BCD536HP time/date

[scannerman200]

Bought a used, very good condition 536hp and it’s a 2021 make per what a Uniden dealer informed me. When I turn the scanner off and back on, the time is wrong and date. I am NOT getting the prompt to reset the time and date when I turn it on. I have ran the unit for over two days. Suggestions?

Did you buy it used?
If so I am trying to remember the charge cycle time to recharge the battery for the time clock.

Replacing the battery circuit CRT

After 16 months of use, my radio BCD536HP began with the problem of CRT. For me it is very expensive to send back radio to Uniden for repair. I disarmed the radius (experience in repair of electronic equipment is required), I found the small battery "defective" I think this battery is damaged...

Maybe double check the time zone setting.
There was an recall in earlier models due to a clock issue.
Joe Bearcat the uniden dude; might know which models/firmware wore affected

I think the time for a first time full charge is 50 hours. My 436 went through the RTC campaign when that first started years ago, but I had to send it back a couple years later because the battery apparently served its time. However, the reported NOT getting the prompt to set the date/time at power on is a concerning.

 

[buddrousa]

There was a firmware change that ignored the clock setting after said x seconds and started scanning automatically.

Not seeing the prompt to set the Time/Date when the scanner is turned on looks like it could be some other issue...
If the RTC is not holding it's Time/Date it should prompt to set it when turned on... If you don't set it, it should move on
after a few seconds and start scanning...

Just a note: The Time/Date is only really used with the Recording Function to time and date stamp the audio files...

What Firmware version is in that scanner?

 

[RandyKuff]

Curious... If it's not prompting you to set the Time/Date when you turn it on...
You say the T/D is not right when you turn it on... What Time/Date is it showing...
If it's not the initial starting point for the time and date after losing the RTC battery...
You may not see that prompt...

 

[scannerman200]

The date is sometimes off by a day and the time may be 30 min to an hour or more off

The date is sometimes off by a day and the time may be 30 min to an hour or more off

That explains why you don't see the prompt...
Wonder if the clock oscillator frequency is drifting or something...

I just looked at my SDS100's time... It's like 7min off... Hasn't been set in awhile though... Like several months since the last time it was
synced with the computer...

What happens when you go to Settings and set Date/Time? Does it change after you do this?

Bought a used, very good condition 536hp and it’s a 2021 make per what a Uniden dealer informed me. When I turn the scanner off and back on, the time is wrong and date. I am NOT getting the prompt to reset the time and date when I turn it on. I have ran the unit for over two days. Suggestions?

ProScan has an option to update the scanner clock once a day, using the computer clock. Option is located in the Options Scanner Specific tab.

So I left the scanner on, only on the menu screen for the recommended time. I’m in Alabama so I chose -6.0 as my time zone for central time zone. Turned it off and back on, the date is two days off and the time was way off. Not sure what’s going on. When charging the internal battery, does it need to be scanning or just on the menu screen?

 

[buddrousa]

Scanner Turned Off.

 

[scannerman200]

So from what I read, the scanner needs to be on to charge the battery. Are you saying leave it off and plugged in?

 

[tvengr]

The scanner must be plugged in and turned on 50 hours to fully charge the clock battery.

From the easier to read manual:

Some of the quirks. You can't charge the batteries with the radio on. You have to turn it off or, (recommended), charge them in an external charger. There is no "0" charge time setting for those of us who never charge the batteries in the scanner and want to use USB power. The alert LED and ring only (and always) stay on for 5 seconds. The internal battery used for the clock will go dead in about 7-10 days if you don't use the scanner and it will charge only when the scanner is powered on.

The first sentence is referencing the 436 batteries for using the scanner. It must be off.

The second sentence is referencing the RTC battery. Leave the unit on for a long time. When I had the 436, I used to simply leave it on all the time and turn down the volume if I didn't want to listen, just to keep the RTC battery charged.

 

[buddrousa]

Mine stay on and had forgotten from when I bought the 536 and 436 new.
It is my TRX-2 that says charging battery when plugged up to a USB and off.

Use this for my 536, works great

Since you bought it used, I'd suggest looking at the serial number, to determine when your scanner was manufactured. Many of the early production scanners had problems with the battery that maintains the real time clock not doing its job. Uniden had a service program to address this on those units, as well as some display issues. But that campaign ended some time ago.

See this Wiki page: Uniden Scanner Serial Numbers - The RadioReference Wiki

That will help you determine when your unit was built. If it was in 2014 or 2015, or the first months of 2016, it's possible that it was eligible for the repair, but the previous owner never sent it in. If you have the scanner connected to your PC, and are using ProScan, letting the software update the correct time & date would be the easiest path. Since you are also not getting the option, when booting up the scanner, to reset the time & date could indicate that that firmware update was skipped. Put the scanner in mass storage mode, and have Sentinel check to see whether a firmware update is in order.

As Randy has already noted, time and date are used to account for when recordings are made. A wrong date or time has no effect on actually scanning systems for activity. But if letting ProScan maintain the time & date for you is not what you want, then your option would be to send the scanner in for repair.

My unit was manufactured in 2021 or later, as it has the letter C and not Z
