NOTES:
1) The maintenance and replacement intervals for the CD/DVD library are variable depending on the operating conditions such as the
number of additional optional drives and the frequency of use. It is recommended to replace each drive after every 30,000 disc
loading cycles. To check the operation of the CD/DVD drive, perform recording and playback of the exclusively designed CD/DVD
disc.
2) The service life of the CD/DVD drive is variable depending on the write count (the total time spent in the write mode).
3) Each disc carrier tray should be replaced after every operation count of 10,000 cycles.
An operation refers to each operation cycle of the carrier. When the carrier has pulled out a magazine tray, inserted a disc in it and
then returned it to its original magazine, the operation count becomes 2.
4) When an MC-CF10 optional carrier is used, it is recommended that it should be replaced after 300,000 inversion operations.
The inversion count can be checked as describe in section "11. Access Count" of the instruction manual.
