Vertex Standard VX2200

Can someone help me. I am new here.
I have successfully program a VX2200 and the transmit is fine but on the receive the sub audible tone doesn’t seem to work although the CTCSS encode/decode tone is set.

Wondering if it is the software version or the transceiver?
I am using the Version 3.01

I think more information is needed in order to answer your question? What are you trying to program the radio to do? Are you trying to get into a repeater? Which repeater and what are the parameters of that repeater?
