Getting started ■ Switching the phone on and off Warning: Do not switch the phone on when wireless phone use is prohibited or when it may cause interference or danger. Press and hold the power key . Note that if the phone displays Insert SIM card even though the SIM card is properly inserted, or SIM card not supported, contact your network operator or service provider. Your phone does not support 5 Volt SIM cards and the card may need to be changed. • If the phone asks for a PIN code, key in the PIN code (displayed as ****), and press OK. See also PIN code request in Security settings on page 80 and Access codes on page 14. • If the phone asks for a security code, key in the security code (displayed as *****), and press OK. See also Access codes on page 14. ■ Normal operating position Use the phone only in its normal operating position. Your phone has a built-in antenna. As with any other radio transmitting device, do not touch the antenna unnecessarily when the phone is switched on. Contact with the antenna affects call quality and may cause the phone to operate at a higher power level than otherwise needed. Not touching the antenna area during a phone call optimises the antenna performance and the talktime of your phone. Copyright © 2004 Nokia. All rights reserved. 27
