Friendly interface display and key design
The MD780/780G features a large color LCD display that makes you visible even in the outdoor light, and seven programmable keys enable you to quickly achieve the features you need to improve your communication efficiency.
Reliable and durable quality
The MD780/780G is of high quality to the strict U.S. military standardmil-STD-810 C/D/E/F/G and IP54 industrial protection standards, providing excellent performance in a variety of harsh working environments.
Noise suppression, better voice
The MD780/780G uses advanced narrowband voice codec technology and digital error correction technology to get clear voice in noisy environments or on the edge of coverage. The use of AGC technology also greatly optimizes the effect of voice reception.Built-in 5W high-power speakers ensure clear sound and loudness, making it easy to keep your communications flowing.
Higher spectrum utilization, channel multiplier
TDMA dual time slot technology greatly improves spectrum utilization, and the MD780/780G can accommodate more than twice the channel on the basis of the original frequency resources, greatly reducing the pressure of the increasing shortage of spectrum resources.
Dual time slot virtual cluster function
As a unique function of Haineta PDT products, the dual time slot virtual cluster technology can assign the current idle time slot to the group member who needs to call, which can better improve the frequency band utilization.In some emergencies, help you deliver important information in a timely manner.
Voice encryption
In addition to providing encryption inherent in digital technology, the MD780/780G provides a higher level of encryption capabilities (such as 256-bit encryption algorithms) and spoiler capabilities (optional).
Rich business capabilities
In addition to traditional communications services, the MD780/780G supports a variety of data services and optional features such as text messaging, scanning, emergency alarms, tailpin alarms, pin channel switching, automatic registration, high-speed number transmission, and individual operation.
Open secondary development interface
The MD780/780G provides an open front and rear panel secondary development interface, allowing users or third-party vendors to develop richer applications to extend intercom functionality.
Optional interface
MD780/780G supports optional interface, allowing third-party vendors to develop a variety of applications and intercom connected, control intercom to expand its functions, support ingress with the functions of call recording, encryption and so on.Check with API programmers for more information.
Analog-Digital Dual-Molded
The MD780/780G supports both digital and analog modes, compatible with existing conventional analog systems and ensures a smooth transition from analog to digital.
Full range of voice calling features
The Intelligent Signaling provided by the MD780/780G supports a variety of call modes, including one call, group call, full call, and emergency call.
GPS positioning
The MD780/780G supports viewing GPS location information and sending GPS text messages.
Data business
The MD780/780G supports the function of sending a call and group text message.Third-party APIs (GPS, intercom registration service, intercom and call control, telemetry, digital transmission) or telemetry control intercoms are also supported.
Attachment extension
The MD780/780G supports third parties to develop attachment extensions through the front and rear panel secondary development interfaces of the platform (the rear panel secondary development interface already supports the tail pin channel switching and tail pin alarm).
Support for a variety of advanced analog signaling
The MD780/780G supports a variety of analog signaling, including HDC1200, DTMF, 2-Tone, and 5-Tone, and more noise-cancelling control types (sub-audio/subtone digital), thus providing more room for functional expansion.
Complementary business
The MD780/780G supports additional services such as walkie-talkie, remote listening, call prompts, activation, and remote shooting.
Support for multiple language displays
Support s13 languages (English, Chinese Simplified, Chinese Traditional, German, Spanish, French, Italian, Polish, Russian, Turkish, Korean, Greek and Portuguese) are available for the user to choose the language they need.
One-click call
The MD780/780G-supported one-click call feature includes text messaging, voice calls, and complementary services.
Scanning
The MD780/780G supports scanning pure analog voice and signaling, pure digital voice and data, and analog and digital activity in mixed mode.
Roaming
The MD780/780G supports automatic roaming at all sites of the IP interconnect system.
Voice and data encryption
The MD780/780G supports analog scrambling frequencies, as well as Advanced Encryption Standard (AES) and ARCFOUR (ARC4) encryption algorithms for digital voice and data.
Analog/digital telephone interconnection (via DTMF signaling)
The MD780/780G supports one-way calls between intercom users and phone users. Allows a walkie-talkie user to make a phone call to a telephone user, or a telephone user to make a call or group call to the intercom user.This feature uses commercial off-the-shelf (COTS) analog telephone devices and ordinary old-fashioned telephone services (POTS) to connect walkie-talkie users to a public office telephone system (PBX) or a public switching telephone network (PSTN).
Software can be upgraded
Convenient upgrade features allow you to add new features directly through software upgrades without having to purchase a new machine.
