In TXI Mode the MTM800 Enhanced will not transmit under
any circumstances, except for the Emergency Call, which
can be initiated even if the MTM800 Enhanced is in TXI
Mode.
All MTM800 Enhanced 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 MTM800 Enhanced 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 MTM800 Enhanced returns to standard
operation.
Setting the TXI Mode is described in “Setting Transmit Inhibit
(TXI) Mode” on page 139.
Activated Transmit Inhibit is indicated by the solid orange
LED and flashing between the two displays:
Dynamic Group Number Assignment (DGNA)
DGNA provides the ability for a network operator or
authorised user to dynamically allocate new, or update
existing talkgroups to selected terminals over the air
interface.
Radiation of the MTM800 Enhanced is only suppressed if the
TXI Mode is activated or the MTM800 Enhanced is separated
from power supply.
