Caltta Professional Digital Mobile Radio PM790
The PM790 is a high-performance professional digital mobile radio meticulously developed by ZTE Caltta in compliance with the PDT/DMR trunking standards. It features rich intercom functions, excellent RF performance, diverse frequency band support, simple and convenient operation, and clear and loud audio, which can fully guarantee the frontline vehicle-mounted communication requirements. The standard-sized device is easy to install, adopting a screen/navigation keypad interaction system, a high-strength dual-color housing, a rugged alloy frame, and high-grade waterproof sealing, with resistance to vibration and impact, ensuring durable operation even in harsh vehicle-mounted environments. The PM790 will deliver a comprehensive digital communication experience for professional users, providing solid assurance for reliable communications.
It supports PDT/DMR digital trunking mode and conventional modes (direct/repeater/ad-hoc network). It delivers high-quality digital trunking voice services that meet the high standards of professional communication, enabling fast responses to calls from professional customers anytime and anywhere. Compared with traditional analog technology, the PDT/DMR dual-slot technology can provide double channel capacity, which greatly alleviates the growing pressure of spectrum resource shortage.
Digital-analog Compatibility to Protect User Investments: In addition to the digital trunking and conventional modes, it is also compatible with analog trunking and conventional modes, allowing operation in the user's existing network environment with stronger applicability, thus preserving the existing investments of professional users and supporting the smooth transition of professional user networks.
Standard Size for Easy Installation: The overall dimensions of the device meet the 1DIN standard of the automotive industry, making it convenient to install at the original car audio position. An independent mounting bracket is also provided for stable installation at other positions.
Excellent RF Performance: With carefully matched and optimized classic superheterodyne hardware circuits combined with a high-gain external vehicle-mounted antenna, the device boasts outstanding RF performance and higher receiving sensitivity, enabling two-way communication connections over longer distances.
Clear and Loud Audio: The meticulously optimized audio circuit and structural sound cavity design, paired with a high-performance noise-canceling audio encoder, ensure loud sound while maximally preserving the fidelity of the user's voice. Even in the noisy environment of frontline engineering vehicles, users can accurately identify the caller and clearly hear the call content.
Excellent Human-Machine Interaction Design: Based on the usage habits of professional customers, the classic human-machine interaction process is deeply developed to conform to the operation and maintenance conventions of professional vehicle-mounted terminals, allowing professional users to get started and operate proficiently quickly. Meanwhile, the adoption of components such as a high-volume speaker and large semi-transmissive LCD screen further enhances the user experience for professional users, helping them successfully complete tasks in various work scenarios.
Rich Configurations and Complete Service Functions: Optional configurations such as Bluetooth and BeiDou positioning are available to adapt to the usage demands of different industries and scenarios. It supports functions such as caller location reporting and five standard supplementary services, with optional call recording to ensure no missed calls and more convenient personnel management.
Highly Expandable External Interfaces: Through the tail pin interface, users can expand and develop a variety of featured functions. In addition to traditional audio interfaces and serial interfaces, it is also equipped with rich expansion functions such as ignition detection, local voice broadcast, and GPIO control.
Complete Secondary Development Interfaces: Through the secondary development interfaces, users can easily integrate the vehicle-mounted terminal into their own systems to expand more use cases.
Software and Hardware Encryption to Safeguard User Security: The hardened professional two-way radio real-time operating system guarantees the terminal's security. It provides 40-bit basic voice encryption, and optionally supports AES 128/256-bit high-level software encryption or TF card hardware encryption to protect users' call information. It also features lone worker protection and one-touch emergency alarm functions to ensure users' safety during operations.
Rugged and Reliable Quality: The whole device meets the IP54 protection rating, making it suitable for vehicle-mounted operations. Multiple indicators including impact resistance, vibration resistance, and solar radiation resistance meet high reliability standards, making it competent for various harsh working environments.
