This mode should always be set before

prohibited, e.g. in hospitals or in potentially explosive areas.
To activate the TXI Mode:
•Select 
1 Activate, and press Ok.
The terminal will sound the “Transmit Inhibit” tone. The 
display blinks between the Talkgroup name and the message 
TXI Mode, and the solid orange LED indicates the TXI Mode.

The terminal sounds the “Transmit Inhibit” tone and returns 
back to Group Mode or Direct Mode, if Direct Mode was the 
last selected mode.
It is not possible to switch from Direct Mode to Trunk Mode, if 
the terminal is in Transmit Inhibit Mode.
To change the Operation Mode quickly you can use one of the 
programmable keys (if set up by your Service Provider).
All menu options which cause transmitting are blocked in TXI 
Mode. It is not possible to change the Talkgroup.
