The HighWave can be worn on the left or right wrist; It will have the same effect regardless of where it is worn, as long as there is good contact with the skin. Both metal contact pads need to touch the skin directly to generate the electrical field for the high-frequency carrier wave to be distributed to the body. It will have the same effect whether the skin is dry or wet, but if you have particularly dry skin, you can add water if needed.

The HighWave requires that the Healy be used in high current mode to work. If you prefer to use your Healy in low current, you can switch to high current when using High Wave, then switch back to low current after. Although some users may feel the electrical field, most will not.
