Hello Maddeshi

There are two power inputs. Normally a red and a yellow.

The red is hooked to the IGN power. When you turn off the vehicle, radio turns off too.

The yellow should be connected to the battery (+12VDC) so it always has power. This is how it keeps the memory, the time.

It sounds like the are both hooked to IGN. Each time the vehicle is turned off, the memories are lost.

Your post says, "When I turn off the radio". If this happens with the vehicle still running, we have to dig a little deeper.

Hope this helps you,

Mike

I have a pioneer DEH 150 radio it's loses its memory when the isolator switch is turned off in the tractor?


The radio has been wired incorrectly so no 12v battery power is applied to retain memory when the isolator switch is turned off.

I am having KEH-P8900R/X1B/EW PIONEER, by default it is playing the radio station FM- AF, I am trying to change it AM, but I did not get sucess. Can you please advice, how to change it. Thanks &...


There should be a "band" button on the stereo. you may have to press it several times before you get to AM mode, depending on how many FM stations it will store in it's memory.

Can't set the radio stations


When you find a frequency that you
want to store in memory, press one of pre-
set tuning buttons 1through 6 and hold until the
preset number stops flashing.
The number you have pressed will flash in the
preset number indicator and then remain lit.
The selected radio station frequency has been
stored in memory.
The next time you press the same preset tun-
ing button the radio station frequency is re-
called from memory.

Memory of presets


You need to Check the Wiring Harness from the Stereo. There is a Constant Power Memory Wire (Should be Yellow or Orange). This needs to be Connected to the Cigarette Lighter Power Wire for Constant Power Memory. Please Rate My Response! Thanks!
