Motorola MTP850 Ex User Manual page 55

In TXI Mode the MTP850 Ex/MTP810 Ex will not transmit
under any circumstances, except for the Emergency Call,
which can be initiated even if the MTP850 Ex/MTP810 Ex is
in TXI Mode.
All MTP850 Ex/MTP810 Ex functions and keys which cause
transmission, e.g. registration to the network, change of
talkgroup or folder, sending messages, pressing PTT, etc. are
disabled. In this case the display shows "Not Allowed In TXI
Mode" and the MTP850 Ex/MTP810 Ex sounds the "Transmit
Inhibit" tone.
When no danger to safety exists anymore (for instance if you
leave the RF sensitive area), the TXI Mode can be
deactivated and the MTP850 Ex/MTP810 Ex returns to
standard operation.
Setting the TXI Mode is described in "This mode should
always be set before entering areas where transmission is
prohibited, e.g. in hospitals or in potentially explosive areas."
on page 137.
Activated Transmit Inhibit is indicated by the solid orange
LED and flashing between the two displays:
