Frequently Asked Questions
What voltage sources can I safely connect the transmitter to?
It is not designed for energized circuits, and connecting above 52VDC may damage it.
How do I perform a basic self-test on the kit?
Set Tx switch to 'Tx', adjust probe sensitivity to MAX (+), power on the probe, and check for normal tone/adjustment performance near the transmitter cable.
What indicators show if a phone line is working?
Bright Green indicates a working line with correct polarity; no light means an open pair or no service.
How do I connect wires for standard tracing tasks?
Use the red alligator clip for one wire and the black alligator clip for equipment ground, or use modular connectors directly.
