Cache memory
A cache is a memory location that is 
used to store data temporarily. If you 
have tried to access or have accessed 
confidential 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 Menu > Web > Clear 
the cache.
Browser security
Security features may be required 
for some services, such as online 
banking or 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 improves 
security services for applications 
requiring a browser connection, and 
allows you to use a digital signature. 
The security module may contain 
certificates as well as private and 
public keys. The certificates are 
saved in the security module by the 
service provider. 
Select Menu > Web > Settings > 
Security settings > Security 
module settings and 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 ask for 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 — to change 
the signing PIN code for the digital 
signature. Select the signing PIN you 
want to change. Enter the current 
PIN code, then enter the new code 
twice.

Certificates
Important: Note that even if 
the use of certificates makes 
the risks involved in remote 
connections and software 
installation considerably 
smaller, they must be used 
correctly in order to benefit 
from increased security. The
