Hi,
I do not know the AR very well but if they are anything like the MC’s they need to have their ‘level 2’ commands unlocked with the below command
at!entercnd=“A710”
After this they should respond correctly. I have attached a file (which I sent to a customer previously, hence the comments) showing an MC being taken into factory test mode and running the transmitter up against DCS 1800 (2G).
Regards
Matt
