The display and the keypad are illuminated by a 
backlight. When you press any key the backlight 
illuminates. It turns off if no key is pressed within a 
given period of time, depending on the Backlight 
menu option. See page 102 for further details.

Note: The backlight remains on at all times when the 

phone is connected to an optional car kit.

The service light’s activity depends on the Service 
light menu option. See page page 109. The colour 
of service light is also selectable from the option.

The service light will also flash, when you set the 
SMS message, MMS message and incoming call 
alert to Light only.

When you subscribe to a cellular network, you are 
provided with a SIM card loaded with your 
subscription details, such as your PIN, any optional 
services available and so on.

• Keep all miniature SIM cards out of the reach of 

small children.

• The SIM card and its data can be easily damaged 

by scratches or bending, so be careful when 
handling, inserting or removing the card.

• When installing the SIM card, always make sure 

that the phone is switched off before you remove 
the battery.

1. If necessary, remove the battery by referring to 

page 19.

2. Insert and slide the SIM card under the two 

tabs, ensuring that the notched corner is top left 
and the gold contacts of the card face into the 
phone.
