I have got my manual 31 minutes after e-mailrequest (3 mail redirections between Zetron people included).

I've got it without any problem from Zetron UK (via email).

Hello, I seek for a manual for Zetron 37 RepeaterMan. I need a method of remote programming the device via DTMF codes. I found only a manual of Z 38 with remote control codes - do these 2 models differ a lot? Does anybody know the place where I can download the manual from? Many thanks - and greetin...
