@chongqingfengfan: Eight tones, eight groups, one listen. The GP328 Plus carries Tone Tagging — eight different ringing tones, assignable to eight specific users or talkgroups. That is audio caller identification. The radio tells you which group is calling before you answer, on a build with no screen to read it from. On a shift where the supervisor is one of eight people who might key up, the tone decides the order of work. Answer this one now, that one in ten seconds, the third after the current job. Set the mapping once at commissioning and it holds. Signalling on this radio runs Quick Call II, DTMF and limited MDC1200. VHF 136-174 MHz at 5 W, UHF 403-470 MHz and 450-527 MHz at 4 W. Send the band and the quantity and we will price it. #ToneTagging #AudioCallerID #AnalogPortable #RadioDealer
