Transmit Inhibit Mode; Emergency Operations - Motorola ST7000 Feature User Manual

3.4

Transmit Inhibit Mode

The Transmit Inhibit (TXI) Mode is a mode in which the radio sends no radio transmissions. Activate
this mode in RF sensitive areas, for example hospitals, airplanes, where safety can be jeopardized due
to transmission radiation.
To activate, select Menu/OK → Networks → TXI Mode → Activate.
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, 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.
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/OK → Networks → TXI Mode → Deactivate, 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 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.
In TXI mode, the radio joins group calls for any group that the radio is monitoring, but the transmitting
on that call is still prohibited.
If you initiate an emergency call, the radio immediately leaves TXI 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 press the Back touch icon, the radio turns off.

Emergency Operations

Emergency Operations are used in critical situations.
Your service provider can configure the P1 Programmable button as an Emergency button.
Pressing and holding the Emergency button activates one or more services (depending on your
service provider settings).
When starting Emergency Operations, any ongoing voice call is aborted or cleared down.
During Emergency Operations, the radio rejects phone, PABX, and private calls, and does not monitor
the talkgroups in the selected scan list.
To terminate Emergency Operations, press and hold the Back key.
