3. Operating Instructions
3.1 Powering On/Off
To turn the shaver on, slide the power switch upwards. To turn it off, slide the switch downwards.
3.2 Shaving Technique
For optimal results, ensure the skin is clean and dry. Hold the shaver at a slight angle and move it against the direction of hair growth. Apply light pressure and use short, gentle strokes. The ultra-thin foil system is designed to follow facial and head contours for a close shave.
