Laser lens maintenance
If the CD player fails to read CDs correctly, you can clean the laser lens.
This operation must be performed with extreme care.
First, blow some air onto the lens to remove any particles that could scratch the
lens's anti-reflectivity layer.
Cleaning must be performed using a non-abrasive cleaning liquid. We advise
using a photographic lens cleaning product or for glasses.
Clean the lens with a lightly impregnated cotton bud. Exert only a very small
amount of pressure and imperatively follow the movement shown below.
WARNING: Any other cleaning method could destroy the lens.
