High Performing Communication
Comprehensive User Safety
High Performance Communication
The MTP850Ex delivers best in class audio performance in the typical noisy environments where specialist users from industry or public safety operate.
Comprehensive User Safety
The MTP850Ex can be used in explosive gas and dust environments due to its high level of protection – including dust Zone 21 and 22. Operational safety is further enhanced with a range of features including:
Simple but Powerful User Interface
The simplified keypad with large button surface makes the MTP850Ex easy to use with gloves. Combined with the large scalable display fonts and icons, the MTP850Ex facilitates operation in difficult environments with limited visibility.
Data Applications Capability
The integrated WAP browser and Multi-Slot packet data enables rapid access to critical information in the field. Applications are further enhanced with ability to have simultaneous Short Data Service (SDS) and Multi-Slot packet data services via TNP1 protocol.Internal “Man Down” alarm.
