Dual Positioning System
BF-TD935 supports pure Beidou, GPS + Beidou dual positioning systems, and supports voice call embedded positioning information, displaying the real-time relative position of the two sides of the communication information. When accessing the communication system, it can quickly and accurately lock the position information of the personnel, to deal with all kinds of emergencies more easily.
 
IP68 Protection
BF-TD935 meets IP68 and MIL-STD-810 MIL protection standards, can withstand 2 meters of fall and shock at multiple angles, and can still be used normally after being immersed in 2 meters of water for 2 hours, which ensures that the equipment can be used stably for long time in rain, snow, high temperature and humid environments, and gives the user a more reliable protection at the critical moment.
 
*Bluetooth Connection
BF-TD935 can be easily connected to a Bluetooth headset and wireless PTT, etc., the user does not need to hold the radio to realize the free operation of both hands, which is convenient user operation without wired constraints.
 
*Voice Recording
BF-TD935 is equipped with 24 hours and 6 hours recording function, and can record communication on the radio during the calls, providing a guarantee for the review of critical tasks and information forensics.

Rich Communication Version Options
BF-TD935 provides rich, flexible communication version options, supporting adjust various communication systems: DMR/PDT standard mode, DMR/PDT Trunking system, same frequency relay, Ad-hoc system, SVT Trunking system, SDC system, meet the different scenarios from daily communication to group collaborations, and create an ideal communication solution for users in different industries, providing the best solutions for users in different industries.
