CLEAN THE LENS CD DRIVE LENS CLEANING Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “KODAK LENS CLEANER CAT 176

It is advised to clean the lens gently (dont press too hard) with a soft and clean cotton bud moistened with the special lens cleaner. The dire

MEASURE THE EYE-PATTERN SIGNAL EYE-PATTERN SIGNAL JITTER MEASUREMENT Measure the signal direct on resistor 3898 using an oscil- loscope (see also chapter 10-9). See below examples of the signal. Amplitude should read at least

MEASURE THE LASER CURRENT CD DRIVE LASER CURRENT MEASUREMENT The laser current can be measured as a voltage drop on resistor 3820.Typical value 170 - 190mV for CD-DA res- pectively 200 - 220mV for CD-RW. 5. MEASURE THE OFFSET

11、S OF THE CD-DRIVE CD DRIVE OFFSET MEASUREMENT Each photodiode of the CD-drive may have an offset. This offset has to be compensated by the signal proces- sor. A high offset of the CD-drive leads to poor playability of some CDs (skipping tracks). Start the Service Test Program - section Focus Test“ w
