Trade Mark Features

Main Features

•    Broadband walkie talkie

Support UV double segment, frequency range UHF400.000-480.000MHz/VHF136.000-174.000MHz

•    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, 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

•    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

•    SMS function

Supports SMS, text editing and draft in 250 characters in Chinese and English, so that text messages calls can be sent when voice call is inconvenient

•    High sound quality

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

•    Manual writing-frequency

Supports 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

•    High/low power switch

Meets the power requirements of different call distances to save more energy

•    Alarm function

Supports general alarm and silent alarm in emergency situations

•    Digital mode supports the use of relays

•    Side buttons can be customized without changing the user’s operating habits

You can familiarize yourself with the external structure and the functions of programmable buttons of this product in this section.
