f3161

I have an F3161. When it decodes a tone it beeps for about 1 min. I am not sure how or where I stop it from beeping. Any help will be appreciated.

I understand that I must program one of the buttons to CALL in order to set the tones. I also see that in the channel list under 2 tone, you can program one of the 2 tone signals from the 2 tone list. If there are multiple 2 tone signals I want to send out on a single frequency, is there a way...
