SuperiorVoice

With the combined application of narrowband codec and digital error-correction technologies, PD785/785G is capable of ensuring you superior voice in noisy environments or at the edge of the coverage area. In addition the adoption of the AGC technology also optimizes your voice. With a built in 1W speaker, PD785/785G ensures clear and crisp voice communication.

 

DurableBattery

Compared with an analog radio, PD785/785G can obtain an extra 40 operation time.

 

Higher Spectrum Efficiency, Higher Channel Capacity

Benefiting from the TDMA technology, PD785/785G allows twice the channels based on the same spearum resource. This is a big help to relieve the stress of increasing shortage in spectrum resou rce.

 

Dual-slot Pseudo Trunk

With this feature, the free slot can be allocated to a member that needs to communicate, effectively enhancing frequency efficiency and allowing you to communicate timely under eme rgency situations.

 

Secure Communication

Besides the intrinsic encryption of the digital technology, PD785/785G provides enhanced encryption capability (such as 256-bit encryption algorithm) and the Scrambler feature (selectable).

 

Versatile Services

In addition to conventional communication services,  PD785/785G features rich data services and selectable functions such as Text Message. Scan, Emergency, Man Down (optional). vibration Auto Regist ration, High-speed Data Transmission* and Lone Worker.

 

FurtherDevelopment Port
