1 Turn the POWER switch of the DVW-250/250P off.

2 Connect the DC IN 12V connector of the DVW- 250/250P to an AC supply through the AC-550/ 550CE AC Adaptor, as shown in the figure.

3 Set the EXT DC SELECT switch according to the way in which you wish to use the AC supply. AUTO: If the voltage of the AC supply drops, the

unit switches automatically to the internal battery pack.

FIX: Only the external power supply is used.

4 Turn the POWER switch of the AC adaptor on.

Note

While an AC power supply is connected, then regardless of the state of the POWER switch on the DVW-250/250P the time code circuits continue to operate, consuming some power. If not using the unit for a considerable time, disconnect the power cord between the DVW-250/250P and the AC-550/550CE.
