Settings These codes can only include the numbers from 0 to 9. If you forget the PIN or the PIN2 code, contact your service provider. If you forget the lock code, contact a Nokia Care point or your service provider. See "Access codes", p. 17. Avoid using access codes similar to the emergency numbers to prevent accidental dialling of the emergency number. ● Keypad autolock period - Select whether the keypad is locked when your device has been idle for a certain period of time. ● Phone autolock period - To avoid unauthorised use, you can set a time-out after which the device automatically locks. A locked device cannot be used until the correct lock code is entered. To turn off the autolock period, select None. Tip: To lock the device manually, press the power key. A list of commands opens. Select Lock phone. In the offline or flight profiles, you may need to unlock the device and change to the calling profile before making a call. ● Lock if SIM card changed - You can set the device to ask for the lock code when an unknown SIM card is inserted into your device. The device maintains a list of SIM cards that are recognised as the owner's 152 cards. ● Closed user group - You can specify a group of people to whom you can call and who can call you (network service). When calls are limited to closed user groups, calls may be possible to the official emergency number programmed into your device. ● Confirm SIM services - You can set the device to display confirmation messages when you are using a SIM card service (network service). Certificate management Press , and select Tools > Settings > General > Security > Certificate management. Digital certificates do not guarantee safety; they are used to verify the origin of software. In the certificate management main view, you can see a list of authority certificates that are stored in your device. Scroll right to see a list of personal certificates, if available. Digital certificates should be used if you want to connect to an online bank or another site or remote server for actions that involve transferring confidential information. They should also be used if you want to reduce the risk of viruses or other malicious software and be sure of the authenticity of software when downloading and installing software.
