I accidently hooked up my test leads to my 8921a wrong and introduced high Watts into the duplex out socket .Removed the a23 module and found the cr203 And cr501 burnt out in the duplex switch .I have replaced them and the unit Seems to be working again .Can anyone suggest simple ways to check the Duplex and ant in section to make sure there isn't any more parts damaged .
