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.
