That might have not been necessary. I think these units have an internal battery. If you don't use the receiver for an extended time (if it is unplugged from USB), then eventually the battery will discharge itself. The next time you use the GPS receiver, the unit should go into factory settings. I'm not sure about BU-353, but batteries in some other receivers may take even a couple of weeks to discharge :-)
