Connecting a Device to the USB Port 

Before connecting a USB device to the MobilePro 900, install a ferrite core on 
the USB cable. Installation of the ferrite core on the USB cable reduces radio 
interference when you use a USB device connected to the MobilePro 900. Ferrite 
cores ship with the MobilePro 900. 

Note   

The USB PC Connect cable that ships with the MobilePro 900 

comes with a ferrite core installed. You do not need to install a ferrite core on 
this cable. 

Install a ferrite core on any other USB cable you connect to the MobilePro, 
including the cable attached to a USB mouse or USB keyboard. 

To reduce radio interference when using a USB 

device, be sure the USB cable has a ferrite core installed. 

Use the following procedure to install the ferrite core.  

1. 

Locate one of the ferrite cores that ships with the MobilePro 900.
