If you are concerned about security, turn off Bluetooth or set My phone's visibility to
Hidden. Always accept only Bluetooth communication from others with whom you agree.
Infrared
You can set up the phone to send and receive data through its infrared (IR) port. To
use an IR connection, the device with which you want to establish a connection
must be IrDA compliant. You can send or receive data to or from a compatible
phone or data device (for example, a computer) through the IR port of your phone.
Do not point the IR (infrared) beam at anyone's eyes or allow it to interfere with other IR
devices. Infrared devices are Class 1 laser products.
When sending or receiving data, ensure that the IR ports of the sending and
receiving devices are pointing at each other and that there are no obstructions
between the devices.
To activate the IR port of your phone to receive data using IR, select Menu >
Settings > Connectivity > Infrared.
To deactivate the IR connection, select Menu > Settings > Connectivity >
Infrared. When the phone displays Deactivate infrared?, select Yes.
If data transfer is not started within 2 minutes after the activation of the IR port,
the connection is cancelled and must be started again.
IR connection indicator
When is shown continuously, the IR connection is activated, and your phone
is ready to send or receive data through its IR port. When blinks, your phone
is trying to connect to the other device, or a connection has been lost.
