Your radio can still receive and displays any incoming SDS messages. These messages are stored in
the Inbox.
When no danger to safety exists anymore, for example, when you leave the RF sensitive area, you can
deactivate the TXI Mode and the radio returns to standard operation.
You can deactivate the mode by selecting Menu → Networks → TXI Mode → Deactivate, or pressing
One-Touch Button.
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 TXI mode, when the radio is camped on a cell, it sends a specially
designated Short Data Service (SDS) status message. This SDS message indicates to the SwMI that
the radio is entering or exiting TXI mode.
Mobility procedures that do not require the radio to send an uplink transmission are performed except
for cell reselection.
If the radio is turned off in the TXI mode, on turning on, the radio asks whether to exit the TXI mode. If
you choose No, the radio turns off.
