At Mayfair Mall, we use the Motorola XTS-1500 radios. I was wondering if anyone could answer this. When I key up my radio, it will not give me the talk permit tone. However, if i quick press the button and let go right away, it sounds the triple beep. Anyone know why the radio is doing that? I thought that when you press & hold the ptt button your supposed to get the triple beep.
