I have just received a new SDS100E and are trying to purchase a DMR Upgrade Key from my.uniden.com. I put in the last 9 digits of the ESN and the 3 checksum digits but it says, ‘The Checksum you entered is not valid. Please recheck your input to ensure that you have entered the 3 digits of the SUM value correctly.’
The checksum is 0FC and I am definitely entering zero F C, any assistance gratefully received.
Thank you
Keith
