How to access service mode on the Sony MDS-JB930 MiniDisc deck. The JB930 has several built-in odometers allowing the user to access the deck's total record and play times. The record time is how long the recording head has been in "write" mode (or how long the laser was set to the high power state), not the actual disc recording time (which is approximately four times the number displayed).
