TX3820V

Flash upgradeable and programming means that the TX3820U/V can cope with any future operational requirements. The compact modular design provides a flexible approach to installation especially in today’s modern vehicles and a rugged die-cast chassis means that the TX3820U/V will deliver reliable communications in the harshest of environmental conditions. For a traditional DIN sized console, a mounting adaptor kit will allow the TX3820U/V to be installed or removed easily. 
 
Possibly the smallest 25-watt commercial two-way radio, the TX3820U/V also boasts a full range of calling options and a host of practical user functions including an inbuilt speaker, which can be mounted facing up or down to take full advantage of the clear, powerful audio.
