Do not use TENS:
- If you have a heart pacemaker or have a heart rhythm problem. TENS in the direct vicinity of a pacemaker may affect some models. If TENS is applied on the front of the neck, this can affect your heart rate. Very strong TENS across the chest may cause an extra heartbeat.

- During the first three months of pregnancy. It is not known whether TENS may affect foetal development.
- On the abdomen in the later stages of pregnancy. Stop use immediately if you experience unexpected contractions.
- When driving, operating machinery or similar actions needing fine control. Loose pads, damaged leads or sudden changes in contact may cause brief involuntary muscle movements.
- To mask or relieve undiagnosed pain. TENS may delay diagnosis or progressive condition.
Caution:
