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 M
ENU
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 M
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.
• Battery is removed.
• 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.
In transmit inhibit mode the radio joins group calls for any group that the radio is monitoring, but the
transmitting on that call is still prohibited.
The radio also displays any incoming SDS messages to the user. The missed call feature is active in
the transmit inhibit mode and allows checking what calls were missed. However, the radio attempts to
prevent call setup retransmission from being recorded as separate calls.
If you initiate an emergency call, the radio immediately leaves transmit inhibit mode and attempts to
start the emergency call if the radio is in service.
If the radio is turned off in the transmit inhibit mode, on turning on the radio asks whether to exit the
transmit inhibit mode. If you choose No, the radio turns off.
