TC generator setting

When the optional TC/SYNC card is installed, this item selects the time code recording
mode. When the optional TC/SYNC card is not installed, this item selects the recording
mode of LTC which is always recorded simultaneously with audio signals.
When the optional TC/SYNC card is not installed, by selecting "
[ENTER/YES] key, you can select a desired LTC recording mode between "REC R" and
"EXT" (the default is "REC R"). See the table below for details of these modes. You can
also select the TC generator setting via the "Gen mode" menu item in the "TC SETUP"
menu of the MENU mode (see page 80 and 128 respectively).
The first time you start recording, the generator stamps "01h00m00s00f" as the
REC R
LTC start time at the beginning of the file, and records LTC jammed to this start
(Rec Run)
time code. The next time you start recording, LTC continued from the LTC on the
previous file is recorded.
Every time you start recording, the generator stamps "01h00m00s00f" as the LTC
EXT
start time at the beginning of the file, and records LTC jammed to this start time
(Ext Run)
code. In other words, every file has LTC which starts from "01h00m00s00f".
