After charging the battery pack
Disconnect the AC power adaptor from the DC
IN jack on your camcorder.
Note
Prevent metallic objects from coming into contact
with the metal parts of the DC plug of the AC
power adaptor. This may cause a short-circuit,
damaging the AC power adaptor.
Remaining battery time indicator
The remaining battery time indicator in the
display window indicates the approximate
recording time with the viewfinder.
Until your camcorder calculates the actual
remaining battery time
"---- min" appears in the display window.

any trouble occurs with this unit, disconnect the
plug from a wall socket as soon as possible to cut
off the power.
