I-Kirisun DP990 High-end Digital Walkie Talkie
Isekela izindlela ezine: i-analog evamile, idijithali evamile, i-digital trunking, kanye ne-MPT1327 analog trunking, ehambisana nezinhlelo ezikhona ezijwayelekile ze-analog, okuqinisekisa ukuguqulwa okushelelayo kusuka kumikhiqizo ye-analog kuya emikhiqizweni yedijithali. Umsebenzi we-trunking ungasekelwa ngokugunyazwa. Ngasikhathi sinye, ingakha uchungechunge lwezixazululo zesistimu yokuxhumana yedijithali eneziteshi ze-Kelixun ezidluliswayo zedijithali kanye neziteshi ezifakwe emotweni, ezinganweba imisebenzi eminingi njengokurekhoda nokuzulazula, futhi ihlangabezane nezidingo zesicelo sokuxhumana sezimboni ezahlukahlukene ezinezindleko eziphakeme kakhulu. kanye nemisebenzi ecebile.
