Retevis RB22 DMR radio is a 5W portable digital and analog two way radio featuring TDMA technology, a 1.77-inch color screen with a half-keyboard, and a removable antenna. It utilizes TDMA technology to attain double call capacity on a permitted frequency. Low noise, crystal clear sound, as well as encryption communication.
Support Digital & Analog modes
The RB22 DMR radio has both digital and analog modes. When it is changed to mixed reception mode (promiscuous mode), it will support both analog and digital modes at the same time. In digital mode, it will allow more operations, such as remote kill/stun/activate, single/group/all call, emergency alert, and so on.
Up to 4000 Channels and 16 Zones
It has 16 zones, each zone has up to 250 channels, so in fact, it has 4000 channels in total. Users can program all the channels and zones according to their own needs.
Support TDMA Mode
The TDMA stands for Time Division Multiple Access. RB22 DMR radio utilizes TDMA to allow several users to share the same frequency channel by dividing that signal into different time slots. Each frequency has a slot 1 or slot 2, and each slot can be used by different users. It can realize two sets of simultaneous communication at the same frequency point, which greatly improves communication efficiency and avoids busy channel and call interference.
1.77-inch Color Display and Half-Keypad
The RB22 DMR radio has a 1.7-inch color screen for easy viewing and a power function menu for quick adjusting settings via the keypad.
Long Standby Time

Hands-Free Operation
The integrated VOX (Voice Operated Exchange) feature enables voice-activated transmission, freeing your hands for other tasks. The included earpieces help improve the sound quality and also ensure the call information privacy.
