1. AP F8.9 bit operating problems
If, when calibrating the system with AP F8.9 bit connected to a laptop there are operating problems, try
disconnecting the laptop power supply cable.
With the laptop working on battery power you avoid a possible voltage difference in the USB ground between
the vehicle (AP F8.9 bit) and the ground (PC).
2. Connection lost between AP F8.9 bit and the PC
If, while calibrating the system with the PC connected to AP F8.9 bit, the amplifier is turned off and back on again,
the connection is lost and the software cannot finalize the adjustments that were set. To avoid losing the
settings, proceed as follows:
a. Save the setup to a file on the PC using the FILE / SAVE SETUP function.
b. Exit the software.
c. Turn AP F8.9 bit on.
d. Launch the software again.
e. Load the setup file again that was saved using the FILE / LOAD SETUP function.
3. AP F8.9 bit does not respond
If calibrating the system with the PC connected to AP F8.9 bit and the latter does not respond to the commands,
proceed as follows:
a. Turn off AP F8.9 bit by pressing the knob on the DRC or disconnecting the Remote IN or even disconnecting
the power cable for a second.
b. Save the setup to a file on the PC using the FILE / SAVE SETUP function.
