RadioPRO App (cont.)
Pulsed - This selection will provide a user programmable timed 12v+ output that can be tied to any of the vehicle’s SWC. This
means that when you press the assigned SWC, the red/white wire will pulse for the pre-programmed user time. The range for
pulse time is 100 milliseconds - 25.5 seconds (.1-25.5).
Pioneer Parking Brake - Turning this feature on will make the parking brake output produce the necessary sequencing for
settings menu access. This sequencing is based on the actual parking brake, meaning to produce this sequence you have to
engage the parking brake in the vehicle. If you would like to manually do the necessary parking brake sequencing for Pioneer,
simply leave this feature off. Restoring factory settings on the module will default this setting back to off.
Firmware Updates
The RadioPRO app will also allow you to update the interface with new rmware as it becomes available. Please visit www.pac-
audio.com or contact our tech support department to see if there is a rmware update for your interface.
Product Updates (Firmware)
Chime Volume - Changing this feature will either raise or lower the volume of the warning chimes through the speaker. If
changing from Normal to High then the volume will get louder. If changing from High to Normal then the level will get softer.
Keep in mind that this volume level will effect the rear park assist chimes and the front collision detection.
