Remarks
Confirmation of pickup laser power
It is possible to confirm in the record/playback mode with the aid of laser power meter. However, since the laser power meter
measurement is characterized with dispersion, obtained data are used only for confirmation.
Reference data (at room temperature 25°C)
Playback: 0.72±0.1 mW
Record: 5.5±0.5 mW
Note: Never see directly the laser light. Otherwise your eyes are injured.
With the pre-adjustment disc (MMD-318)
If "R/P WHICH?" appears, the mechanism and the PWB can be mismatched. Check whether the combination of the playing/
recording PWB and mechanism are appropriate.
If "R/P WHICH?" still appears, eject the disc and check as follows.
Check 1: Check the pin 100 line of IC1401 for defective soldering. Check the pin 93 line of IC1401 for short-circuit and defective
soldering (Also check the SW PWB).
Check 2: Check the pin 3 line of IC1401 for defective soldering and short-circuit with other patterns. Check that the pickup laser
is not broken.
