To ensure reliable functionality, we test the devices with special test CDs. Using the so-called "eye pattern", which is measured with an oscilloscope, we can determine how well the laser reads the information on the CD. We use this data to decide, among other things, whether devices are still suitable for sale. whether the laser unit needs to be replaced. 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.
