Before Starting: It is very important to shave any visible hair before use. Ensure your skin is completely clean and dry (don’t use any gels or creams with your handset).  Instructions: 1) Plug the handset in and click the green button on the back to turn it on.2) The green button is also used to switch through the intensity levels  (1 for low - 5 for high). The blue lights on the front will indicate the intensity level. 3) Make sure your intensity level is set to 1 if it is your first session. For the best results, you should use your handset on the highest possible intensity level that isn’t painful. We recommend gradually increasing the intensity level after each session if the experience was not painful. 4) To use, ensure that the light window is completely flat against the skin. The pink light will begin to blink once you’ve placed the light window onto your skin. This indicates that the handset is ready to be used. The handset has a sensor and will not flash unless the light window is in direct contact with your skin. If it is not in direct contact with your skin, the pink light will stay illuminated and the handset will not flash. 5) Click the Pulse button. Continue this over multiple areas until finished. Lift the head slightly after each pulse to avoid overheating. For stubborn areas, we recommend that you treat the area up to 2 times per week and to try a higher intensity. 6) Press and hold the green button on the back to turn it off. Always disconnect device from the electricity supply when finished.
