<br> Ok, i found it, it's on the main? board and can be seen in this teardown video:&#160; https://www.youtube.com/watch?v=leC-zSMbtfg&#160; around 15 min. in.<br> It's the DS1742W-150&#160; Dallas&#160; (top right)&#160; U640, at least for a TDS3054 (mine is TDS3054B).<br> <br> They seem hard to find nowadays, but there are some replacements, although also many fakes.<br> <br> Kees<br> <br> <br> <br> &#160;

<p></p> <p>Hi Afonso,</p> <p>thanks for the info, any idea where this DS1742 chip is hiding in the TDS3054B, on what module?</p> <p>Kees</p> <p></p> <p></p>

Hello, since a few days, my TDS3045B does not continue with the correct date / time after I power it off.<br> Each time I power it on, I have to set the new date / time, but it gets &quot;stalled&quot; after I power it off.<br> <br> Is there a backup battery to replace (not that I can find in the manual) or is there something else I can do to fix that?<br> <br> Thanks,&#160;&#160; Kees
