MD788/788G
User-centered Design : The large-size color display allows good visibility even under extremely strong light. And the seven programmable keys facilitate your communication in various conditions.
Superior Voice : With the combined application of narrowband codec and digital errorcorrection technologies, MD78X/78XG mobile radio is capable of ensuring you superior voice under noisy environments or at the edge of the coverage area.
Versatile Services : In addition to conventional communication services, MD78X/78XG mobile radio features rich data services and selectable functions such as Text Message, Scan, Emergency, Channel Steering.
Full-duplex Communication : Realize simultaneous two-way voice communication by utilizing TDMA two time-slot technology. And there is no need to push the PTT during calls. Full -duplex call can achieve the same quality as phone call.
