New model RETEVIS RT84


RT84 Main Futures:

  1. Broadband walkie talkie

Support UV double segment, frequency range: UHF 400.000 – 480.000Mhz; VHF: 136.000 – 174.000Mhz.

  1. DMO True 2-Slot dual time slot

Direct mode dual-slot communication achieves two groups of calls at a frequency point at the same time,

so that the communication efficiency is doubled and frequency resources are saved.

  1. Digital and analog compatible, smooth over

Support DMR digital and analog two communication modes to ensure that the original analog products smooth transition to digital products,

to meet different communication needs.

  1. Digital signaling function

Rich calling modes that support DMR protocol, including single call, group call and all call; S

upports remote inhibit function and other applications.

  1. SMS function

Supports SMS, text editing and draft in 64 characters in chinese and English,

so that text messages calls can be sent when voice call is inconvenient.

  1. High sound quality

This digital two-way radio uses advanced AMBE+2TM voice processing technology to achieve high quality.

  1. Manual writing-frequency

Support channel/ frequency mode, allows manual writing-frequency in frequency mode,

and writing-frequency software can be used to set the required frequency without connecting the computer.
