You can find your ESN in the menu under Settings > See Scanner Information > Firmware Version as the SN value. For example:
38426088123456-1AB
Also, if you are using this number to purchase the upgrades, when it asks you for your serial number, you’ll see that while the SN is 14 characters (excluding the 3 character checksum after the - symbol) you can only enter 12 characters.
The way you enter this in is by replacing the 260 at the 4th position with the letter Z. So for example, if your SN (without the - and checksum at the end) is:
38426088123456
You would enter:
384Z88123456
This wasn’t documented on my.uniden.com and the only way I figured this out was by looking at a previous registration I had done (and forgotten about this trick)
Your ESN when registering on my.uniden.com will actually be the SN value minus the checksum. For example:
38426088123456
And then the checksum will be the last three digits at the end of the SN from the scanner. With the example above, that would be:
1AB
Hopefully this was t too repetitive in explanation but it’s confusing so I figured more explanation is better than less.
Enjoy your SDS200 and upgrades!
