Rewind the tape to the beginning to avoid
distortion of the picture or the sound. The
cassette should then be put in its case, and
stored in an upright position.
x When cleaning the gold-plated
connector
Generally, clean the gold-plated connector
on a cassette with a cotton-wool swab after
every 10 times it has been ejected.
If the gold-plated connector on the cassette
is dirty or dusty, the remaining tape
indicator may not show correctly.

sampling frequencies of audio and video are
synchronized. Therefore, lock mode is more

• This camcorder complies with the DVCAM
format. Though mini DV cassettes can be used
for recording, we recommend you use mini
DVCAM cassettes to get the most out of the
high reliability of the DVCAM format.
• The recording time of mini DV cassettes is 1/3
shorter than that indicated on mini DV cassettes
when recorded in the DVCAM format.
