Confirm the device-side plug and the pad-side connection before purchasing.\u003c\/p\u003e\u003ch3\u003eDoes 2mm refer to the device plug or the electrode pad connector?\u003c\/h3\u003e\u003cp\u003eOn this product, 2mm refers to the pin connection at the electrode pad end. You must check the device-side plug separately against your original cable and device manual.\u003c\/p\u003e\u003ch3\u003eCan these TENS cables connect directly to snap electrode pads?\u003c\/h3\u003e\u003cp\u003eNo. These lead wires use 2mm pins at the pad end, not snap connectors. Choose pads with a matching 2mm pin connection, or use the lead wire type specified for your snap pads and device.\u003c\/p\u003e\u003ch3\u003eHow do I know whether the wire or pad is causing a problem?\u003c\/h3\u003e\u003cp\u003eWith the unit switched off, inspect both components and reconnect them. Test with a known-good compatible pad and cable one component at a time, restarting at the lowest intensity after every change.\u003c\/p\u003e\u003ch3\u003eCan I test the wire while the TENS unit is running?\u003c\/h3\u003e\u003cp\u003eDo not pull, bend or reconnect cables while stimulation is active. Switch the unit off and return intensity to zero before making any connection change.\u003c\/p\u003e\u003ch3\u003eDo two cables support dual-channel use?\u003c\/h3\u003e\u003cp\u003eYes, when the TENS unit has two compatible output channels and each cable matches the device and pads. Adjust each channel separately according to the manual.\u003c\/p\u003e\u003ch3\u003eDo I need new electrode pads too?\u003c\/h3\u003e\u003cp\u003eNot necessarily.
