To use the AC-550/550CE
As shown in the following figure, connect the AC-550/550CE to the AC
power source and turn it on.
When you connect AC power, the power supply automatically switches to
the AC power from a battery pack mounted on the top panel of the unit.
Note
Noise may occur in video and audio signals at the moment when the unit
switches from the battery pack to AC power.
To use the AC-DN2A/DN2B
Follow the procedure below to mount the AC-DN2A/DN2B on the top
panel of this unit, and connect to AC power.
When two DSR-70A/70AP units are combined, you can supply both units
with power by fitting a single AC-DN2A/DN2B to either unit.
Caution
When you use a single AC-DN2A/DN2B to supply power to two DSR-
70A/70AP units, exercise the following caution:
• Do not turn the POWER switches of both units on at a time. (Turn one
unit on, then wait a moment before turning the other unit on.)
• Do not insert cassettes into both units at a time. (Insert a cassette into one
unit, then wait a moment before inserting a cassette into the other unit.)
If you turn on the POWER switches of the recorder and player at a time or
insert cassettes to the recorder and player at a time, this unit possibly may
not be powered. In this case, turn the POWER switches of both units off,
then turn them on again following the above instructions. Should this unit
not be powered, turn both POWER switches off and disconnect the AC
power cord of the AC-DN2A/DN2B. After about 10 minutes, connect the
AC power cord of the AC-DN2A/DN2B again and turn the two units’
POWER switches on one by one as mentioned above.
