Setting up your computer for a Bluetooth 
DUN connection
Dial-up networking must be enabled or 
installed on your computer. Follow the 
instructions from the manufacturer of your 
Bluetooth adapter to enable DUN. Your 
wireless service provider may provide 
customized software programs that walk 
you through the DUN setup process. Check 
with your wireless service provider to see 
if such a program is available.
Accessing the Internet using a Bluetooth 
DUN connection
The steps for accessing the Internet on 
your computer may vary depending on your 
operating system and how Bluetooth 
wireless technology is set up on your 
computer—for example, if it is built in 
versus if you are using a wireless 
Bluetooth adapter. If the following 
procedure does not work with your 
computer, check your computer’s 
documentation for how to set up Bluetooth 
technology to access the Internet using a 
DUN connection.
BEFORE YOU BEGIN You may need to 
use a virtual private network (VPN) to 
access corporate email. Check with your 
system administrator for more information.

paired devices. Check your computer’s 
documentation for how to open this 
screen and for the name of the paired 
devices option.

representing your Treo 750. Your 
computer connects to your Treo 750
