicate the quality of the ground
connection, 2 hot wires in a circuit, a combination of
defects, or reversal of ground and neutral conductors.
Receptacle GFCI Test
1.
Before using the tester, press the TEST button on the
installed GFCI receptacle, the GFCI should trip. If it does
not trip, do not use the circuit and call a qualified
electrician. If it does trip, press the RESET button on the
receptacle.
2.
Plug the Transmitter / Receptacle tester into the outlet.
Verify that the wiring is correct as described above.
3.
Press and hold the test button on the tester for at least 8
seconds, the indicator lights on the tester will shut off
when the GFCI trips.
4.
If the circuit does not trip, either the GFCI is operable but
the wiring is incorrect, or the wiring is correct and the
GFCI is inoperable.
Replacing the Battery
1. When the battery drops below the operating voltage the
receiver's LED will not light. The battery should be
replaced
2. Remove receiver battery cover by removing the screw
using a Philips head screwdriver. (The Transmitter is line
