Check all the speakers connections for short circuits

unplug from wall
unplug all of the speakers and extra components and turn it on to see if the message disapears

if it does one by one start plugging that speakers back in
unplugging from the wall every time you add a speaker
(just in case the reciver only realises there is a problem after it shuts down)

if you find that after pluging in a speaker and when you turn it on check the wires for cuts or short circuits and check the speaker itself replace it with another and see what happens

    then hold down the power button

    and pressing enter when a message pops up

    this will clear all settings in the box

    if that wont work leave it unplugged from the wall for a day or two

C-D370 error code for Copier KONICA-MINOLTA C252

this has to do with what they call NAVRAM IS C
To troubleshoot the error:
1. Reset the code by pressing stop-0-7-1-3-9. This will display a "*" on the LCD. Press this button.
2. Perform a Data Clear and then perform the Setup Procedures from the beginning.
3. Perform a NVRAM Recovery Procedure. Please see attached document. To view the PDF, Adobe Reader® must be installed. Adobe Reader® can be downloaded for free from RRUPTED/need to be reset BUT that will clear all the current setting especially if print to it.if you are willing to try ....
you should have a Tech do this...
good luck

My boombox is displaying the word "Protect" in the display. ???

The protect message indicates that there is a problem with the final stage of the amplifier section. This unit will require repair as a reset will not clear this. There is an audio amp IC inside that needs to be replaced. Figure on about $15 or so for the part.

The protect indication is because of a fault detected in the amplifier section. If this appeared occasionally before and cleared itself, it suggests bad connections. If you know how to solder, open up the unit and resolder any connections that appear grainy or have rings. That may solve the problem.
