BF-TD511EX, with its outstanding audio quality, long battery life and rich applications, and has passed ATEX certification, provides reliable communication guarantees for users who work in dangerous work environments full of explosive gas, guaranteeing your secure and efficient connection everywhere.

ATEX Certification
Based on the explosion-proof design of the circuit and structure, and has passed the ATEX certification (Ex ic IIC T4 Gc、Ex ic IIIC T100℃ Dc), BF-TD511EX can play excellent working and safety performance that can be used safely in various extreme work environments which full of explosive, inflammable gas.

VOX
BF-TD511EX supports VOX function so that users can still be in continuous communication without pressing the PTT key frequently in busy application scenarios like riding, outdoor activities, emergency rescue, and facilitating operation and response.

IP65 Protection
BF-TD511EX adopts sealing material in key points against dust and spills to realize IP65 protection; the whole radio is equipped with industrial PC+ABS material that can effectively weaken the shock impact when falling, and ensure normal communication in harsh environments.

One-key Alarm
For emergency response, the one-key alarm function of BF-TD511EX can effectively guarantee personnel safety in dangerous working environments.

TDMA True 2 Timeslots
BF-TD511EX adopts TDMA 2 timeslots technology, which allows users in wider coverage to realize better audio quality, larger capacity, and clearer audio quality. The TDMA True 2 Timeslots trunking technology can dynamically allocate the spare timeslots to the groups that need to talk, easing the communication pressure when multiple groups are communicating at peak times. 2 timeslots communication allows communication to flow smoothly in real time during peak services or emergencies

Digital/Analog Smooth Transition
BF-TD511EX supports both digital and analog modes that can receive digital and analog signals at the same time to compatible analog and digital modes, guaranteeing a smooth transition from analog to digital mode and reducing customer costs.

Voice Encryptions
Thanks to the ARC/AES256 advanced encryption technology, BF-TD511EX provides rock-solid encryption to every communication, preventing sensitive information leakage or eavesdropping during transmission and guaranteeing communication privacy and security.
