Sometimes you may be working in areas that are sensitive to Radio Frequency (RF) signals such as
healthcare facilities. To continue operating your radio in these areas, you can set your radio to

operational state of your radio. You cannot activate Transmit Inhibit when you are in a call.

You cannot select Transmit Inhibit if user profile Do Not Disturb is selected. See User profiles on
page94.
Your radio automatically leaves Transmit Inhibit mode when you power it off; when powered on
again Transmit Inhibit is not activated.
