DMO True 2-Slot

In direct 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.

GPS Positioning and Tracking

You can track vehicles and assets without having to purchase, install or maintain additional equipment. It can send its GPS position to the dispatch system in real-time.

Multi Sites Roaming Function

Create wide coverage by automatically roaming from one coverage area to another without any manual operations.

Status Voice Prompt

This user-friendly function enables the driver to keep the eyes on the road.

IP54 Dust& water Protection

BF-TM8250 is built to withstand tough environments.

Radio Priority-based Interruption

This function enables a radio with higher level to interrupt communications between radios with lower levels, giving higher priority to radios with higher levels. This means better dispatching
efficiency.

Transmit Interrupt

This function enables a supervisor to interrupt a radio conversation in order to clear a channel for more important communications. This greatly facilitates dispatching work.
