I river H120
idle shutdown was on but im 100% sure it was recording cause ive got the files...
the only thing i think it could be is heat protection... cause the player was fully hott i had in a hot area...
the battery was 100% charged and continued to record for a 2nd time and then turnd off again.. 3rd and 4th time in a different location it was fine...
the keypad lock was turned on..
i did a rec test today with the new firmware installed fully charged battery 320kbs mp3 8hrs 23mins - 1.12gb n the battery fully died
