Mis-features: No date/time stamp during recording. Be aware that when recording from the mic input and you adjust the recording level, a small 'glitch' (a few millisecs silence) will be recorded where the level drops from MIC 'H' to MIC 'L' (position 20 on the 0 - 30 level scale). -Graham Baker

TOC Undo: TOC Undo with the Kenwood DMC-J7R is very simple: Remove the battery/unplug the power supply without turning the unit off. When powered up again, it forgets that there are unwritten TOC changes. -Stefan Werner

Problems: There have been reports on MD-L of Sharp MD-MS701/702 units malfunctioning, displaying intermittent "UTOC Error" messages with damaged/irrecoverable recordings as a result. A user ([email protected]) advises:

1. It is important not to do an auto calibration in service mode without a "tdys1" (sony) testing MD or equivalent (Teac). This will definetly cause more problems!
2. Unit should be returned immediately when the first UTOC errors appear, it is a bad sign! It makes no sense to wait until the warranty has expired.

Accessories: Sharp seems to have sold the MD-MS702 outside of Japan without the external AA cell case. It's available though from Planet Minidisc and Minidisco.
