This function is used to add new sound on the STEREO2 track of previously recorded tape.

See pages 24-33.
Operations
Press EDIT MENU.
On Screen Display
Select Program Editing, and then
Press OK.
Notes:
Program Editing can be performed using either the tape
counter or Time code display.
If you attempt to switch to the tape counter display in order
to perform editing after setting the editing points using the
Time code display, the Erase all programs screen is
displayed.
(The Erase all programs screen is also displayed when you
change from the tape counter display to the Time code
display.)
Program editing can not be performed with a movie camera
that has a 4-digit counter.
After setting a program, if you attempt to set another
program in a different editing mode, the set contents for the
previous editing mode remain on the setting screen. In
order to prevent editing errors, perform the Erase all
programs operation (page 61) whenever you set a program
under a different editing mode.
Audio Dubbing is not possible in the following cases:
When the tape in the recording VCR (this unit) is:
Recorded in 16bit audio mode;
Recorded in LP mode;
Blank, or contains a blank portion in the middle
When INPUT SELECT is set to DV IN.
