The Olympus A-514 AC Adapter is made for use with the Olympus DM901 and Olympus DM620 model digital voice recorders. Connect your USB cable on one end to the recorder and the other end to the A514.
This ac adapter does have the usual inputs it connects to the usb on the dictation recorder. This is very unusual. The dictation recorder needs to be switched manually into the power supply mode on the recorder. You must do this for the recorder to receive power.
Included in the pack is adapters for the U.S., U.K., Australia and Japan.
