Procedure 1.Remove the top cabinet. 2.Put on a glove (thin type) to avoid touching the upper and lower drum with your bare hand. 3.Put a few drops of 90% Isopropyl alcohol on the head cleaning stick or on the chamois cloth and, by slightly pressing it against the head tip, turn the upper drum to the right and to the left. Notes: 1.The video head surface is made of very hard material, but since it is very thin, avoid cleaning it vertically. 2.Wait for the cleaned part to dry thoroughly before operating the unit. 3.Do not reuse a stained head cleaning stick or a stained chamois cloth.
