BF-TM8250 is compatible with the SVT system, which provides versatile voice & data services for critical communications. It comes with a large size color display, which delivers good visibility even under strong light. The five programmable buttons allow the user to access any features he needs and thus greatly facilitate ease of use. Besides a full set of digital features, the integrated remote kill/stun/revive features bring unprecedented efficiency to teamwork and radio management.
Transmit Interrupt
This function enables a supervisor to interrupt a radio conversation in order to clear a channel for more important communications.
Radio Priority-Based Interruption
This function enables a radio with higher level to interrupt communication between radios with lower levels, giving higher priority to radios with higher levels. This means better dispatching efficiency.
GPS
BF-TM8250 can send location information to the command center and the commander can view GPS information in realtime, which increases commanding efficiency and personnel safety.
TTS(Text-to-Sound)
The integrated TTS function will automatically transfer all the text messages into voice, so that the user does not need to read and can therefore better focus his eyes and attention on the mission.
RemoteKill/Revive
Such functions greatly facilitate dispatching work and can be especially useful if you want to kill a lost radio.
Secure Communications
Use digital encryption to code and decode all voice calls, and support both dynamic and static encryption for secure communications.
SMS
BF-TM8250 supports messages with up to 140 characters when discreet communications are needed.
DMO True 2-Slot
Indirect mode this radio supports two voice calls simultaneously due to DMR two timeslots, which means two communication paths on 1 frequency at no extra costs or frequency license.
