Transmit Inhibit

The Transmit Inhibit feature allows you to stop all transmission including voice and data. The radio can

receive messages but is not able to reply the acknowledgment request of the received message.

This feature is available for APCO 25 Trunking, Type II Trunking, and Conventional operations for all

APX radios.

You can physically control the transmission of the radio especially during operation in hazardous

environments. An environment is considered hazardous if radio transmission could initiate an explosion

or other dangerous reactions.
