■ Opening the fold To use the phone, you must open the fold as shown in the figure. Do not try to force the fold to open more than the hinge allows. Close the fold by pushing from the top part of the phone, not from the hinge. ■ Switching the phone on and off Press and hold the power key for more than 3 seconds. • If the phone asks for a PIN code or security code, key in the code and press OK. • 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. Your device has an internal antenna. Note: As with any other radio transmitting device, do not touch the antenna unnecessarily when the device is switched on. Contact with the antenna affects call quality and may cause the device to operate at a higher power level than otherwise needed. Avoiding contact with the antenna area when operating the device optimises the antenna performance and the battery life. Copyright © 2005 Nokia. All rights reserved. 22
