My device doesn’t make any sound. 
Check the Sounds settings by tapping Start 
> Settings > Personal tab >Sound & 
Notifications. Check the Volume Control, 
the speaker may be muted. 
My device’s sound only can be heard from 
the headset. 
Make sure the jack is clean and free from 
foreign particles. Re-inserting the headset 
plug into the Audio Jack and then 
unplugging it may help sometimes. Check 
to ensure the headset is supplied with the 
device. 
 Connection & Bluetooth 
I can not connect to the internet; Web 
surfing doesn’t work. 
Make sure you have set up and connected 
to T-Mobile GPRS. The wireless 
connection to the network must be 
switched on, and the signal must be 
unobstructed.  
I can’t perform over-the-air 
synchronization. 
Synchronization to a server allows your 
device to sync, over-the-air (OTA), directly 
to a Microsoft Exchange 2003 Server. This 
allows you to update your e-mail, contacts, 
calendar, and tasks information securely 
from any location with data connectivity. 
In order to use this functionality, you do 
not need a PC running; however, it does 
require your IT administrator to enable you 
to use this service. 
Unable to use Infrared (IR) to transfer 
information. 
Transfer only one file, or no more than 25 
contact cards, at a time. Line up the IR 
ports so that they are unobstructed and 
within close range. Make sure nothing is 
between the two IR ports. Adjust the room 
lighting. Some types of light interfere with 
IR connections. Try moving to a different 
location or turning off some lights. Do not 
try to use infrared beaming in the sunlight. 
I cannot end a Bluetooth connection. Turn 
Bluetooth connection off with 
Communication Manager. 
I cannot find another Bluetooth enabled 
device. 
Make sure the Bluetooth function on the 
other device is activated. Also, ensure you 
are within 10 meters of each other, and 
there are no obstructions. Finally, make 
sure the other device is set in 
“Discoverable” mode.
