To ensure reliable function, 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. Based on this data, we decide, among other things, whether devices are still suitable for sale or not. whether the laser unit needs to be replaced. The electronics of the electrical devices are examined closely. Through many years of experience we can provide specific or Fix type-specific vulnerabilities before they cause an error. For certain devices, the service life can be increased enormously. The devices are presentable . There may be isolated small blemishes on the front and/or isolated small paint scratches (no longer than approx. 5cm) must be present. From approx. A.
