    was riding along and everything was fine. Stereo stopped playing and has a constant OCER message. What can I do to fix it? Is there a reset button maybe?

I have model kdc-138 & it show "ocer" on the screen & nothing works-radio or cd player...help???


Please check this message. If it is DCER, not OCER, you have a short-circuit in the speaker wiring or a wire is touching the vehicle chassis. Until the wire is fixed (insulated or replaced), the receiver will remain in the Protection mode. This keeps the short from permanently damaging the unit. After you insulate all of the wires, press the RESET button, to the left of and below the volume knob.

If the error persists, then you need to have the receiver professionally serviced. The short is probably inside the receiver itself.

I hope this helps. The troubleshooting guide is on page 18 of the manual. It is available from Kenwood here: http://manual.kenwood.com/files/B64-3898-00_00_KW.pdf . The image of the reset button position is on page 3.

My system just stop working and its only blinking ocer


OCER indicates that the unitis in protect mode. First press the reset button (tiny pinhole button). If the unit comes back on saying OCER then most likely there is a short or a grounding problem with the speakers or speaker wiring. Disconnect all speakers and press reset again. If OCER still shows up the unit needs service. If not, connect each speaker once at a time until the unit comes back in OCER to narrow down the location of the unwanted DC signal.

Turn it on in it says ocer


Here's the Manual for your KDC-138 deck...

http://kenwoodusa.com/UserFiles/File/Global/Consumer/Manuals/kdcmp238.pdf

On Page 18 it describes the error that you're seeing... let me re-type it here:

PROTECT / DCER: The speaker wire has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated.
-- Wire or insulate the speaker cable properly and press the reset button

I found on Page 3, the reset button is located just below and to the left of the volume knob...

I hope that helps.

Error message on screen will not go away


Hello bigdsketch,

The "DCER" error is caused by one of the speaker wires shorted or grounded or a shorted voice coil. Remove the speaker wiring one at a time to determine which one is causing the error, then repair or replace the defective part.

You may need to press the reset button (small recessed button to the lower right of the volume control) after the problem is corrected.

Hope this helps.

I turn on the radio and OCER is shown in the faceplate and it doesn't do anything else.


Hello miguel200819,

The "PROTECT/DCER" error is caused whenever a speaker wire is shorted or grounded by contact with the vehicle frame. Locate and repair the shorted/grounded wire or run a new one and then "reset" the receiver by pressing the reset button to the lower left of the volume control. If this does not work, the receiver is faulty and needs to be serviced.

Hope this helps.

Kenwood KDC-138 Operation Problem


Here's the quote from the manual regarding "dcer": "The speaker wire has a short-circuit or touches the chassis of the vehicle and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT/DCER" code does not disappear, consult your nearest service center "

I believe the manual can be downloaded from crutchfield .com after you go to the Kenwood KDC-138 page on their website. The reset button is either on the lower left of the face or, removing the face, on the lower left of the body. Hope this helps you.

OCER


ok, there is a default button right next to the SRC button on the face of the radio. take a pen or small srew driver and point the little button (it looks like a hole) hold it for about 10 secs and it should reset. when ocer flashes on the screen, this means that one of your speakers is either trying to go bad or is bad. keep ur volume low if u have factory speakers
