The 536HP did have some issues early in its production with dim backlights and the real time clock (RTC). I purchased mine at the end of 2015 and did get the clock problem but the backlight is fine.

Someone here will likely remember when these issues were corrected.

The above is pretty much correct, I think the RTC was more of an internal battery problem. Uniden offered a recall to deal with this issue. Whether all scanners were fixed is another question.

I have 3 used 536s, 2 are earlier models. None have any type of display issues. But what's the real time clock issue and how can I tell if I have it or not? They are both in different vehicles and I don't record with either. Thanks

If upon every boot it tells you it’s lost the clock, you have that issue. But if you aren’t recording, it doesn’t matter.

Uniden ran a repair campaign for a few years to fix the issue but it’s been several years since that ceased.

FWIW, I never bothered sending mine in for repair. I've used the radio for 9+ years now with no problems.

My 436 went in for repair under the campaign Uniden offered...
Been running fine ever since...
Got it sent in just before the repair campaign ended...
There was no charge and they paid shipping both ways...

As Enoji has already noted, if your scanner still had the RTC battery charge issue, you would be seeing the nag to set the clock when you booted the scanner up. The display fading, that also affected some of these same units, likely would have surfaced by now for you as well, if it either had not been previously fixed.

Uniden ran a repair campaign for a few years to fix the issue but it’s been several years since that ceased.
The 'repair campaign' was announced in October of 2015. Since Uniden determined what the problem was, and set up a process on getting units repaired by this time, it stands to reason that corrective measures were probably put in place for the assembly process so that newly manufactured units did not go out the door with a ticking failure 'bomb' in place. So, at some point, earlier than the start of the repair event, (October 2015), new 2015 scanners coming off the line would have already had whatever parts needed already installed. The 2015 production unit you have may well have been assembled with the updated parts, rather than waiting for someone to have sent it in for repair.

And just to add to @hiegtx post...
My 436 (From above post) was manufactured in 2014...
Both my first 436HP, as well as my 536HP, were 'initial production' units. The original 536 had been swapped by Uniden because of the background buzz issue. Then, when the RTC & display campaign came out, both the 436HP and 536HP were sent in.

My second 436HP was built in 2016, so long past the original issues, which were corrected in production before my 2nd 436 was purchased.

Even though my SDS100 was also an initial production unit, I never had the 'solder joint' issue that affected a number of others. Pure luck, on my part.
