Doesnt look like there is a solution for this. Mine is just taking up too much space for no reason at home at the moment. Its also such a terrible thing to load into the car and take all the way to Mustek for diagnostics. I suppose I will find motivation when LS reappears.

I have also opened it up and disconnected the bettery for a few minutes to do a hard reset but the issue persists.

Hi all. I am having this same issue after my battery ran flat during moving home. I have tried these steps but when i hold the battery button down, nothing happens. The decice does not reset. Am i missing something. At the moment the battery does not charge and the moment i remove the power cable it turns off.

I've had the software update done quite some time ago, and I have always had that clicking. I am sure i mentioned it somewhere in the early pages of this thread. It happens at any time of the day regardless of the batteries being fully charged or connected items being on or off. I do not have lights connected to mine so cannot confirm the dipping when clicking occurs. I have not noticed any such issues with the connected equipment.

Thank you

Hi all, Can anyone advise on a suitable solar panel to add to these units? Also, is it worthwhile actually adding a solar panel to one of these?

You should be able to press the up and down arrows to change display values (without first pressing the menu button)

Same with mine since the software was updated. Noticed recently it has dropped to 0% and got stuck there. Pressing the battery button resets it to correct reading again.

When I took Mine in on 13 March, they said they would have the updating "device" until then end of the day, as it would be going to PE on the 14th, and then this would be sent to another branch after a few days as all branches are sharing one of these mysterious devices. If you have a Mecer unit then contact Mustek PE asap.

Yes I have. If it is a Mecer unit, contact Mustek support in Richmond to arrange. They will be getting the device to update firmware again in a few weeks. Mine took less than an hour to update.

Thanks 👌

Had my firmware updated at Mustek yesterday. Been through two sessions of LS since its been returned, and it has charged back up to 100% on both occasions. So far, so good considering mine has been sitting at 0% for the past 2 weeks or so. According to them, the upgrade requires a specific "device" and cannot be done remotely or by anyone else. They currently have only one of these devices that is shared between branches. I had to rush mine in yesterday as they only had this device until end of the day before it would be sent to a different branch. They will next have one of these devices in CPT in "a few weeks." Just a question regarding charge current, I have set mine to 40%. I only lose around 20% charge during LS so there is more than enough time to charge up to 100%. Would this make any difference for the batteries or should I just leave it at a higher or even 100% charge current?

Mine does the random 3 beeps as well. Very annoying. I also noticed it randomly makes that clicking noise, same as when it switches from battery to mains. Is CNBM in JHB only? I have not heard back from Mustek yet but I assume there would be a long waiting period to get mine back just for them to do a simple firmware upgrade.

I managed to charge mine for 8 hours straight before using it, didnt make any difference.
