Troubleshooting
Check the power management settings
You may be able to eliminate clicks and pops by changing your system’s power 
management settings.
  “Power management settings” (p. 81)
Try updating the driver of your display adaptor (Windows)
You may be able to eliminate clicks and pops by updating the driver for the display 
adaptor installed in your computer.
Have you set the system’s “Performance” setting? (Windows)
You may be able to solve the problem by changing the “Performance” setting of the 
system.
  “System “Performance” settings (Windows)” (p. 82)
Could other software programs be running?
Close software that you’re not using.
If the window of a Windows program has been closed but it is still shown in the taskbar, 
that program is still running. Close all unneeded software that’s shown in the taskbar.
Have you tried Windows Update or Microsoft Update? (Windows)
Try using Windows Update or Microsoft Update (provided by the Microsoft 
Corporation) to update your system to the latest version.
In the driver settings dialog box, try selecting the “Light Load” check 
box
To change or check this setting, proceed as directed in  “Changing or verifying the 
driver settings (Windows)” (p. 80).
Changes to this setting will take effect after you turn the A-PRO’s power off, then on 
again. Unless you are experiencing problems, you should leave this check box cleared 
(the default state).
Try disabling the LAN
In your computer’s Device Manager, try disabling LAN (wired/wireless).
If this eliminates the clicks and pops, it may be that updating your LAN driver or BIOS 
may solve the problem. Check whether updated software is available.
Could you have connected the A-PRO to a USB hub?
Try connecting the A-PRO directly to a USB connector on your computer.
Are you using the included USB cable?
You must use the included USB cable when using the A-PRO. Some commercially 
available USB cables do not meet the requirements of the USB standard, and this may 
prevent the A-PRO from operating correctly.
Could you have updated the Mac OS X software while A-PRO was 
connected?
It has been found that clicks or pops can occur if you performed a Mac OS X software 
update while the A-PRO was connected. If so, install the driver once again.
