2 Attach the DC-L90 to the top panel of this unit.
Use the same method that you use to attach the BP-L60(A)/L90(A).
For details, see “To attach the battery pack” on page 30.
To connect to the DC IN connector
Use the DC-210 Battery Adaptor.
For more information about connections, refer to the operating instructions of the
DC-210.
You can also connect another battery pack to the DC IN connector when a
BP-90(A) battery pack is already 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 battery connected to the DC IN connector that
serves as power supply. You cannot switch the power supply from the
external battery to the internal battery while the external battery is
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
For the remaining battery power indication (see page 66), the “BATT”
display flashes.
Connect a fully charged external battery pack to the DC IN connector, then
exchange the internal battery pack.
Using AC Power
You can operate the unit from an AC power source by using the AC-550/
550CE AC Adaptor or AC-DN2/DN2A (subsequently also refered to as
the AC-DN2(A)) AC Adaptor.
Use the AC-550/550CE to connect the AC power source to the DC IN
connector, and the AC-DN2(A) to connect the AC power source to the
battery connector.
