Ignition Switch Options
The Ignition Switch Options feature is configured in the Customer Programming Software (CPS) and it
determines the functionality of the radio based on the ignition state of the vehicle.
The available options are:
Blank
This option allows you to turn on/off the radio through the Power button regardless of the current
state of the ignition.
Transmit Inhibit
This option allows you to turn on/off the radio through the Power button regardless of the current
state of the ignition. If the ignition is not present, all transmissions are inhibited. This includes
receiving any trunking dispatch communications as the radio is not affiliated with the trunking
systems.
PTT Transmit Inhibit
This option allows you to turn on/off the radio through the Power button regardless of the current
state of the ignition. If the ignition is not present, all PTT button transmissions are inhibited.
However, the radio is able to affiliate with the trunking systems.
Required
This option allows you to turn on the radio only if ignition is present. The radio turns off either
through a Power button press or when the ignition is lost. If the radio turns off due to ignition being
removed, it automatically turns on when the ignition is present.
If the radio is configured with the Auto Power Off Timer, it automatically turns off after being inactive
for a period (with or without ignition).
Soft Power Off
This option allows you to turn on the radio either through the Power button or when the ignition is
detected. Meanwhile, if the Power button is pressed or the ignition is removed, the radio turns off.
If the radio is configured with the Auto Power Off Timer, it automatically turns off after being inactive
for a period (with or without ignition).
Ignition Only Power Up
In this option, the radio turns on only when ignition is detected and turns off when ignition is
removed. It does not turn on/off with the Power button press.
