Kirisun TM840
Digital Mobile Radio
The large-sized, full color display enables the access to desired information easily even under bright sunlight.
TM840 supports multiple languages including English, simplified Chinese, German, French, Turkish and Spanish.
TM840 provides four programming keys, providing one touch operation such as Text Message or Voice Calls.
The Intelligent TM840 supports various voice call types, including Private Call, Group Call, All Call and Emergency Call, as well as data services, e.g. Text Message and Data Transfer.
Enhanced digital encryption and scrambled analog call feature facilitate the management of the calls between team members and ensure the privacy of communications in any chosen mode.
Integrated LIP (Location Information Protocol) enables the real time tracking of the mobile radio.
TM840 supports various analog signaling types (MDC1200, DTMF, 2-Tone and 5-Tone), various squelch control types (CTCSS/CDCSS), thus providing compatibility with existing analog communication systems.
TM840 supports supplementary services such as Radio Check, Remote Monitor, Call Alert, Monitor Channel, Permanent Monitoring, Kill, Stun and Revive, Transmit Interrupt.
TM840 is designed with second accessories ports via the rear port of the mobile, e.g. emergency footswitch or Telephone Interconnect (via DTMF signaling). It is also possible to support simplex voice communications between a radio and a telephone user. It allows a radio user to make a telephone call or a telephone user to make either a Group or Private Call to radio users through a Private Automated Branch Exchange (PABX) or a Public Switched Telephone Network (PSTN).
TM840 supports scanning of analog voice and signaling, digital voice and data, and also mixed mode scan including analog and digital signals.
TM840 reserves standard interface for any third party to further develop desired functions (such as Record, Bluetooth, RFID, and encryption Algorithm) with the optional board.
