to attach the BP-L60(A)/L90(A).
For details, refer to "To attach
the battery pack" on page 2-1.

instructions of the DC-210.
You can also connect another battery
pack to the DC IN connector when a

mounted on the top panel of this unit.
When you connect an external battery
pack to the DC IN connector, the
power supply automatically switches
to the external battery pack from an
internal battery pack mounted on the
top panel of the unit.
Notes
• Noise may occur in video and audio
signals at the moment when the unit
switches from the internal to the
external battery.
• It is always the external batteries
connected to the DC IN connectors
that serve as power supply. You
cannot switch the power supply from
the external batteries to the internal
batteries while the external batteries
are connected to the DC IN
connector.
When an external battery pack is
almost exhausted
If an internal battery pack is already
mounted, disconnect the external
battery pack by pulling its DC power
cord out from the DC IN connector. If
no internal battery back is mounted,
disconnect the external battery pack
after mounting a fully charged internal
battery pack.
When an internal battery pack is
almost exhausted
Connect a fully charged external
battery pack to the DC IN connector,
then exchange the internal battery
pack.
