Troubleshooting chart (continued)
Cause
The unit has failed in loading or saving
the cassette memory data.
An incorrect type of cassette is loaded.
At the recording, the ClipLink function is
set to on (meaning ClipLink shooting is
allowed) in menu 211, CONT is displayed
in the display window and the time code
generator is in the REGEN mode.
Remedy
Load a new cassette (page 59).
Load a correct type of cassette (page
59).
Only the REGEN mode can be used for
ClipLink shooting. If you will not perform
ClipLink shooting, set the ClipLink
function to oFF (see page 123).
