DMR Tier II mobile radio TM8250 is designed to use in the smart dispatch patrol system which provides versatile voice and data service for critical communication. with a multi-sites roaming function, TM8250 creates wide area coverage and automatically roams from one coverage area to another with no manual intervention. Featured with superb audio, integrated GPS, text messaging TM8250 enables you to keep track of every organization member and keep in touch at all times. Voice announcement for different statuses frees users to concentrate on the work.

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.
 
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.
 
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 eyes on the road.
 
Radio Priority-based Interruption
this function enables a radio with a higher level to interrupt communications between radios with lower levels. this means better dispatching efficiency.
 
Bright, Color LCD Display
the built-in high contrast color display is easy to read in all kinds of light.
 
Power-on Password
Nobody can mess with your work.
 
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.
