208H Help please!

[argo]

I can't program Freq. from the handset all of a sudden! all the other functions on the Mic appear to be working. I have re-read the manual and am doing what it says vfo/lock....ent.C(T-off) it beeps like its getting the cammands but then nothing!. I've reset the whole thing several times.
Any help would be welcome, Does Icom offer any support for something like this?

OK I found the culprit! I plugged in my Handset from my other Icom and it works ! so I'm off to ebay or something to find a HM-133 Mic

Thanks for listening
