    They have said if you open the unit to replace the battery it voids the warranty. Their words are there are no user serviceable parts inside... except the battery is in a battery holder so it can be easily replaced which kind of negates their argument... and I doubt if sued they would win this argument based off the use of a battery holder versus soldering the battery to the board. But that is their current viewpoint...

    Yeah, it's things like this that drive us all nuts. I'm happy you posted your resolution and that you did the work, and solved the issue. It helped me decide to do the same and see what happened with my unit. To me, it's like owning a car that starts behaving oddly or making a noise. What's the first thing we do? Open the hood to look around! LOL Sometimes it's an obvious issue we can fix at home, sometimes it needs to go to the dealer. Everyone will have their thoughts around this whole debacle, but at the end of the day, if it's fixed and we know that it's one of two possible causes or both in conjunction, a lot of people will be happier Kemper users. We can get back to making music with the thing, instead of getting annoyed every time we power it up!

    Yeah... I am glad I did it. Basically they confirmed my exact diagnosis... battery failure and firmware that exacerbated the issue... At least they FINALLY said what the problem is... but it took my posting for them to do it

    If it ever came down to it, having the battery in a battery holder that is meant so that it can be easily replaced would negate their definition of "non user serviceable" in a court of law... They probably need to rethink this whole stance


    Also, using standard TORX and Phillips screws as opposed to tamper proof versions would not do well for their claims there...


    I used to design medical devices as well and those had to use fasteners that the average person didn't have around or could get their hands on easily.

    Herself... "She" can fix it herself... please don't assume all guitar players or kemper users are male


    Also, having a battery inside that WILL need replacing constitutes a "User serviceable part" - especially since it is in a battery holder. If it were soldered to the board, that would consitute non user serviceable part. Believe you should check your definition of that term.

    When Kemper says it's not the batteries fault and the unit needs "repair" the conclusion maybe is, the unit is draining the battery?! Why don't they just tell us, what is broken? But it seems that is Kemper strategy also with other faults.

    I would be much better if they would just say what the problem is. Very disappointed. Personally, I am OK with swapping the battery every few months as it is literally under a 10 minute job. But for that matter, having a battery inside that will ultimately fail after some time and having changing it void the warranty is kind of ridiculous... So if you had a 5 or 6 year old unit and the battery fails you are supposed to send it back for them to replace? Just disappointed in their handling of this...

    no. as it turns out, that's the wrong conclusion.


    if you face the battery error issue, please contact support and we'll take care of the repair.

    and yes, opening up the unit voids the warranty.

    Please explain, then, why replacing the CR2032 solves the problem? You guys have been absolutely horrible about telling people what is going on with this issue!

    Since Kemper will not give any statement as to the "why" this has happened to so many.... I will give you my experience and fix


    I bought my profiler stage in December from UK dealer. Didn't use it much until February or so. Updated firmware and all was fine until about May. A firmware update in May seemed to start the dreaded clock setup error. Maybe this was a coincidence but all of the problems seen on the forum seemed to point to the same date which I find weird.


    Kept updating firmware when it came out and no fix.


    My problem was the same as many: turn power to the unit, clock setup error. Leave it plugged in for some length of time and still would show clock error at next boot. Unplug the power cable and the Kemper would always boot no matter what power state I left it in.


    I did file a warranty claim, but did not have the original box anymore and it just seemed something so small that it seemed ridiculous to send it back to Germany just to probably have the CMOS battery replaced,


    I used to design amps for Crate and Ampeg and loudspeakers for Dolby. I am a mechanical engineer, but I've done a lot of circuit design and programming. I don't get scared easily by taking things apart. So today I decided to just see what was inside and see where the battery was. Opened the unit up, replaced the CR2032 battery. Powered on. set the clock. Powered it back down. Unplugged unit power. Plugged it back in. Unit was powered off still. Pressed power button. Unit booted and was fine. No clock error. Did this MANY times. Working as expected.


    So apparently, Kemper got a bad batch of CR2032 batteries. And all seemed to fail at around the same time or one of the firmware updates exposed a bad battery situation. Why there is nothing in the firmware warning of a low battery or similar is beyond me. And why Kemper haven't owned up to the issue or said anything but "send it back" is also a bit beyond me. But basically the $1500 unit "failed" because of a $2 battery.


    Your mileage may vary. I don't recommend doing this unless you know what you are doing. And even then, it will probably void your warranty. But to me, knowing what the real problem was was quite important and I'd rather spend 10 minutes changing a battery than packing it all up and shipping it back and waiting with no explanation of the fix. That way I know what to do next time.


    But it did resolve my issue. I will update if anything changes but I would say it is fixed

    Thank you for sharing your behavior!


    Mine runs exactly like my early unit(s) prior to 7.1.3 did - plugging in the IEC turns the Stage on, regardless of the state prior to removing the IEC plug.

    Mine does the same thing since I started having the clock setting error. Before that happened, it operated as the other poster stated. It defaulted to last state before IEC power was disconnected

    The shear number of these having this problem all of a sudden to me doesn't seem like a hardware issue. Plus mine started this behavior directly after a firmware update. But maybe it is a hardware issue. I am holding on to mine at the moment as I can live with the annoyance as shipping it to Kemper is a problem for me as I got rid of the original box.


    Kemper have not come clean or been clear as to WHAT the problem is and WHY so many have had this issue all at the same time... I would feel better if they would just tell us. It doesn't give me a good feeling long term for such an expensive item

    It has happened to a LOT of us all recently. I have a profiler Stage bought in december. I filed a service ticket but am not in a hurry to send it back as I am 99% sure it is firmware related. And also I don't have the original box... nor a box big enough to send it back in.

    If the internal clock of your new PROFILER Stage always looses date and time when the unit is disconnected from the power network, it requires service. Sorry for the bad news and inconvenience, but this can't just be fixed by a software update nor by just exchanging the battery. Our service has a permanent fix. Please open a support ticket here and the situation will be dealt with professionally:

    Just to let you know, the clock issues has not other functional implications. So, it's safe to use the unit for guitar playing.

    Can you explain why this has happened to so many of us at the exact same time if it is a hardware issue? It started exactly after the updating to the last 2 beta firmwares on my stage. Maybe a coincidence, but doesn't seem to be.

    I am also in the UK. Bought my stage in December but didn't use it much until the last 2 months. For the last 2 firmware updates (unsure exact version I am on as I am not home right now), it has started this clock error thing. I checked yesterday for a newer firmware and nothing yet. With the first of the last 2 firmware updates, it would be fine with keeping the mains power on and only powering down the unit itself. With the last firmware update - the latest as of 9/6/21 - it doesn't matter if the mains are left on or not. When the Kemper is powered on, it defaults to the clock error problem.


    It truly seems firmware related. I am reluctant to send it back as it still works fine once I hit OK to the prompt. And if it were a battery issue alone, leaving it connected to the mains and just "soft" powered down SHOULD take the battery out of the equation as when connected to mains it is drawing some power to enable the soft power button to boot it. At least that is how most electronics like this that don't have a truly physical button disconnecting the power. I mean, your tube amp completely disconnects mains when you flip that switch. Versus your phone which is always "sleeping" and drawing some power even when powered off
