I am using a SDS200. Is there a way to go back to scanning after using the mass storage ?? Where do I find the ESN and Checksum ?? The serial number on my scanner the one on the back has a Z while the one on the menu has a 2 in the same place. Which one is correct??
Just unplug the USB connection... The scanner will reboot and to return to scanning. Not a bad idea to use your computer's "unmount" or "eject" function for mass storage drives to protect the SD card before removing the USB connection.
The serial number (SN) is on the back of the scanner, the electronic serial number (ESN) is in the scanner's menu system:
Menu button ---> Settings ---> See Scanner Information ---> Firmware Version.
The last line on that screen is the 14 digit ESN followed by the Checksum after the dash. They are both correct.... if you are purchasing upgrades, when you register your scanner at my.uniden.com you are asked for the SN. When you actually purchase the upgrades, you will be asked for the ESN and the Checksum. On that purchase page, the first numbers of the ESN are already entered there, just fill in the remaining ESN numbers and the checksum.
Note: the "Z" in the SN is replaced with "260" to get the ESN.
