My battery didn’t last as 
long as I expected. What 
can I do to extend battery 
life? 
Your battery’s performance is affected by charge 
time, feature use, temperature changes, and 
other factors. For tips on extending your battery 
life, see “Battery Use”. 
I plugged the data cable 
into my phone but my 
phone did not beep. How 
do I know if the data cable 
is ready to go? 
The beep indicates that you are set up correctly. If 
you did not hear a beep, make sure that both 
ends of the data cable are connected - the 
smaller end to your phone and the larger end to 
your computer. 
Finally, your computer may have deactivated the 
port to save power. Try opening an application 
that uses the port, like a fax or dial-up 
application, and your computer will automatically 
activate the port. 
My phone beeped when I 
attached the data cable, 
but my fax and data 
applications don’t work. 
Some wireless networks may not support data or 
fax transmission. If you are roaming on an 
unfamiliar network, this may be the case. 
Also, remember that data and fax transmission 
usually requires a subscription. Call your service 
provider for more information.
