device.

3. Wait a few seconds until an infrared connection is established.
4. To send, locate the desired file in an application or the file manager, and select

Via infrared

If data transfer is not started within 1 minute after the activation of the infrared port, the connection is cancelled and must be

started again.
All items received through infrared are placed in the Inbox folder in

Messag.

Positioning devices away from each other breaks a connection, but the infrared light beam remains active on your device until

it is deactivated.

Data connections

Packet data

GPRS (general packet radio service) enables wireless access for mobile phones to data networks (network service). GPRS uses

packet data technology where information is sent in short bursts of data over the mobile network. The benefit of sending data

in packets is that the network is occupied only when sending or receiving data. As GPRS uses the network efficiently, it allows

for quick data connection set-up and fast data transmission speeds.
You must subscribe to the GPRS service. For availability and subscription to GPRS, contact your network operator or service

provider.
Enhanced GPRS (EGPRS) is similar to GPRS, but it enables faster connection. For more information on the availability of EGPRS

and data transfer speed, contact your network operator or service provider. Note that when you have selected GPRS as a data

bearer, the device uses EGPRS instead of GPRS if this is available in the network.
During a voice call, you cannot establish a GPRS connection, and any existing GPRS connection is put on hold unless the network

supports dual transfer mode.

UMTS

UMTS (Universal Mobile Telecommunications System) is a 3G mobile communication system. Besides voice and data, UMTS

enables audio and video delivery to wireless devices.
Your device can automatically switch between the GSM and UMTS networks.
To select which network to use, select

The GSM network is indicated with , the UMTS network with .
When you use your device in GSM and UMTS networks, multiple data connections can be active at the same time, and access

points can share a data connection. In the UMTS network, data connections remain active during voice calls. You can, for example,

browse the Web faster than previously possible while simultaneously speaking on the phone.

Wireless local area network (WLAN)

Some places, like France, have restrictions on the use of wireless LAN. Check with your local authorities for more information.
Features using wireless LAN, or allowing such features to run in the background while using other features, increase the demand

on battery power and reduce the battery life.
This device can detect and connect to a wireless local area network.
If you move the device to another location within the wireless LAN and out of range of a wireless LAN access point, the roaming

functionality can automatically connect your device to another access point that belongs to the same network. As long as you

remain within range of access points that belong to the same network, your device can stay connected to the network.

Tip: A wireless LAN connection is established when you create a data connection using a wireless LAN Internet access

point. The active wireless LAN connection is ended when you end the data connection.

Your device enables different types of communication in a wireless LAN. The two operating modes are infrastructure and ad

hoc.
• The infrastructure operating mode allows two kinds of communication: wireless devices communicate with each other

through a wireless LAN access point or wireless devices communicate with a wired LAN device through a wireless LAN access

point. The advantage of the infrastructure operating mode is that you can have more control over network connections

because they pass through an access point. A wireless device can access the services that are available in a regular wired LAN:

company database, e-mail, the Internet, and other network resources, for example.

• In the ad hoc operating mode you can send data to and receive it from other devices with compatible wireless LAN support ,

for example, to be printed. These functions may require an additional third party application to work. No wireless LAN access
