Cache memory

information requiring passwords, empty the cache after each use. The information or services you have accessed is stored in
the cache. To empty the cache, while browsing, select Options > Other options > Clear the cache. In the standby mode, select

Your device may have some bookmarks loaded for sites not affiliated with Nokia. Nokia does not warrant or endorse these
sites. If you choose to access them, you should take the same precautions, for security or content, as you would with any
Internet site.
Browser security
Security features may be required for some services, such as banking services or online shopping. For such
connections you need security certificates and possibly a security module which may be available on your SIM
card. For more information, contact your service provider.
Security module
The security module can contain certificates as well as private and public keys. The purpose of the security
module is to improve security services for applications requiring a browser connection, and it allows you to use
a digital signature. The certificates are saved in the security module by the service provider.
Select Menu > Web > Settings > Security settings > Security module settings. Select from the following
options:
• Security module details to show the security module title, status, manufacturer, and serial number.
• Module PIN request to set the phone to request the module PIN when using services provided by the
security module. Enter the code and select On. To disable the module PIN request, select Off.
• Change module PIN to change the module PIN, if allowed by the security module. Enter the current module
PIN code, then enter the new code twice.
• Change signing PIN. Select the signing PIN that you want to change. Enter the current PIN code, then enter
the new code twice.
