INSTALLATION INSTRUCTIONS

AX-DSP

• Chime Volume -

The best way to identify if the vehicle

requires the AX-DSP to generate the

chimes is to leave the OE ampliﬁer

connected and disconnect the OE

radio, with ignition off and the

driver’s door open, turn-on the

headlights. If chimes are heard

coming through the factory speakers,

there is a digital ampliﬁer and the

chime feature will be required to

maintain that feature in the vehicle.

Note:

If the OE ampliﬁer produces the vehicle’s chimes, use this feature to add them back into the system.

Note:

The slider bar will control the volume of the chime. 10 sets the chimes to their maximum level and 1

sets them to the minimum level.

Note:

In newer Ford vehicles, when disconnecting the OE ampliﬁer, chimes and sensor sounds will re-direct

to sound through the gauge cluster.

Last and the most important:

You Must Lock Down Your Conﬁguration!!!
