MD785
Highlights
Clear Communication
With the latest audio processing technology and in-built speaker, the MD785 offers you outstanding audio quality in loud environments and near the boundary of radio coverage
Analogue or Digital
It is possible to configure both analogue and digital channels. This enables the user to utilise mix mode scan and switch between the two, making it simpler to migrate to digital
Packed with Functionality
Besides the traditional communication features, the MD785 offers numerous digital functions, including text messages, GPS (optional) and safety features such as lone worker alert and emergency call
Intuitive Operation
The high-resolution LCD screen offers a clear display, even under difficult light conditions. The large keyboard and ergonomic programmable keys facilitate efficient and productive communication
Versatile Applications
Combine the MD785 with your systems to automate actions (telemetry) or expand your communications solution with Hytera XPT Trunking (Tier III) to maximise your channel management
Functions
Telemetry
Allows the monitoring and control of external devices via the radio.
Priority Interrupt
Send a priority transmission to interrupt other calls, ideal for important, critical messages.
Intelligent Audio
Combining noise cancelling technology to remove nusiance noise from the transmission, delivering clear communications.
Priority Scan
Allows the radio to automatically scan and switch the user to receive a priority call if transmitted.
Pseudo Trunking
Using pseudo-trunking, a Hytera patented technology, slots can be shared to improve capacity usage with transmissions either direct to device or to a repeater.
XPT
Hytera XPT (Extended Pseudo Trunking) enables you to use limited spectrum resources more efficiently, dynamically assigning channel resource without needing a dedicated control channel.
Lone Worker
The Lone Worker feature uses a timer in the radio to measure inactivity. If the timer expires, a warning is issued, and if there is no response to that, the alarm is triggered.
Emergency Mode
Raise an alarm with top priority to a base station or to other radios with the pre-programmed emergency mode, identifying the ID of the person issuing the alarm.
GPS
(G) version only (via separate antenna), enabling location based services to improve safety and control.
