Transmit Inhibit Mode
The Transmit Inhibit Mode is a mode in which the radio sends no radio transmissions. It is
recommended to activate the mode in RF sensitive areas, for example hospitals, airplanes, where
safety can be jeopardized due to transmission radiation.
To activate, select MENUNetworksTXI ModeActivate.
In this mode, the radio does not transmit under any circumstances except for the Emergency Calls. All
the functions and keys which cause transmission, for example registration to the network, changing
talkgroup or folder, sending SDS messages, or pressing the PTT button are disabled. Any transmission
trial causes the radio to display Not Allowed In TXI Mode notification and to play a tone.
Your radio can still receive:
Group calls.
Messages — stored in the Inbox.
Private call attempts — stored in the Missed Calls list, without the option to respond.
When no danger to safety exists anymore (for example, you leave the RF sensitive area), you can
deactivate the Transmit Inhibit Mode and the radio returns to standard operation.
You can deactivate the mode by selecting MENUNetworksTXI ModeDeactivate, pressing
One-Touch button, or implicitly when initiating an Emergency Call.
NOTICE: RF Transmissions from the radio are prevented under the following conditions:
TXI Mode is activated.
The radio is turned off.
On entering or exiting the transmit inhibit mode, when the radio is camped on a cell, it sends a
specially designated SDS status message. This SDS message indicates to the SwMI that the radio is
entering or exiting transmit inhibit mode.
Mobility procedures that do not require the radio to send an uplink transmission are performed except
for cell reselection.
