Accessory Connector
8.3.10 Emergency
If an emergency switch is assigned, asserting the input causes the radio to go into emergency
mode.
Emergency switch assigned to pin 9 is a special case. In addition to normal emergency mode,
asserting the input when the radio is turned off will invoke Emergency with Wake Up. This causes
the radio to power up and immediately enter Emergency mode.
8.3.11 Ignition
Ignition sense is programmable per radio. Connecting the vehicle ignition to this line causes the
radio to turn on automatically when the ignition is turned on (provided that the on/off/volume knob is
also in the ON position), and turn the radio off when the ignition is turned off. This feature is
particularly useful where the radio must always be on when the vehicle is in use, for example, a fire
engine.
Benefits
The radio turns on automatically when the vehicle is started.
