Main Features
●UHF Full-Frequency Radio Frequency range:UHF400.000-470.000MHz ●DMO True2-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 ●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 2W/0.5W power switch, Meeting the power requirements of different call distances to save more energy ●Alarm function Supporting general alarm and silent alarm in emergency situations ●Digital mode supports the use of repeater ●Side buttons can be customized without changing the user’s operating habits

Good quality battery with high/low power switch
Large capacity battery with USB rechargeable can support more then 12 hours use life are enough for your standard work shifts; Even if when working overtime or working long hours outdoors, you will not need to worry about the battery issue
Emargency alarm function
When you use the function,walkie talkies will send out a distress call. Other radios within range will alert with the distress call;Retevis RT53 UHF Walkie talkies supporting general alarm and silent alarm
DMO true2-slot dual time slot
Direct mode dual-slot communication achieves two groups of calling at a frequency point at the same time, so that the communication efficiency is doubled and frequency resources are saved
Hands free function
The hands free function allows you to operate by voice activation when you are busy without pressing the PPT and and you can select the vox levels to the background noise
High power of wider transmission rang
Different from FRS two way radios, Retevis RT53 digital/analog 2 way radios with higher power ensure that you can get broad transmission range and powerful penetration,UHF full-frequency radio can penetrate buildings and has good performance in the outdoors
Digital mode supports the use of repeater
A repeater capable radio has the ability to have the transmit (TX) and receive (RX) frequencies for a single channel set to different values. Retevis RT53 DMR radios communicate through a repeater - a device that amplifies a radio signal, greatly increasing range
