Used once on one cable. Went to use again, and the screen lights up but is blank or the 4 and 8 come on and blink. Changed batteries and same. What can be done to fix this issue? This is my first experience with Southwire and so far not a good one.

I need to trace a data cable from a PC back to a LAN switch. When connecting the M400TP @ PC patch cable, w/ switch end connected to switch, should the warble be silenced when connected? Using a wand, as soon as patch cable is unplugged, warble returns.

Asked by: Pat61
When the signal stops being generated, is the cable connected into the switch? I would try removing that from the switch end and try picking the signal up again. If the cable is plugged into the switch while sending a tone that may nullify the tone.
