Inserting and Replacing the Lithium Battery
The camcorder uses a lithium battery to retain stored
data. When using the camcorder for the first time, be
sure to insert the supplied lithium battery (CR2032).
The camcorder will not operate correctly without this
lithium battery.
Lifetime of the lithium battery
When the lithium battery's voltage falls, the lithium
backup battery warning appears in the display
Li
window. If this warning appears, replace the lithium
battery (CR2032) within three or four days.
The lithium battery has an average service life of about
two years, however operation in ClipLink mode will
shorten the lifetime until about one year (when the
DSBK-301 is fitted).
