Highlights


AM780T DMR & Analog DualMode Radio Integrated With Remote Control & Public Telephone Interconnection


1. Ultra-large Channel Storage Capacity

The device is equipped with a high-performance, large-capacity storage module, featuring 1,600 built-in channel resources and supporting 100 independent zone divisions, with up to 16 channels configurable per zone. The hierarchical zone management structure offers clear organization and flexible scheduling, fully meeting the routine communication dispatching needs of multi-team, multi-zone, and complex commercial scenarios.


2. High-definition Large-screen Visual Operation

Equipped with a 2.0-inch 320*240 high-definition color LCD display, the screen delivers delicate colors and clear images, supporting full-viewing-angle visibility. Paired with a user-friendly soft keypad control scheme, the interaction is simple and efficient, supporting real-time time display to optimize the overall user experience and adapt to visual operation needs in various working conditions.


3. DMR Dual-slot Efficient Communication Technology

Adopting the industry-standard DMR digital system and direct-mode dual-slot communication architecture, a single frequency can carry two independent parallel conversations, doubling communication throughput efficiency. This effectively saves spectrum resources and reduces frequency usage costs, ensuring stable, real-time, and congestion-free communication in high-density business communication scenarios.


4. Digital-analog Dual-mode Compatible Transition

Supports adaptive switching between digital and analog modes, fully compatible with traditional analog two-way communication systems. Without the need for a complete replacement of the existing equipment system, it enables a seamless and smooth upgrade from analog communication systems to digital communication architecture, significantly reducing equipment iteration costs.


5. Convenient SMS Send and Receive Function

Equipped with a full-keyboard intelligent editing module, it supports quick text editing and two-way SMS sending and receiving. In scenarios where voice communication is limited, instructions can be conveyed and information retained through text, enriching communication methods and adapting to professional scenarios such as silent operations and precise information reporting.


6. DTMF Telephone Interconnection Function

Supports relay-linked DTMF dialing communication. Through preset numbers or manual dialing, it enables interconnection and intercommunication between the two-way radio system and public telephones or mobile terminals, breaking down the communication barriers between private and public networks, and building an integrated all-domain communication system.


7. Remote Emergency Alarm and Lone Worker Function

Built with an independent personnel monitoring mechanism, it automatically triggers local and remote alarms when no operation is detected within a preset time, and can simultaneously upload alarm signals to terminals and relay devices. Specifically designed for lone worker scenarios, it can proactively warn of sudden dangers, ensuring comprehensive personnel safety.


8. Digital Dialing Flexible Calling

Supports digital ID precise addressing call mode. Users can manually input the device ID via the keyboard to quickly initiate individual calls or group calls, with precise call targeting and rapid response, adapting to refined and customized communication dispatching scenarios.


9. High-definition Digital Voice Calls

Utilizing high-end narrowband voice codec technology and intelligent digital error correction algorithms, it effectively filters out environmental noise and repairs transmission loss. Even in complex and noisy environments or at the edge of signal coverage, it ensures clear, transparent voice and stable calls, guaranteeing efficient and accurate voice communication.


10. Multi-function One-key CallIntegrates comprehensive one-key intelligent operation and maintenance and calling functions, including SMS push, voice call, missed call reminder, remote monitoring, device online detection, terminal remote kill and activation. It enables multi-dimensional management such as device status control, remote security control, and missed information reminders, adapting to various complex operation control scenarios and improving system operation, maintenance, and dispatching efficiency.
