what did a pioneer carpenter do in the pioneer time
how do you set your clock on a pioneer deh-1900mp car radio
The resposibilties that a pioneer farmer had to do was to milk the cows, set hens, make honey, and raise chickens.
I suspect you mean why do need to set the clock of the pioneer deh 1550? If this is the case the problem is that there is a wire that comes out of the radio that must have power all the time, that wire is for the memory. You also didn't state if the radio preset stations have to be reset also. This would also be an indication that the memory is not powered up when the key is off.
