If you only plug one wire, you should make sure that two pads connected with the same wire are placed on your skin at the same time so that the unit can work properly. If you plug two wires, you need to connect the 4 or 6 pads to the both wires and then place all of these pads on your skin at the same time, otherwise it will not work. 2. The TENS device will be shut off automatically because the timer is set for 10-60 minutes. The max timing for one running is 60 minutes. If you need more therapy for longer than 60 minutes, you need to reset it. Note: Not suitable for pregnant women and hypertension patients, and not safe for people with pacemakers.
