Setting Up the Data Function
You can connect the MTP850 to an external device (such as
a laptop or desktop PC). The MTP850 will then be capable of
transmitting and receiving data from the external device. To
connect the MTP850 accessory connector to the external
device, use cable FKN4897. The external device must run an
application complying with the TETRA standards.
From the main menu, select Setup > Data
Setup.
The display shows the current setting:
• Voice Only — The MTP850 will receive
and transmit voice calls only.
• Data Only — The MTP850 acts as a
modem. The MTP850 will reject incoming and outgoing
voice calls (except for Emergency Calls), status and text
messages.
• Voice & Data — The MTP850 acts as a modem but voice
calls will have priority over data calls and will interrupt
them.
Scroll to the desired setting and press Select.
In Data Only and in Voice & Data, the Data Connected icon is
displayed after you have connected the MTP850 to the
external device and the MTP850 is ready for data transfer.
The Data Transmit/Receive icon is displayed to indicate data
is being transferred to/received from the external device.
The MTP850 ends the Ambience Listening (AL) call and the
microphone is closed when the MTP850 is in one of the
following states:
• Entering the out-of-service area
• Outgoing packet data call setup
To exit data, return to Data Setup and select Voice Only.
The MTP850 returns automatically to Voice communication.
Data services are available only in TMO. Data Services are
blocked in TXI Mode.
