To ensure a reliable function, we test the devices with special test CDs. Via the so -called "Eye Pattern", which is measured with an oscilloscope, we can determine how well the laser reads the information of the CD. Based on this data, we decide, among other things, whether devices are still suitable for sale or whether the laser unit must be renewed. The electronics of the electrical devices are examined closely. Thanks to many years of experience, we can Fix type-specific vulnerabilities before an error occurs. The lifespan of certain devices can be increased enormously. The devices are presentable . There may be a few small blemishes on the front and/or a few small paint scratches (no longer than approx. 5cm) must be present. From approx. At a distance of 2 meters, these traces are.
