Error Message on Screen E 95:00
 

Hi all
The technician at our university has just acquired a couple of FS100s and when he records something a message of E 95:00 appears on the screen flashing on and off. He has follwed instructions in the manual of how to rid these kinds of messages, however it is not remedying the situation.
Anyone have any knowledge of this kind of thing? Reset button is doing nothing.
Thanks in advance
