Details Of The Osd Display In The Emg Display Mode - JVC HR-S5950EU Service Manual

1.3.3 Details of the OSD display in the EMG display mode

During the EMG display, the OSD shows the data on the deck
mode, etc. The details of the display contents are as follows.
Notes:
• The display is variable depending on the part No. of the
System Control microcomputer (IC3001) built into the
VCR. In the following, refer to the figure carrying the same
two characters as the top two characters of the part
number of your IC.
• The sensor information in the OSD display contents is par-
tially different from the mechanism sensor information in
EMG detail information <1>.
