I have a UHF MCS2000 with a Type 2 head.

I want to use the "Phone" feature to transmit a DTMF string. (I don't have a DTMF mic ).

I can get the MCS2000 to transmit a DTMF string BUT it seems to transmit 3 other tones before/during the "please wait" message - after this I press the PTT and the correct DTMF string is sent.

I want to remove the "3 pre-tones". I think it might be to do with the "Access/Deaccess codes". The default settings seem to be *1P# . I guess this is used to gain access to the phone network and is unnecessary for my application - in fact it stops it working!!

I have tried completely removing *1P# but this has the effect of putting the MCS2000 into continuous transmit mode!!!

I though about just having *# inserted but decided to first check out what others thought I should do.

Any ideas?

Thanks

I had this issue and, while I recall it took a while and some fluttering around to find a solution, I confess I don't quite recall what the solution was. I think I created a second phone system, defined the access as a single space, and used Phone System 2.

Thanks for the feedback.

Can you remember what you inserted - maybe * # or *2 #

The default access code (*1P#) transmits 3 tones - although there are "4" characters ie. * 1 P #

Maybe I just need to insert a " * " or a " # "??

Thanks

Well I did some more reading and experimenting.

The "P" in the default phone access code stands for "Pause" - this explains why I got 3 tones with the default 4 digit code *1P# - and there was indeed a pause after the *1.

So I just replaced the *1P# with P in both the Access and Deaccess codes. (When I previously inserted nothing , the MCS2000 TX'ed continuously!!)

This seemed to do the trick and I now TX just the DTMF codes.

I also did some tweaking to the DTMF Initial Delay (2 secs) , Digit Duration (200ms) and Interdigit Delay (150ms). This was just guess work but the repeater immediately recognised the DTMF string !!
