Track Search F/R
The unit starts searching for the displayed track in the forward or reverse direction and will pause when it finds it.
Error Rate Count
An error rate is measured from the current Play/Pause position for about 10 seconds (duration of disc recording).
The result will be displayed on the FL display. Normally, search for the track to be measured then press the CUE key in
Pause mode. The error rate is displayed, for example, as "3.56E-4 OK." "OK" is displayed if the error rate is 3.00E-3 or less,
and "NG" is displayed if it is more than 3.00E-3. The result is determined on the assumption that the measurement is
performed using a control disc upon shipmentof the product. This measurement cannot be used for judging whether or not
the product is defective during servicing.

The loaded disc is ejected.
