Rx-RM750, DMR Mobile Radio

Overview

Overview

Rx RM750 is a base & Mobile station and also function as single frequency repeater function (Optional) solution. As a single frequency repeater, Rx-RM750 allocates one timeslot to receive a signal and the other to transmit it at the same frequency, using DMO (Direct-Mode-Operation) mode to extend radio coverage.

Key features

  • Base Station/Repeater Dual Modes
  • Extend DMO (Direct-Mode-Operation) Communication Distance
  • Power-on Password
  • Cost-effective DMR Repeater Solution
  • Good heat dispersionThe high-quality built-in fan provides sufficient airflow for operation within the specified temperature without derating, and thus enables Rx-RM750 to operate stably for long hours.
  • Multiple sites via IP (Factory Options)RX-RM750 supports network connection via the IP port to form a private radio network, thus meeting data and voice communication needs for wide coverage and dispersed locations.
  • Repeater Power Backup (Optional)With DC/AC dual power sources, when DC power supply is unplugged, the device automatically turns on to an AC power source. The two auto-switchable power sources serve as each other's backup, thus delivering more flexibility and stability.
  • Analog/Digital Back-to-Back Interconnect (Optional)Rx-RM750 supports different operation modes of analog and digital to interconnect for voice crosspatch, allowing analog users to communicate with digital users and vice versa. This delivers a smooth transition from analog to digital.
  • 2/5 Tones
  • Colour Code
