51  I have 5 RT1 radios, just upgraded and purchased 5 RT81 radios. How do I get the RT1 to communicate with my RT81 radiosr???
RT81 is DMR radio, RT1 is analog radio, if you make them communication, pls set RT81 in analog mode
Secondly keep RT81 and RT1 frequency and CTCSS same, after done the steps, pls try it again
Any questions, pls feel free to contact us

54  We purchased RT22 in the past and were really happy with them. We purchased more of the same but found out that the ones we had previously cannot communicate with the new ones. Is there a way to be able to have them paired with each other so we can use all of them.
Two radios can communicate, you have to make sure that frequency and CTCSS is same
Pls set same frequency and CTCSS between old and new RT22 radio in software
Here's a blog on ‘How to programme RT22?’ for you reference, pls kindly the link as below

56  Hi. The RT82 CPS truncates contacts file at line 65536 (Microsoft Excel limit?) during import. So there is no way to import 100.000 contacts as declared.
Also the csv file is truncated, not only the imported data. Thanks
Hello Nicola Gualteroni,
Pls tell me your RT82 firmware version, ERC or CSV?
If you want to truncate 100.000 contacts, pls truncate in here
