Retevis RT71 DMR UHF Handheld Transceiver

Main Features
●UHF Full-Frequency Radio
Frequency range: UHF 400.000-480.000MHz
●Digital and analog compatible
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
●Digital signaling function
Rich calling modes that support DMR protocol, including single call, group call and all call; supports remote inhibit function and other applications
●High sound quality
This digital two-way radio uses advanced AMBE +2TM voice processing technology to achieve higher quality
●High/low power switch
5W/1W power switch, Meeting the power requirements of different call distances to save more energy
●Supports the use of repeater
●Side buttons can be customized without changing the user’s operating habits
