ADVANCED FEATURES
This feature allows the user to select the radio’s functionality
based on the Ignition State of the radio user’s vehicle. The
available options are as follows.
Blank
This option allows the user to power on and power off the
radio through the Power button regardless of the Ignition’s
current state.
Tx Inhibit
This option allows the user to power on and power off the
radio through the Power button regardless of the Ignition’s
current state. In addition, if the Ignition is not present, then all
transmissions are inhibited. This includes receiving any
Trunking dispatch communications since the radio will not
affiliate with the Trunking systems.

due to the ignition being removed.

Power Off Timer expires, or, when Ignition Auto Power Off
Timer expires.
